'''''The Christmas Invasion''''' was the 2005 [[Christmas Special]] of ''[[Doctor Who]]''.
 
It was the show's first Christmas special since its revival and the first Christmas special starring [[David Tennant]] as [[Tenth Doctor|the Doctor]].
 
It was the first episode of ''[[Doctor Who (TV series)|Doctor Who]]'' to premiere on [[Christmas Day]] since "[[The Feast of Steven]]", the seventh part of 1966 twelve-part serial ''[[The Daleks' Master Plan (TV story)|The Daleks' Master Plan]]''. However, unlike that episode, ''The Christmas Invasion'' was specially commissioned by [[BBC One]] to be transmitted outside the programme's normal broadcasting season. It was thus the first in the modern tradition of the "[[Christmas special]]", and its sixty-minute running time made it then the longest episode yet produced by [[BBC Wales]].


'''The Christmas Invasion''' was an episode of ''[[Doctor Who]]'', broadcast on [[Christmas Day]] [[2005]]. It was also [[David Tennant]]'s first full episode (not counting the [[Children in Need Special]]) as the [[Tenth Doctor]].
Narratively, it continued the story of [[Harriet Jones]], started the [[Torchwood Institute|Torchwood]] [[story arc]] and involved [[UNIT]] in its first major appearance in the new series.


==Synopsis==
More importantly, it was the first full story to feature the [[Tenth Doctor]], played by [[David Tennant]]. Its initial pre-titles sequence on the [[Powell Estate]] was later used to "bookend" the closing scenes of ''[[The End of Time (TV story)|The End of Time]]''. Its setting was the first and last place on [[Earth]] the Tenth Doctor saw.
While [[Rose Tyler|Rose]], [[Jackie Tyler|Jackie]], and [[Mickey Smith|Mickey]] try to help the Doctor as he suffers the instabilities of [[regeneration|post-regenerative]] shock, the [[Earth]] comes under attack by a sinister race known as the [[Sycorax]].


==Plot==
To coincide with this release, three short stories were released on the [[U.N.I.T. (tie-in website)|U.N.I.T. website]]. The first was ''[[Alien Life (short story)|Alien Life]]'', part of the ''[[UNIT Press Briefings (series)|UNIT Press Briefings]]'' mini-series, which was set directly in the aftermath of the [[Sycorax invasion of Earth|Sycorax invasion]], where UNIT confirms that aliens exist, and the second and third, ''[[Guinevere One (short story)|Guinevere One]]'' and ''[[Project Rooftop (short story)|Project Rooftop]]'', part of the ''[[Operations Board (series)|Operations Board]]'' mini-series, was set during and after ''The Christmas Invasion'', respectively, depicting events of the television story from UNIT's perspective.
It is [[Christmas]] Eve on [[Earth]], as [[Jackie Tyler|Jackie]] prepares presents and [[Mickey Smith|Mickey]] works in the garage, both of them hear the distinctive sound of the [[the Doctor's TARDIS|TARDIS]]' engines. Rushing out into the street of the [[Powell Estate]], they see the TARDIS blink into existence above them, ricochet off a few buildings and a post van, then come to a crashing halt. A strange man stumbles out of the [[police box]] doors, greets them by name and wishes them a merry Christmas before collapsing. [[Rose Tyler|Rose]] follows and, to Jackie and Mickey's questions, identifies the stranger as [[Tenth Doctor|the Doctor]].


They bring the Doctor to Jackie's flat and dress him in pajamas belonging to [[Howard]], Jackie's current beau, who has the habit of keeping pieces of fruit in his pocket for snacks. While Rose discusses the Doctor's change of appearance with Jackie, they do not see a wisp of vortex energy emerging from the Doctor's mouth, which then floats into space. On television, [[Prime Minister]] [[Harriet Jones]] and project director Daniel Llewellyn give a press conference about the [[Guinevere One]] space probe, which is about to land on [[Mars]]. In space, however, the probe is swallowed up by an island-like spaceship.
== Synopsis ==
It's [[Christmas Eve]] and high above [[London]], the alien [[Sycorax]] are holding the [[Earth]] for ransom. The [[Tenth Doctor]] must recover from his [[regeneration]] in time to save the [[human]] race from [[slavery]].


That evening, Rose and Mickey go Christmas shopping, but are attacked by a group of masked [[Santa Claus|Santas]] armed with lethal musical instruments. Managing to escape when the tuba mortar brings a giant [[Christmas tree]] down on the Santas, Rose realises that the Santas must be after the Doctor. She and Mickey rush home. When they reach the flat, Rose notices an unfamiliar Christmas tree in the sitting room, which Jackie says was delivered to the door. As they realise that none of them purchased the tree, it comes to life, whirling around with razor-sharp branches.
== Plot ==
It is [[Christmas]] [[Christmas Eve|Eve]] on [[Earth]]. As [[Jackie Tyler|Jackie]] prepares presents and [[Mickey Smith|Mickey]] works in the [[Clancy's|local garage]], both of them hear the distinctive sound of [[the Doctor's TARDIS|the TARDIS]]'s engines. Rushing out into [[Maddock Way|the street]] of the [[Powell Estate]], they see the TARDIS blink into existence above them, ricochet off a few buildings and a post van, then come to a crashing halt. A freshly-regenerated Doctor stumbles out of the [[police box]] doors, greets the two of them by name and wishes them a merry Christmas before collapsing. [[Rose Tyler|Rose]] follows and, in response to Jackie and Mickey's questions, identifies him as the Doctor.


The three retreat to the bedroom, the "Christmas tree" in hot pursuit. Rose places the [[sonic screwdriver]] in the still-comatose Doctor's hand and asks him to help her. Reacting instinctively, the Doctor rises as the tree bursts through the door and disintegrates the tree with the screwdriver. He then strides outside the flat to see who was remotely controlling the tree. From ground level, the Santas stare up at the Doctor, but [[teleportation|transmat]] away when the Doctor points the sonic screwdriver at them. The Doctor calls them "[[pilot fish]]" and collapses in pain, saying that Rose woke him up too soon: he is still regenerating. The energy leaking from him has attracted attention, and if the "pilot fish" could trace it, then something bigger is coming. He then loses consciousness again.
They bring the Doctor to Jackie's flat and dress him in pyjamas belonging to [[Howard (The Christmas Invasion)|Howard]], Jackie's current beau, who has the habit of keeping pieces of fruit in his pocket for snacks. While Rose discusses the Doctor's change of appearance and the fact he has [[Binary vascular system|two hearts]] with Jackie, they do not see a wisp of regeneration energy emerging from the Doctor's mouth, which then floats off into space. On [[television]], [[Prime Minister]] [[Harriet Jones]] and project director [[Daniel Llewellyn]] give a press conference about the ''[[Guinevere One]]'' space probe, which is about to land on [[Mars]]. In space, however, the probe is swallowed up by an rock-like spaceship.

That evening, Rose and Mickey go [[Christmas shopping]] but are attacked by a group of [[Roboform|masked Santas]] armed with lethal musical instruments. Managing to escape when the tuba mortar brings a giant Christmas tree down on the Santas, Rose realises that their attackers are after the Doctor. She and Mickey rush home in a [[Taxi driver (The Christmas Invasion)|taxi]]. When they reach the flat, Rose notices an [[Roboform Christmas tree|unfamiliar Christmas tree]] in the sitting room, which Jackie says was delivered to the door. As they deduce that none of them purchased the tree, it suddenly comes to life, whirling around with razor-sharp branches while playing a cheerful rendition of "Jingle Bells" as it tries to slice them all to ribbons. The three retreat to the bedroom with the tree in hot pursuit. As Jackie laments the indignity of being "killed by a Christmas tree", Rose places the [[the Doctor's sonic screwdriver|sonic screwdriver]] in the still-comatose Doctor's hand and begs him to help her. Reacting instinctively, the Doctor rises just as the tree bursts through the door and disintegrates it with the screwdriver.


The first signal from Guinevere One arrives: a distinctly alien face, which is soon broadcast all over the world. Llewellyn is escorted by Major Blake to the [[Tower of London]], which houses a facility run by the [[United Nations Intelligence Taskforce]]. There, he meets the Prime Minister and her aide, Alex, who tell him that the cover story is that a student in a mask hacked into the television signal. Llewellyn is shaken to realize that extraterrestrial life does exist, and that both the British government and the United Nations are aware of this. A technician, Sally Jacobs, explains that the signal did not come from Mars but 5000 miles above the planet's surface, which means that there is a ship, and it is moving rapidly towards Earth.
He then strides outside the flat to see who was remotely controlling the tree. From ground level, the Santas stare up at the Doctor, but [[transmat]] away when he threateningly points the sonic screwdriver at them. The Doctor calls them "[[pilot fish]]" before collapsing in pain: he is still regenerating, and the energy leaking from him has attracted the "pilot fish"'s attention. He tells them he is having a [[neural implosion]] because they woke him up too soon, but Jackie keeps interrupting with a stream of increasingly unhelpful suggestions until the Doctor tells her to shut up. He grips Rose, warning her that something bigger is coming, then loses consciousness again.


As Rose and Mickey use his laptop to monitor UNIT's readings, the aliens send another signal. The aliens speak in their own language, but Rose does not understand it. Normally, the TARDIS would translate it for her, but it seems that with the Doctor unconscious, that function is not working.

The first signal from ''Guinevere One'' arrives on television: a snarling alien face, which is soon broadcast all over the world. Llewellyn is escorted by [[Blake (The Christmas Invasion)|Major Blake]] to the [[Tower of London]], which houses an underground facility run by [[UNIT]]. There, he meets the Prime Minister and her aide, [[Alex (The Christmas Invasion)|Alex]], who tells him that they're putting out a temporary cover story that students in masks hacked into the television signal. Llewellyn is shaken to realise that extraterrestrial life does indeed exist and that both the [[British]] government and the [[United Nations]] are aware of this. A technician, [[Sally Jacobs]], explains that the signal did not come from [[Mars]] but 5000 miles above the planet's surface, which means that there is a ship, and it is moving rapidly towards Earth.


At UNIT, Blake orders the use of translation software. With no sign of the Doctor, Jones asks Blake about "[[Torchwood Institute|Torchwood]]". She knows that she is not supposed to know about them — not even the [[United Nations]] knows — but she wants them to be ready.
As Rose and Mickey use his laptop to access the [[UNIT website]] and monitor their readings, the aliens send another signal to Earth. They speak in a language that Rose does not understand; normally, the TARDIS would translate it for her, but it seems that with the Doctor unconscious, that function is not working. Rose examines the bedridden Doctor and finds one of his hearts has stopped, meaning he is too injured to be of use and may die if they attempt to wake him again. Back at UNIT, Blake orders the use of translation software. With no sign of the Doctor, Jones asks Blake about [[Torchwood Institute|Torchwood]]. She knows that she is not supposed to know about them – not even the United Nations knows — but she wants them to be ready.


The software rather imprecisely translates the message. The aliens are the [[Sycorax]], and they are claiming the planet as their own, demanding surrender or "they" will die. Their word for "human" also appears to be similar to that of "cattle", temporarily baffling UNIT. Jones declines to surrender, warning the Sycorax that the planet is armed. As dawn rises over London, the Sycorax respond. With a wave of the leader's hand, blue energy sweeps over a third of the world's population, mesmerising them. The mind-controlled people, Sally Jacobs amongst them, climb to the highest spots they can find (primarily the roofs of buildings), and stand at the edge, poised to jump.
The software translates the message: the aliens are called the [[Sycorax]], and they are [[Sycorax invasion of Earth|claiming the planet as their own]], demanding surrender or "they" will die. Their word for "human" also appears to be similar to that of "cattle", temporarily baffling UNIT. Jones declines to surrender, replying to the Sycorax with a warning that the planet is armed. As dawn rises over London, the Sycorax enact their first move. With a wave of the leader's hand, blue energy sweeps over a third of the world's population, mesmerising them. The mind-controlled people, Sally Jacobs amongst them, then climb to the highest spots they can find, primarily the roofs of buildings, and stand at the edge, all of them poised to jump.


Checking the UNIT staff's medical records, Llewellyn discovers that all the affected people have [[blood type|A+ blood]]. The Sycorax found the sample of A+ blood that was sent with other materials on Guinevere One to identify the human race in case of alien contact, and are somehow using that as a control mechanism. Desperate now, Jones gives an emergency broadcast on television, pleading for the Doctor's help if he is out there. She also informs the public that the [[Queen's Christmas speech]] has been cancelled because the [[British Royal Family|Royal Family]] are "on the roof".

Driven to despair by the Doctor's comatose state, Rose breaks down in tears in Jackie's arms.


Just then, the shockwave of the Sycorax ship entering the atmosphere shatters windows all over the city; the gigantic craft takes position above the centre of London as the frightened population watch. Rose, driven to despair by the Doctor's comatose state and not knowing what else to do, asks Mickey and Jackie to help move the Doctor to the safety of the TARDIS. Jackie gathers food and other supplies, including a [[vacuum flask|thermos flask]] of [[tea]].

Just then, the shockwave of [[Fire Trap|the Sycorax ship]] entering the atmosphere shatters windows all over the city; the gigantic craft takes position above the Houses of Parliament and an under-reconstruction Big Ben as the frightened population watch. Rose, not knowing what else to do, asks Mickey and Jackie to help her move the Doctor to the safety of the TARDIS. Jackie gathers food and other supplies, including a thermos flask of [[tea]].


The Sycorax transmat Jones, Alex, Blake and Llewellyn up to their ship. The [[Sycorax leader]] removes his helmet, revealing a skinless face surrounded by a mantle of bone. His hand hovering over a large glowing button, he demands immediate surrender, or he will order the controlled humans to jump. Llewellyn tries to reason with the Sycorax, but is reduced to a pile of bones by the leader's energy whip, as is Blake when he protests. Half of the world will be sold into slavery or a third will die; it is Jones's choice.
The Sycorax teleport Jones, Alex, Blake and Llewellyn up to their ship, where the [[Fadros Pallujikaa (The Christmas Invasion)|Sycorax leader]] removes his helmet, revealing a skinless face surrounded by a mantle of bone.

Llewellyn tries to reason with the Sycorax but is reduced to a pile of bones by the leader's [[Death whip|energy whip]], as is Blake when he protests. The choice is left to Jones; half of the world will be sold into slavery or a third will die.


As Rose and Mickey move the Doctor into the console room, Jackie goes back to get more supplies. Rose, having apparently given up, broods by the console as Mickey tries to use the TARDIS scanner to tune into what is happening; but the time machine's advanced technology is detected by the Sycorax. Outside, Jackie watches helplessly as the TARDIS is transmatted up. Not realising that they are aboard the Sycorax ship, Rose steps out of the TARDIS, and screams when she sees the aliens. Mickey rushes out after her, dropping the flask of tea, which spills and starts dripping through the grilles at the base of the console next to the Doctor's unconscious form. He breathes in the fumes created as the tea sparks against various components.

The Doctor breathes in the subsequent fumes as the tea sparks against various components.


Rose tries to bluff the Sycorax by quoting various things and races she has encountered on her travels, commanding them to leave, but is answered with laughter. The Sycorax leader taunts her attempts to pass off second-hand knowledge as authority, but as he gloats, his alien words start turning into English. Rose realises that the TARDIS translation is working again, and as the Doctor must be conscious for it to be active, that can mean only one thing: the Doctor is awake. On cue, the doors of the police box open and the Doctor stands there, smiling as he says, "Did you miss me?"
Reunited with Harriet Jones, Rose tries to bluff the Sycorax by citing various things and races she has encountered on her travels, commanding them to leave, but is answered with laughter. The Sycorax leader taunts her attempts to pass off second-hand knowledge as authority... but as he gloats, his alien words start being replaced with English. Rose realises that the TARDIS translation ability is working again, and since the Doctor must be conscious for it to be active, that can mean only one thing: the Doctor is awake. On cue, the Doctor emerges from the TARDIS in Howard's dressing gown, smiling as he says, "Did you miss me?"


Easily deactivating the Sycorax leader's energy whip and breaking his staff, the Doctor bluntly tells the alien to wait while he gets more important things out of the way; namely, getting reacquainted with his friends. Disappointed at not being "ginger" (red haired), and somewhat annoyed at Rose's speed in giving up on him, he tells them that all he needed was a "good cup of tea; a superheated infusion of radical (chemistry) free radicals and tannin. Just the thing for healing the [[synapses]]." As the Sycorax leader demands to know who he is, the Doctor blithely strides across the ship's floor, nattering on cheerfully and still working out what his personality is like in this new incarnation. He walks up to the glowing button, discovers that it is powered by blood, and quickly deduces about the blood control. The Doctor tells the leader that in his unstable state, when he sees a large glowing button he just cannot help himself — and to everyone's shock, pushes it.

As the Sycorax leader demands to know who he is, the Doctor blithely strides across the ship's floor, nattering on cheerfully and still working out what his personality is like in this new incarnation. He walks up to the glowing button, discovers that it is powered by A-positive human blood, and quickly [[deduce]]s that the Sycorax are using [[blood control]] — they're controlling all the humans with A-positive blood. The Doctor tells the leader that in his unstable state, when he sees a large glowing button he just cannot help himself — and to everyone's shock, he pushes it.


However, instead of sending the possessed crowds on Earth to their deaths, it simply releases them from the Sycorax control. The Doctor explains that blood control is like [[hypnosis]]: you cannot hypnotise a person to death as the survival instinct is too strong. The Sycorax were bluffing, and the Doctor merely called them on it. The leader says that they can still conquer Earth with an armada, but the Doctor demands that the humans be left alone (quoting part of "The Circle Of Life" from The Lion King in the process), challenging the leader to single combat for the planet.

The Doctor explains that blood control is like [[hypnosis]]: "you can hypnotise someone to cluck like a chicken or sing like [[Elvis]], but you can't hypnotise them to death. Survival instinct's too strong." The Sycorax were bluffing, and the Doctor called them on it. The leader says that they can still conquer Earth by force with an armada, but the Doctor demands that the humans be left alone (quoting part of "The Circle of Life" from ''The Lion King'' in the process), challenging the leader to single combat for the planet.


The swordfight goes from inside the ship to its exterior, but the Doctor is clearly disadvantaged, and in the midst of it, the leader cuts the Doctor's hand off. However, the Doctor is still in the first 15 hours of his regeneration cycle, and regrows his hand, which allows him to gain an advantage over the Sycorax leader and triumph. Holding the leader at sword point at the ship's edge, the Doctor extracts an oath from the leader to leave the planet and never return, in return for the Doctor sparing his life. As the Doctor walks back, celebrating his victory with Rose, the leader tries a final attack whilst the Doctor's back is turned, but the Doctor calmly bounces a satsuma he finds in Howard's dressing gown off a control button, opening a section of the ship's wing beneath the leader, sending the alien plunging to his death. The new Doctor is not a man willing to grant second chances.
The Doctor goads the leader into the fight by insulting him in his native Sycoraxic. The swordfight ranges from inside the ship to its exterior; in the midst of it, the leader cuts the Doctor's hand off, and it falls to the city below along with his sword. The leader assumes the Doctor will yield as he's been "disarmed". But while his friends are horrified, the Doctor is calm; he notes that he is still within the first fifteen hours of his regeneration cycle. Grinning, he explains that there's enough leftover [[Regeneration energy|energy]] after the change to rectify any anomalies or missing bits; and his hand regrows.


The Doctor sends the other Sycorax on their way with a reminder that the planet Earth is defended. [[Teleportation|Transmatted]] back to London, Jones asks if there are more aliens out there and the Doctor notes that there are thousands; the human race is being noticed more and more. As Jones ponders this, visibly troubled, Alex receives a telephone call and quietly informs Jones that Torchwood is ready. Jones seems reluctant, but nevertheless gives the order to fire. Five green beams converge as one over London, and the resulting energy burst destroys the Sycorax ship as it heads into space.
Grabbing a new sword, the Doctor notes "This new hand, it's a fightin' hand!" and reengages the leader in battle, ultimately winning the duel. The Doctor pins the leader to the edge of the ship with his sword, commanding him to leave the planet and never return in exchange for sparing his life. As the Sycorax leader appears to yield and the Doctor walks back to celebrate his victory with Rose, he attempts a final attack whilst the Doctor's back is turned. In response, the Doctor calmly bounces a [[satsuma]] he finds in Howard's dressing gown off [[Kojux-flap|a control button]], opening a section of the ship's wing beneath the leader, sending the alien plunging to his death. With a now-grim expression, the Doctor declares he is a man who doesn't give second chances.


The Doctor glares at Jones, furious, but she tries to justify the use of the weapon (engineered from a crashed spaceship ten years previously) as defending the planet, especially since the Doctor cannot be there all the time. The Doctor bitterly says he should have warned the Sycorax to run as the real monsters, the humans, are coming. When Jones asks if she should consider the Doctor another alien enemy, the Doctor warns her that he can bring down her government with just six words. He whispers them in Alex's ear: "Don't you think she looks tired?"
The Doctor sends the other Sycorax on their way with a reminder that the planet Earth is defended, and he and his human friends are [[Teleportation|transmatted]] back to London to reunite with Jackie. Jones asks the Doctor if there are more aliens out there, and he confirms that there are thousands; the human race is being noticed more and more and it is something they will have to get used to. As Jones ponders this, visibly troubled, Alex receives a telephone call and quietly informs Jones that Torchwood is ready. Jones appears reluctant, but nevertheless gives the order to fire. The Doctor and his friends watch in shock as [[Jathaa sunglider laser|five green beams converge into one over London]], and the resulting energy burst destroys the Sycorax ship as it heads into space.
[[File:Don't you think she looks tired?.jpg|thumb|left|The [[Tenth Doctor]] asks [[Alex Klein|Alex]], "Don't you [[Thought|think]] [[Harriet Jones|she]] looks tired?"]]
The Doctor is furious with Jones, but the Prime Minister tries to justify the use of the weapon (engineered from a crashed spaceship ten years previously) as defending the planet. She tells him how Llewellyn and Blake were mercilessly killed in front of her while the Doctor was asleep, making her realise he cannot be there all the time. The Doctor bitterly retorts he should have warned the Sycorax to run, as the real monsters, the humans, are coming. When Jones asks if she should consider the Doctor another alien enemy, the Doctor warns her that he can bring down her government with just six words, which he whispers into Alex's ear: "Don't you think she looks tired?" Alex gives Jones a startled look, and she demands to know what the Doctor just said, growing frantic in her attempts. Everyone else leaves without a word, and Jones can only apologise quietly.


Jackie, Mickey and Rose serve Christmas dinner in the flat. The Doctor looks through the TARDIS wardrobe, finally settling on a brown pinstripe suit and a long brown coat. He joins the others for dinner, and they watch Harriet Jones on the television, fending off rumours about her ill-health and a pending [[Motion of no confidence|vote of no confidence]] in the [[British House of Commons|House of Commons]]. Outside, what looks like snow is falling over London, accompanied by shooting stars, but the Doctor points out that it is, in fact, ash — the remains of the Sycorax spaceship. It is a new start for Earth, however; with so many people seeing the Sycorax ship, there is no covering up the existence of aliens this time.

But there are new worlds to see and explore. With a now-trusting Rose by his side and eager to continue their travels, the Doctor looks up into the sky to choose a star for their next destination, assuring her that it will be, in the words of [[Ninth Doctor|his previous incarnation]], "fantastic".

|Note=With ''The Christmas Invasion'' came an explosion in the number of people regularly credited on ''Doctor Who''.  In particular, the art department got much more specific crediting than had ever been the case in series 1.  This trend of expanding the number of art department personnel credited would continue right through to series 5, with each series regularly crediting a few more positions. 
<!--There are note variables from Note2 to Note20, but these are probably only necessary for the odd case of "The End of Time".  This set of variables are the only ones which aren't automatically linked; it's just a freeform note field.  All Notes mass together in a single paragraph at the end of the table created by this template.  Thus, each individual note should be a full sentence ending with a period, and should have any links enclosed in [[brackets]].

==Story Notes==
=== Species ===
* Before this episode was broadcast, a fictional tie-in website for the [http://www.guinevere.org.uk Guinevere One] project was created and launched by the [[British Broadcasting Corporation|BBC]]. The site includes an introduction by Harriet Jones and an interview with the project director, [[Professor]] [[Daniel Llewellyn]]. The site claims that the probe was developed by the [[British Rocket Group]]. The organisation's logo partially appears in this episode, in the televised press conference with Professor Llewellyn. The name of the organisation was first mentioned in ''[[Remembrance of the Daleks]]'' and is a reference to the British Experimental Rocket Group from the ''[[Bernard Quatermass|Quatermass]]'' science fiction serials of the 1950s. David Tennant previously starred in the 2005 BBC remake of ''[[Wikipedia:The Quatermass Experiment|The Quatermass Experiment]]'' as Doctor Gordon Briscoe.
* [[Dalek]]s, [[Slitheen]], and the [[Gelth]] are all mentioned by Rose.
* Just before the opening credits sequence, Jackie says the line "Doctor? Doctor who?", continuing a long-running in-joke.
* The weapon fired at the Sycorax was taken from a [[Jathaa]] sunglider.
* The Tenth Doctor speaks with an accent similar to Rose's but unlike the Ninth Doctor's Northern one. In a radio interview broadcast on 23 December [[2005]], Tennant explained that a line of dialogue had been scripted for this episode which explained that the newly regenerated Doctor had imprinted on Rose's accent, "like a chick hatching from an egg," but the line was deleted from the final episode.
* The first shot in this episode, in which the [[Earth]] and its [[the Moon|moon]] appear, is reused footage and was originally the opening shot from "[[Rose (TV story)|Rose]]".
* According to press reports released before this episode was broadcast, producer [[Russell T Davies]] stated that he believed Christmas specials should include traditional Christmas items such as sleigh bells, snow, reindeer, and [[Santa Claus|Santa]].
* The song being played by the Santa Claus band which attacks [[Rose Tyler|Rose]] and [[Mickey Smith|Mickey]] is "[[God Rest Ye Merry, Gentlemen]]."  This song is traditionally associated with the story, ''[[A Christmas Carol]]'', written by [[Charles Dickens]], whom [[the Doctor]] and Rose met in ''[[The Unquiet Dead]]''. The song shares its melody with the "Venusian Lullaby" the [[Third Doctor]] sang in [[DW]]: ''[[The Dæmons]]'' and ''[[The Curse of Peladon]]''. The carol would be heard again in [[DW]]: ''[[The Next Doctor]]''.
* Another song featured in this episode is "[[Song for Ten]]", an original composition by [[Murray Gold]] sung by Tim Phillips. The next two Christmas specials included an original song on the soundtrack. The Phillips version of the song was very brief, and when the time came to compile a soundtrack album, new lyrics were written for the song (reflecting the events of ''[[Doomsday]]'') and it was recorded by Neil Hannon. "Song for Ten" is the first original song commissioned for ''Doctor Who'' since "[[The Ballad of the Last Chance Saloon]]" appeared in the 1966 serial, ''[[The Gunfighters]]''.
* [[David Walliams]] and Bill Nighy were considered for the role of the Tenth Doctor.
* The original choice for the role of the Tenth Doctor was an unknown (and unnamed by the BBC) English actor who spoke in cockney accent, he didn't get the role because he moved with his family to Australia.


===Ratings===
=== Time Lords ===
''to be added''
* While suffering from post [[regeneration]] stress, the Doctor says that he is "having a [[neuron implosion]]." Later, in reference to the cure for this malady, he mentions synapses.


===Myths===
=== Torchwood ===
* Some early reports suggested that the enemy would be the [[Cybermen]]. Tabloid newspaper [[Wikipedia:The Sun|''The Sun'']] reported that [[Shaun Dingwall]] would return as [[Rose Tyler|Rose]]'s father, [[Pete Tyler]], and that this episode would be set on an alternate [[Earth]]. However, all of these claims were proven to be incorrect when the episode was broadcast, and appear to refer to [[Rise of the Cybermen]]/[[The Age of Steel]]. Coincidentally, the Cybermen were later announced as the enemies in the later 2008 Christmas special. 
* This is the first time the [[Torchwood Institute]] is acknowledged to exist as a physical entity; it was first mentioned during ''[[The Weakest Link]]'' game on the [[Satellite Five|Game Station]]. It is so secret even the [[United Nations]] does not know of its existence, and the [[Prime Minister]] isn't supposed to know, although [[Harriet Jones]] somehow does.
* After the announcement that [[Christopher Eccleston]] would leave after the first series, there were erroneous reports that the regeneration was to take place during the Christmas special, not during ''The Parting of the Ways''. ''This may have been an intentional red herring in order to maintain at least some element of surprise for the series finale given that the media had blown Russell T Davies' plan for a surprise regeneration.''


====Influences====
=== United Nations Intelligence Taskforce ===
* Besides being the name of the invading [[alien]]s, [[Sycorax]] is also the name of the [[witch]] in [[William Shakespeare|Shakespeare's]] play, ''[[Wikipedia:The Tempest|The Tempest]]''. In the later [[Series 3 (Doctor Who)|series 3]] episode, ''[[The Shakespeare Code]]'', the Doctor accidentally gives Shakespeare the name "Sycorax" when he sees an animal skull which reminds him of one of the aliens.
* [[UNIT]] has a headquarters in the [[Tower of London]].


* The Sycorax, with their curse-like blood control technology and bone-motif costumes, are slightly similar to [[Faction Paradox]], a time-travelling voodoo cult created by [[Lawrence Miles]] that were recurring villains in the [[BBC Eighth Doctor Adventures]] novels.
=== Technology ===
* The [[Hubble Array]] is following the course of the Sycorax ship.


* [[Guinevere One]], the name of the probe that Earth sends to [[Mars]], references the myths of legend [[King Arthur]]. In those stories, Guinevere was Arthur's Queen consort. Her name is an old French form of the Welsh name Gwenhwyfar, which can be translated as "white shadow". Her adulterous affair with Arthur's chief knight, [[Wikipedia:Lancelot|Lancelot]], and betrayal of her husband lead to the downfall of their kingdom.
== Notes ==
* This is the first ''Doctor Who'' episode clearly labelled as a [[Christmas special]]. The seventh episode of ''[[The Daleks' Master Plan (TV story)|The Daleks' Master Plan]]'', titled "[[The Feast of Steven]]", was written as a Christmas episode and was first broadcast on [[25 December (releases)|25 December]] [[1965 (releases)|1965]].
* This is the first episode of the 2005 revival of ''Doctor Who ''to air on a Sunday in the UK.
* [[David Tennant]] is credited as "The Doctor", as opposed to [[Christopher Eccleston]] who was credited as "Doctor Who". The change in the credit was done at Tennant's request.
** This occurrence parallels [[Peter Davison]]'s request for an identical change in credit when he succeeded [[Tom Baker]]. Like Tennant, [[Castrovalva (TV story)|Davison's first episode]] would begin this new billing.
** This story was effectively the first since 1989's ''[[Survival (TV story)|Survival]]'' to credit the role as "The Doctor".
* The "middle eight" section of [[Doctor Who theme|the theme tune]] is restored in this episode and is heard for the first time in the revived series.
* Before this episode was broadcast, a tie-in website for the ''Guinevere One'' project was created and launched by the [[BBC]]. The site includes an introduction by Harriet Jones and an interview with the project director, [[Professor]] [[Daniel Llewellyn]]. The site claims that the probe was developed by the [[British Rocket Group]]. The organisation's logo partially appears in this episode, in the televised press conference with Professor Llewellyn. The name of the organisation was first mentioned in ''[[Remembrance of the Daleks]]'' and is a reference to the British Experimental Rocket Group from the ''[[Bernard Quatermass|Quatermass]]'' science fiction serials of the 1950s. David Tennant had previously starred in [https://en.wikipedia.org/wiki/The_Quatermass_Experiment_(film) the 2005 BBC live remake] of {{wi|The Quatermass Experiment (2005)|The Quatermass Experiment}} as Doctor Gordon Briscoe, and Quatermass' first line to Briscoe was changed by actor [[Jason Flemyng]] during the broadcast from "Good to have you back, Gordon" to "Good to have you back, ''Doctor''" — Tennant's casting as the Doctor was announced two weeks after ''Quatermass'' went to air, and his castmates would have been aware of the speculation during rehearsals.
* Immediately following this episode, ''[[Attack of the Graske (video game)|Attack of the Graske]]'', an interactive mini-episode starring David Tennant, was made available on the [[BBC Red Button]].
* Just before the opening credits sequence, Jackie says the line, "Doctor? Doctor who?", continuing a long-running in-joke. Unlike many instances of the joke, however, the line primarily plays as a genuine question, since she has never before met the [[Tenth Doctor]] and knows nothing of [[regeneration]].
* The Tenth Doctor speaks with an accent similar to Rose's but unlike the [[Ninth Doctor]]'s Northern one. In a radio interview broadcast on 23 December 2005, [[David Tennant]] explained that a line of dialogue had been scripted for this episode which explained that the newly regenerated Doctor had imprinted on Rose's accent, "like a chick hatching from an egg", but the line was deleted from the final episode. This concept would later be added back into the [[The Christmas Invasion (novelisation)|novelisation]].
* The opening shot of this episode, in which the Earth and its moon appear, is reused footage from the opening shot of the episode ''[[Rose (TV story)|Rose]]''.
* The song being played by the Santa Claus band which attacks Rose and Mickey is "[[God Rest Ye Merry, Gentlemen]]". This song is traditionally associated with the novel ''[[A Christmas Carol]]'', written by [[Charles Dickens]], whom [[the Doctor]] and Rose met in ''[[The Unquiet Dead (TV story)|The Unquiet Dead]]''. The song shares its melody with the "Venusian Lullaby" the [[Third Doctor]] sang in ''[[The Dæmons (TV story)|The Dæmons]]'' and ''[[The Curse of Peladon (TV story)|The Curse of Peladon]]''. The carol can be heard again in ''[[The Next Doctor (TV story)|The Next Doctor]]''.
* Another song featured in this episode is "[[Song for Ten]]", an original composition by [[Murray Gold]] sung by [[Tim Phillips]]. The next two Christmas specials included an original song on the soundtrack. The Phillips version of the song was very brief, and when the time came to compile a soundtrack album, new lyrics were written for the song (reflecting the events of ''[[Doomsday (TV story)|Doomsday]]'') and it was recorded by [[Neil Hannon]]. "Song for Ten" is the first original song commissioned for ''Doctor Who'' since the untitled rap song for the [[Ringmaster]] heard during the 1988 story ''[[The Greatest Show in the Galaxy (TV story)|The Greatest Show in the Galaxy]]''.
* One of the outfits considered by the Doctor in the wardrobe is the costume worn by [[David Tennant]] in his previous role as [[Casanova]] in {{w|Casanova (2005 TV serial)|the eponymous television serial}}.
* This marks the first time in the new series that any room in the TARDIS other than the console room is seen on-screen.
** It is also the only appearance in the first [[Russell T Davies]] era of an area of the TARDIS outside of the console room.
* In a scene filmed for the episode, but deleted before broadcast (though included on the DVD), the Doctor attempts to utter his predecessor's catchphrase, "Fantastic!" but due to his "new teeth" (ref. his comments at the end of ''[[The Parting of the Ways (TV story)|The Parting of the Ways]]'') finds it initially impossible to do so. This scene was intended to set up the final scene of the episode in which the new Doctor finally utters the word, "Fantastic!"
* ''The Christmas Invasion'' can be viewed in its entirety on the BBC America website.
* A signal intrusion incident that occurred in [[Chicago]] during an airing of the [[Fourth Doctor]] serial ''[[Horror of Fang Rock (TV story)|Horror of Fang Rock]]'' is referenced by Harriet Jones' aide Alex when he says the official story of the Sycorax appearing via the probe is because of "a mask, some sort of prosthetic. Students hijacking the signal."
* This was the first time a television drama was permitted to film atop the Tower of London.<ref>http://www.bbc.co.uk/blogs/doctorwho/entries/2bf7eea9-a575-4947-8698-8cdcb7386518</ref>
* This is the first episode to use music performed by the BBC National Orchestra Of Wales, in contrast to all previous episodes of the revived series which used a computer-created soundtrack.
* Harriet Jones states that the laser that destroyed the Sycorax was taken from technology of a ship that crashed a decade ago, placing the time of the crash in [[1996]].
* [[Russell T Davies]] wrote the script with the [[Ninth Doctor]] in mind, the idea being that the characteristics of the Tenth Doctor would emerge more through [[David Tennant]]'s portrayal than from scripted lines.
* At one stage, the Sycorax were assisted by an ill-fated civil servant called Sir Aubrey. Having destroyed [[Big Ben]] in ''[[Aliens of London (TV story)|Aliens of London]]'', [[Russell T Davies]] considered a scene in which the Sycorax spaceship decimated the newly-rebuilt structure, leading to Sir Aubrey's death beneath the falling rubble. Instead, he decided to demolish a much more modern London landmark: [[the Gherkin]].
* The TARDIS wardrobe contains a Hogwarts uniform. [[David Tennant]] was fresh off his appearance as [https://harrypotter.fandom.com/wiki/Bartemius_Crouch_Junior Barty Crouch Jr.] in ''[https://en.wikipedia.org/wiki/Harry_Potter_and_the_Goblet_of_Fire_(film) Harry Potter and the Goblet of Fire]''.
* The prototype of the Sycorax swords was auctioned on eBay to raise funds for the [[Great Ormond Street Hospital]] Children's Charity. It raised £920.51.
* [[Phil Collinson]] was fond of Harriet Jones, and he argued against her downbeat fate, which was partly fuelled by the sense of betrayal [[Russell T Davies]] felt towards [[Tony Blair]].
* The ''Guinevere 1'' probe was inspired by the ''[https://en.wikipedia.org/wiki/Beagle_2 Beagle 2]'', a British-made spacecraft which landed on the surface of [[Mars]] on [[Christmas Day]] [[2003]]. Sadly, the malfunction of its solar panels prevented the ''Beagle 2'' from establishing contact with its operators on Earth, and the mission was deemed a failure. Davies also remembered the first pictures sent from Mars by the ''[https://en.wikipedia.org/wiki/Viking_1 Viking 1]'' lander in [[July]] [[1976]], and he wanted the ''Guinevere 1'' to transmit something more exciting than the empty, bleak Martian landscape.
* Because the [[United Nations]] had reacted unfavourably to a UNIT website set up by the BBC to help promote [[Series 1 (Doctor Who 2005)|Season One]], [[Russell T Davies]] decided to refer to UNIT by the acronym only.
* Two of the blood-controlled children were named after [[Russell T Davies]]' nephew and niece, Jonathan and Catrin.
* Some consideration was given to moving to high-definition recording, but it was ultimately decided to retain the Digital Betacam format used during [[Series 1 (Doctor Who 2005)|Series 1]].
* During the four months which had elapsed since filming wrapped on ''[[Bad Wolf (TV story)|Bad Wolf]]/[[The Parting of the Ways (TV story)|The Parting of the Ways]]'', [[Billie Piper]] had adopted a noticeably shorter hairstyle, not realising that the events of the special would occur in its immediate aftermath. As a result, it was decided that she would wear hair extensions for the holiday special.
* [[Freema Agyeman]] auditioned for the role of Sally Jacobs, but the production team felt that she was deserving of a more prominent role. She would later play [[Adeola Oshodi]] in ''[[Army of Ghosts]]'' before landing the role of [[Martha Jones]].
* [[Peter Davison]] visited filming at the Brandon Estate.
* Torrential rain prevented some of the Powell Estate sequences from being completed in London. They were instead taped at Loudoun Square in Cardiff.
* For the interior of the Sycorax ship, [[Russell T Davies]] wanted to avoid a traditional metallic spacecraft. As such, these scenes were recorded at Clearwell Caves in [[Gloucestershire]].
* [[Russell T Davies]] hoped to reprise a shot originally intended for ''[[Rose (TV story)|Rose]]'', tracking from outside the TARDIS, through the doors and into the console room to reveal the revived Doctor. Unfortunately, these plans had to be abandoned due to the difficulty of transporting the motion-capture equipment into the caves.
* The overall pace of the Gloucestershire work was very slow, hampered by both the technological limitations imposed by the environment and [[Sean Gilder]]'s difficulties with the contact lenses he wore as the Sycorax Leader. This forced an additional day at Clearwell Caves.
* It was originally thought that the swordfight between the Doctor and the Sycorax Leader on the wing of the spaceship would be performed on the roof of a tall building in Cardiff. However, [[James Hawes]] could not find a venue which obscured the surrounding conurbation, and so the sequence was instead filmed against an unobstructed view of the sea at the docks in Barry.
* Originally, [[Russell T Davies]] had hoped to emphasise the global threat of the Sycorax by including scenes of blood-controlled humans near [[Pyramid|the pyramids]] and on [[Sydney Harbour Bridge]]. However, neither shot could be realised convincingly, and they were both dropped.
* A deleted scene saw the Tenth Doctor realising that his predecessor's “Fantastic!” catchphrase no longer suited him.
* The concluding scene initially saw the Doctor and Rose ruminating on how they missed [[Ninth Doctor|the Ninth Doctor]], but the production team felt that the special should be looking to the future in its closing minutes, rather than reflecting on the past.
* To accompany the scene of the Doctor in the TARDIS wardrobe, [[Russell T Davies]] originally wanted to use the [[1963]] version of "[https://en.wikipedia.org/wiki/The_Bells_of_St._Mary%27s_(song) The Bells of St Mary's]" by [https://en.wikipedia.org/wiki/Bob_B._Soxx_%26_the_Blue_Jeans Bob B Soxx & the Blue Jeans]. When the rights proved prohibitively expensive, [[Murray Gold]] was instead asked to create an original tune. The result was "[[Song for Ten]]".


* [[The Doctor]]'s sword duel with the Sycorax leader, particularly when his hand is cut off, suggests the lightsaber duel between [[Wikipedia:Luke Skywalker |Luke Skywalker]] and [[Wikipedia:Darth Vader |Darth Vader]] in "[[Wikipedia:The Empire Strikes Back|The Empire Strikes Back]]."
=== Ratings ===
* 9.84 million<ref>[http://www.doctorwhonews.net/2018/10/the-woman-who-fell-to-earth-tops-charts.html Doctor Who ratings]</ref>


* The Doctor comments that the bathrobe and pajamas [[Jackie Tyler|Jackie]] has given him to wear are "very [[Arthur Dent]]." Arthur Dent is a character in ''[[The Hitchhiker's Guide to the Galaxy]]'', created by former ''[[Doctor Who]]'' [[script editor]] [[Douglas Adams]]. The Doctor's mention of Arthur as a "nice man", suggesting he has actually met him, together with the fact that the book the [[Fourth Doctor]] reads in "[[Destiny of the Daleks]]" is written by author [[Oolin Coluphid]] raises the question of how much of the characters and events set in the Guide stories also occur in the [[Doctor Who Universe]].
=== Myths ===
* Some early reports suggested that the enemy would be the [[Cybermen]]. Tabloid newspaper ''[[The Sun (newspaper)|The Sun]]'' reported that [[Shaun Dingwall]] would return as [[Rose Tyler|Rose]]'s father, [[Pete Tyler]], and that this episode would be set on an alternative [[Earth]]. However, all of these claims were proven to be incorrect when the episode was broadcast, and appear to refer to ''[[Rise of the Cybermen (TV story)|Rise of the Cybermen]]''/''[[The Age of Steel (TV story)|The Age of Steel]]''. Coincidentally, the Cybermen were later announced as the enemies in [[The Next Doctor (TV story)|the later 2008 Christmas special]].
* After the announcement that [[Christopher Eccleston]] would leave after the first series, there were erroneous reports that the regeneration was to take place during the Christmas special, not during ''The Parting of the Ways''. ''(This may have been an intentional red herring in order to maintain at least some element of surprise for the series finale given that the BBC had accidentally blown Russell T Davies' plan for a surprise regeneration.)''


* When speaking to the Sycorax of the great potential [[human]]s possess, the Doctor realizes he is quoting from ''[[The Lion King]]''.
=== Influences ===
* Besides being the name of the invading [[alien]]s, [[Sycorax]] is also the name of the [[witch]] in [[William Shakespeare]]'s play, ''[[The Tempest]]''. In the later [[Series 3 (Doctor Who 2005)|series 3]] episode, ''[[The Shakespeare Code (TV story)|The Shakespeare Code]]'', the Doctor accidentally gives Shakespeare the name "Sycorax" when he sees an animal skull which reminds him of one of the aliens.
* The Sycorax, with their curse-like blood control technology and bone-motif costumes, are slightly similar to [[Faction Paradox]], a time-travelling voodoo cult created by [[Lawrence Miles]] that were recurring villains in the [[BBC Eighth Doctor Adventures|BBC ''Eighth Doctor Adventures'']] novels.
* Harriet Jones's decision to destroy the Sycorax spaceship, despite the fact it was leaving Earth, echoes [[Margaret Thatcher]]'s decision to sink the Argentinian ship ''[[Belgrano]]'' in the 1982 [[Falklands War]], even though evidence suggests it was actually leaving British waters.
* ''[[Guinevere One]]'', the name of the probe that Earth sends to [[Mars]], references the myths of [[King Arthur]]. In those stories, Guinevere was Arthur's Queen Consort. Her name is an old French form of the Welsh name Gwenhwyfar, which can be translated as "white shadow". Her adulterous affair with Arthur's chief knight, [[Lancelot]], and betrayal of her husband led to the downfall of their kingdom. When the [[Seventh Doctor]] was recognised as [[Merlin]], Arthur's advisor, he assumed that he would later find himself in this role. ([[TV]]: ''[[Battlefield (TV story)|Battlefield]]'')
* The Doctor's sword duel with the Sycorax leader, particularly when his hand is cut off, resembles the [[lightsaber]] duel between [[Luke Skywalker]] and [[Darth Vader]] in ''[[Star Wars]] [[The Empire Strikes Back|Episode V: The Empire Strikes Back]]''.
* The Doctor comments that the bathrobe and pyjamas [[Jackie Tyler|Jackie]] has given him to wear are "very [[Arthur Dent]]". In the short story ''[[Have You Seen This Man? (short story)|Have You Seen This Man?]]'' on the ''[[Who is Doctor Who? (tie-in website)|Who is Doctor Who?]]'' website, a certain Arthur Dent mentions that the Doctor had once laid in front of a [[bulldozer]] in front of Dent's [[Arthur Dent's home|home]], meaning that the reference in ''The Christmas Invasion'' is more this likely referring to this encounter between the characters. Arthur Dent is a character in ''[[The Hitchhiker's Guide to the Galaxy (series)|The Hitchhiker's Guide to the Galaxy]]'', created by former ''[[Doctor Who (TV series)|Doctor Who]]'' [[script editor]] [[Douglas Adams]]. Also, Jackie's line "Anything else he's got two of?" is also spoken by Arthur Dent in the 2005 movie adaptation of ''The Hitchhiker's Guide to the Galaxy'', in reference to the two-headed [[Zaphod Beeblebrox]].
* When speaking to the Sycorax of the great potential [[human]]s possess, the Doctor realises he is quoting from ''[[The Lion King]]''.


* Harriet Jones's response to the [[America]]n President's message, namely that she "is in control of the situation and doesn't want him using this as an excuse to start a war" may be an in-reference to the [[Wikipedia:Iraq War|Iraq War]] and [[Tony Blair]], whose critics have accused him of being a puppet of [[Wikipedia:George W. Bush|George W. Bush]].

===Location Filming===
=== Production errors ===
''to be added''
{{Discontinuity}}
* When Mickey calls Rose to check out the military broadcast of the Sycorax ship, you can see for a split-second the video player playing the broadcast, revealing that it was not green-screened, but a video playing on the computer.
* Although it has been a very short time since the Doctor regenerated, as Rose passes the door of the TARDIS after the Doctor collapses, her hair is visibly longer. ([[TV]]: ''[[The Parting of the Ways (TV story)|The Parting of the Ways]]'') This exposes the several month break between the wrapping up of Series 1 in March 2005, and the beginning of filming for Series 2 in July, during which time Billie Piper allowed her hair to grow longer.
* When proclaiming his new form to be "lucky", the Doctor is facing towards the Sycorax ship, but when mentioning being in the first 15 hours of his regenerative cycle, he is facing away from the Sycorax ship. He is facing the ship again when his hand regrows.
* A lot of the shots between the Doctor winning the challenge and giving his warning to the Sycorax horde have inconsistent lighting. One notable example of this is when the Doctor throws the satsuma, the light is on the right side of his face but is then on the left side of the button the fruit hits when it should be on the right. The green screen of the ship exterior is also darkened on the left side, making this error more prominent.
* In one of the Tower of London scenes, the Guinevere 1 Space Probe is incorrectly spelt "Guinivere 1" on a computer screen.
* In the 2017 Series 2 [[Blu-ray]] [[Steelbook]], Phil Collinson, the producer of this episode, is incorrectly credited after the title sequence as "Phil Collision".


===Discontinuity, Plot Holes, Errors===
== Continuity ==
* Early in this episode, a [[Wikipedia:Routemaster|Routemaster]] bus briefly appears. However, Routemasters were actually removed from active service on 9 December 2005. ''It could have been a heritage service, and maybe routemasters being replaced weren't the main concern in this time-frame, especially when Earth has just had to cover up events such as the Slitheen encounter.''
* The Doctor's speech to PM Harriet Jones about how "[[Earth]] is drawing attention to itself" recalls a similar statement made by [[the Brigadier]] when recruiting [[Liz Shaw]] to UNIT. ([[TV]]: ''[[Spearhead from Space (TV story)|Spearhead from Space]]'')
* It is left unexplained why Britain's space program has apparently reverted to celebrating unmanned probes arriving at Mars when ''[[The Ambassadors of Death]]'' established that by this time Britain had already sent manned missions to Mars. ''There is actually a real-world example of such reversion occurring: America's NASA program sent manned missions to the Moon in the 1960s and 70s yet by the 2000s had reverted to again sending unmanned probes to the moon.''
* Jones's destruction of the Sycorax ship and the Doctor's angry reaction are similar to the third incarnation's outrage when the Brigadier betrays his trust and using explosives to destroy the [[Early Silurian|Silurian]] hibernation chambers of [[Wenley Moor]] during the [[1970s]] out of [[Xenophobia|xenophobic]] [[prejudice]]. ([[TV]]: ''[[Doctor Who and the Silurians (TV story)|Doctor Who and the Silurians]]'')
* After finally recovering, one of the first things the Doctor does is ask Rose about his appearance, despite already having done so in the [[Children in Need Special]]. ''Considering the Doctor's imbalance after his regeneration, he might have forgotten the earlier discussion. Also, she never answered him in the special.''
* The [[United Kingdom]] had previous missions to [[Mars]]. ([[TV]]: ''[[The Ambassadors of Death (TV story)|The Ambassadors of Death]]'', [[PROSE]]: ''[[The Dying Days (novel)|The Dying Days]]'')
*After indicating to Rose how important Harriet Jones becomes to Britain and planet earth ([[DW]]: ''[[World War Three]]''), here he proceeds to sabotage her career. What about his many spiels about his being forbidden to change history? ''Some events can be changed, as established in [[The Fires of Pompeii]]. This must be one of them. In any case, Harriet Jones was to be vital to the world in [[The Stolen Earth]]. In that story, her death was not witnessed by the audience or any of the characters. It remains possible then, that she survived and did eventually serve the two more terms and usher in Britain's Golden Age, as predicted by the Ninth Doctor. Alternatively, it was the Doctor deposing Harriet that lead to [[The Master (Harold Saxon)|the Master]] (another time traveller) to be elected in her place.''
* The [[Ice Warrior]]s are actual Martians - which, as stated, look "completely different". ([[TV]]: ''[[The Ice Warriors (TV story)|The Ice Warriors]]'')
*When the Doctor is choosing his new outfit, you can see the TARDIS doors behind a rack of clothes, although this is meant to be further into the TARDIS. ''This is most likely merely an oversight, they needed to show the TARDIS but probably didn't have the time or money to build a new TARDIS set for such a small shot.''
* While the Tenth Doctor, Rose and Mickey are on the Sycorax ship, Jackie has an unexpected encounter with the Third Doctor, [[Jo Grant]] and Captain [[Mike Yates]], who unintentionally responded to Harriet Jones' distress call after it was detected by the Third Doctor's TARDIS. ([[PROSE]]: ''[[The Christmas Inversion (short story)|The Christmas Inversion]]'')
* While The Tenth Doctor and Rose were away on the Sycorax ship, {{Delgado}} had broken into Jackie's flat, and she defeats him with The Third Doctor, Jo Grant, and Mike Yates. ([[PROSE]]: ''[[The Christmas Inversion (short story)|The Christmas Inversion]]'')
* The Robotic Santas reappear, under control of the [[Empress of the Racnoss (The Runaway Bride)|Empress of the Racnoss]]. ([[TV]]: ''[[The Runaway Bride (TV story)|The Runaway Bride]]'')
* Harriet Jones questions if [[Code Nine]], an [[Emergency Protocols|Emergency Protocol]] which detected important words such as "Doctor" and "TARDIS", had been activated. ([[TV]]: ''[[Aliens of London (TV story)|Aliens of London]]''/''[[World War Three (TV story)|World War Three]]'')
* The Doctor regrows his severed hand as he retains regenerative energy for the first fifteen hours in a new body, suggesting an explanation for [[Romana II]]'s ability to change her appearance several times during her [[regeneration]]. ([[TV]]: ''[[Destiny of the Daleks (TV story)|Destiny of the Daleks]]'')
* The Doctor's severed hand is later retrieved by [[Jack Harkness]]. ([[TV]]: ''[[Everything Changes (TV story)|Everything Changes]]'', ''[[Utopia (TV story)|Utopia]]'') Much later, it would return to the Doctor. ([[TV]]: ''[[Last of the Time Lords (TV story)|Last of the Time Lords]]'') It bubbled furiously when it sensed [[The Doctor's TARDIS|the TARDIS]] flying off to find [[Jenny]]. ([[TV]]: ''[[The Poison Sky (TV story)|The Poison Sky]]'', ''[[The Doctor's Daughter (TV story)|The Doctor's Daughter]]'') After the Doctor used it as a receptacle for regeneration energy, something compelled [[Donna Noble|Donna]] to touch the hand, enabling it to grow into the [[Meta-Crisis Tenth Doctor]] and also turning Donna into the [[Doctor-Donna]], leading them to defeat the [[New Dalek Empire]] and stop [[Davros]]' [[reality bomb]]. The real Tenth Doctor subsequently took the Meta-Crisis Tenth Doctor to [[Pete's World|a parallel universe]], leaving him to live out his life there with [[Rose Tyler]]. ([[TV]]: ''[[Journey's End (TV story)|Journey's End]]'')
* While rummaging his clothes in search of what should be his new look, the Tenth Doctor passes through the [[Second Doctor]]'s [[tartan]] [[trousers]] and [[black]] [[frock coat]], ([[TV]]: ''[[The Power of the Daleks (TV story)|The Power of the Daleks]]''-''[[The War Games (TV story)|The War Games]]'') the [[Sixth Doctor]]'s [[Hawaii]]an [[waistcoat]], ([[TV]]: ''[[The Two Doctors (TV story)|The Two Doctors]]'') and the [[Fourth Doctor]]'s [[crimson]] [[scarf]] with [[violet]] [[purple]] stripes. ([[TV]]: ''[[The Leisure Hive (TV story)|The Leisure Hive]]''-''[[Logopolis (TV story)|Logopolis]]'') In the rest of the wardrobe room, various items and articles of clothing are visible, including:
** A brass pillar. ([[TV]]: ''[[An Unearthly Child (TV story)|An Unearthly Child]]'', et al.)
** A Third Doctor's [[Inverness cape]] hanging next to the pillar. ([[TV]]: ''[[Terror of the Autons (TV story)|Terror of the Autons]]'')
** The [[Sixth Doctor's coat|Sixth Doctor's rainbow frock coat]] on the other side of the pillar. ([[TV]]: ''[[The Twin Dilemma (TV story)|The Twin Dilemma]]'', et al.)
** One of [[Steven Taylor]]'s [[jumpers]] next to the coat. ([[TV]]: ''[[The Celestial Toymaker (TV story)|The Celestial Toymaker]]'')
** A grand mirror. ([[TV]]: ''[[Castrovalva (TV story)|Castrovalva]]'')
** [[Kublai Khan]]'s cane against the mirror. ([[TV]]: ''[[Marco Polo (TV story)|Marco Polo]]'', et al.)
** A wooden trunk ([[TV]]: ''[[The Power of the Daleks (TV story)|The Power of the Daleks]]'')
** The [[Seventh Doctor]]'s [[umbrella]] in a bucket. ([[TV]]: ''[[Time and the Rani (TV story)|Time and the Rani]]'', et al.)
** The Sixth Doctor's umbrella. ([[TV]]: ''[[The Two Doctors (TV story)|The Two Doctors]]'', ''[[Time and the Rani (TV story)|Time and the Rani]]'')
** The [[Fifth Doctor]]'s [[Panama hat]] on this umbrella. ([[TV]]: ''[[Castrovalva (TV story)|Castrovalva]]'', et al)
** The Second Doctor's [[stovepipe hat]] ([[TV]]: ''[[The Power of the Daleks (TV story)|The Power of the Daleks]]'', ''[[The Highlanders (TV story)|The Highlanders]]'', ''[[The Underwater Menace (TV story)|The Underwater Menace]]'')
** The First Doctor's feather hat. ([[TV]]: ''[[The Reign of Terror (TV story)|The Reign of Terror]]'')
** The Fourth Doctor's brown [[fedora]] on the spiral stairs under the room. ([[TV]]: ''[[Robot (TV story)|Robot]]'', et al.)
** [[Alydon]]'s cloak hanging under the room. ([[TV]]: ''[[The Daleks (TV story)|The Daleks]]'')
** A [[Fourth Doctor]]-like outfit, with a long coat and long yellow and red scarf, hanging from the very [[hatstand]] of this incarnation.
** The [[Eighth Doctor]]'s [[forest green]] frock coat. ([[TV]]: ''[[Doctor Who (TV story)|Doctor Who]]'')
** A [[kilt]]. ([[TV]]: ''[[The Highlanders (TV story)|The Highlanders]]'')
* During Rose's improvised speech to the Sycorax, she resorts to name-dropping several creatures from her previous travels with the [[Ninth Doctor]]:
** [[Slitheen-Blathereen family|The Slitheen]] ([[TV]]: ''[[Aliens of London (TV story)|Aliens of London]]''/''[[World War Three (TV story)|World War Three]]'', ''[[Boom Town (TV story)|Boom Town]]'')
** [[Gelth|The Gelth]] ([[TV]]: ''[[The Unquiet Dead (TV story)|The Unquiet Dead]]'')
** [[Mighty Jagrafess of the Holy Hadrojassic Maxarodenfoe|The Mighty Jagrafess]] [sic] ([[TV]]: ''[[The Long Game (TV story)|The Long Game]]'')
** [[Dalek|The Daleks]] ([[TV]]: ''[[Dalek (TV story)|Dalek]]'', ''[[Bad Wolf (TV story)|Bad Wolf]]''/''[[The Parting of the Ways (TV story)|The Parting of the Ways]]'')
* Rose attempts to invoke [[Article 15 of the Shadow Proclamation]]. ([[PROSE]]: ''[[Diamond Dogs (novel)|Diamond Dogs]]'') Presumably, she was attempting to recall [[Convention 15 of the Shadow Proclamation|Convention 15]], which the Ninth Doctor had used to approach the [[Nestene Consciousness]]. ([[TV]]: ''[[Rose (TV story)|Rose]]'')
* The ramifications of the destruction of the Sycorax vessel, including the impact on a group of female (and presumably related) Sycorax, is explored in [[COMIC]]: ''[[The Widow's Curse (comic story)|The Widow's Curse]]''.
** It also indicates that the Sycorax Leader's proclamation of "Fadros Pallujikaa" is actually his name.
* The TARDIS is in motion as it materialises, due to the Doctor speeding it up to breakneck speeds in the time vortex. ([[TV]]: ''[[Born Again (TV story)|Born Again]]'') It has materialised and dematerialised in motion before, ([[TV]]: ''[[Fury from the Deep (TV story)|Fury From the Deep]]'', ''[[The War Games (TV story)|The War Games]]'') and would do so again next Christmas. ([[TV]]: ''[[The Runaway Bride (TV story)|The Runaway Bride]]'')
* Jones' statement regarding the Doctor not always being available to help the planet is later echoed and discussed by [[Gwen Cooper]]. ([[TV]]: ''[[Children of Earth: Day Five (TV story)|Children of Earth: Day Five]]'')
* The Third Doctor was revived from a trance by [[coffee]]. ([[TV]]: ''[[Planet of the Spiders (TV story)|Planet of the Spiders]]'')
* The Doctor identifies the blood type through taste. [[Romana II|Romana]] demonstrated a similar sensory precision in identifying a [[mineral]]'s composition through taste. ([[TV]]: ''[[Destiny of the Daleks (TV story)|Destiny of the Daleks]]'')
* When the Doctor regenerates into the [[Eleventh Doctor]], he complains again when he notices that he's "still not [[Ginger (trait)|ginger]]"; ([[TV]]: ''[[The End of Time (TV story)|The End of Time]]'') the Ninth Doctor previously wondered why he'd never become ginger while examining his reflection. ([[PROSE]]: ''[[Rose (novelisation)|Rose]]'')
* Construction girders around the Clock Tower of [[Big Ben]] indicate that repair work is still being done following its recent collision with a spaceship. ([[TV]]: ''[[Aliens of London (TV story)|Aliens of London]]'')
* The Sycorax would later appear to be part of the [[Pandorica Alliance]]. ([[TV]]: ''[[The Pandorica Opens (TV story)|The Pandorica Opens]]'')
* Harriet Jones introduces herself regularly as "Harriet Jones, Prime Minister" to which the common reply is, "Yes, I know who you are"; she did the same before becoming Prime Minister, introducing herself to everyone as "Harriet Jones, MP for Flydale North". ([[TV]]: ''[[Aliens of London (TV story)|Aliens of London]]''/''[[World War Three (TV story)|World War Three]]'')
** She would later continue this as former Prime Minister, with a similar response. ([[TV]]: ''[[The Stolen Earth (TV story)|The Stolen Earth]]'')
* The Doctor has previously engaged in sword fights. ([[TV]]: [[Marco Polo]], ''[[The Sea Devils (TV story)|The Sea Devils]]'', ''[[The Masque of Mandragora (TV story)|The Masque of Mandragora]]'', ''[[The Androids of Tara (TV story)|The Androids of Tara]]'', ''[[The King's Demons (TV story)|The King's Demons]]'')
* The Doctor previously encountered the Sycorax and [[blood control]] in his [[seventh incarnation]] at [[the Blood Bank]] in the [[far future]]. ([[AUDIO]]: ''[[Harvest of the Sycorax (audio story)|Harvest of the Sycorax]]'')
* By seeding the downfall of Harriet Jones as Prime Minister, the Tenth Doctor unwittingly triggered a cascade of events that would endanger the universe and end with his demise:
** The Doctor and future companion [[Martha Jones]] arrived at [[Malcassairo]] in the year [[100,000,000,000,000]] by accident. They also found that [[Jack Harkness]] hitched onto the TARDIS exterior and was dragged through the [[Time Vortex]], trying to reunite with the Doctor after being left behind at the [[Satellite Five|Game Station]] when he was made [[immortality|immortal]] by the [[Bad Wolf (entity)|Bad Wolf]]. ([[TV]]: ''[[The Parting of the Ways (TV story)|The Parting of the Ways]]'', ''[[Utopia (TV story)|Utopia]]'')
** The group met [[Yana|Professor Yana]], who Martha noticed had a [[Biodata module|fob watch]]. After her experience with the [[chameleon arch]], she thought Yana was a benevolent [[Time Lord]] that became human, but Yana's true identity belonged to the [[War Master]], who had fled the [[Time War]]. After regenerating, he stole the Doctor's TARDIS and fled the planet, but the Doctor tampered with his TARDIS to trap him on Earth. ([[TV]]: ''[[Human Nature (TV story)|Human Nature]]'', ''[[Utopia (TV story)|Utopia]]'')
** Jones' removal from power allowed {{Simm}} to replace her under the identity of Harold Saxon, though he was later removed from power and shot by [[Lucy Saxon]] for tormenting her. He chose to die rather than regenerate into a new incarnation and live a life of captivity. ([[TV]]: ''[[The Sound of Drums (TV story)|The Sound of Drums]]'', ''[[Last of the Time Lords (TV story)|Last of the Time Lords]]'')
** The [[Disciples of Saxon]], the Master's followers, resurrected him, but Lucy again tried to kill him and managed to damage his new body at the price of her own life. The crippled Master was soon recruited by [[Joshua Naismith]] to work on the [[Immortality Gate]] for his intellect. The Master sabotaged the Gate and used it to make the [[Master Race]], then retrieved [[Gallifrey]] and its denizens from the Time War with the help of a [[White-Point Star]]. ([[TV]]: ''[[The End of Time (TV story)|The End of Time]]'')
** During the Master's confrontation with [[Lord President]] [[Rassilon]], [[Wilfred Mott]] rescued a trapped worker in the Gate's radiation booth and took his place. The booth's anti-leak security measures only allowed one person to exit while another person had to be locked inside. ([[TV]]: ''[[The End of Time (TV story)|The End of Time]]'')
** The Doctor cut the link holding Gallifrey out of the Time War, which sent the Time Lords back into the battlefield, the Master joining them. However, he left the Immortality Gate's nuclear bolt running. It went into meltdown and the excess radiation would have dumped into the containment booth with Wilf still inside. Trying to operate the booth in any way would also have the same result. In order to rescue Wilf, the Doctor had to enter the booth and expose himself to the radiation, leading to his regeneration. ([[TV]]: ''[[The End of Time (TV story)|The End of Time]]'')
* On Christmas Eve 2006, an older version of the Tenth Doctor returned to London on the day that his newly regenerated self was battling the Sycorax above the city. On that occasion, he visited a young patient at [[St. Nicholas's Hospital]], [[Daniel Francis Thompson]], and helped him awaken from his coma. ([[PROSE]]: ''[[Deep and Dreamless Sleep (short story)|Deep and Dreamless Sleep]]'')
* The Tenth Doctor mentions [[Arthur Dent]]. Arthur was previously seen alongside [[Zaphod Beeblebrox]] inside the [[Time Lord]] prison [[Shada]] ([[WC]]: ''[[Shada (webcast)|Shada]]'') and would write about the Doctor on the website [[Doctor Who?]]. ([[PROSE]]: ''[[Have You Seen This Man? (short story)|Have You Seen This Man?]]'')

* The Doctor's speech to PM Harriet Jones about how "[[Earth]] is drawing attention to itself" recalls a similar statement made by [[the Brigadier]] in "[[Spearhead from Space]]." Jones's destruction of the Sycorax ship and the Doctor's angry reaction are similar to the conclusion of "[[Doctor Who and the Silurians]]," in which the Brigadier uses explosives to seal off the [[Silurian]] hibernation chambers even as the Doctor departs to begin peace negotiations.

* The Doctor regrows his severed hand, establishing a notable new twist to the mechanics of [[regeneration]] and, in part, suggesting a rationale for [[Romana II]]'s ability to change her appearance several times during regeneration ([[DW]]: ''[[Destiny of the Daleks]]''). The Doctor's severed hand, last seen falling to earth in this episode, is later revealed to have been retrieved by [[Jack Harkness]] (''[[Torchwood]]''); the Doctor would get it back much later ([[DW]]: ''[[Last of the Time Lords]]'') and then, after a botched regeneration, after Donna touched the hand, it would become the [[Meta-Crisis Tenth Doctor]]. When it went to [[Pete's World|the other universe]], it would stay with [[Rose Tyler]]. ([[DW]]: ''[[Journey's End]]'')
* In a scene filmed for the episode, but deleted before broadcast (though included on the DVD), the Doctor attempts to utter his predecessor's catchphrase "Fantastic!" but due to his "new teeth" (ref. his comments at the end of ''The Parting of the Ways'') finds it initially impossible to do so. This scene was intended to set up the final scene of the episode in which the new Doctor finally utters the word "Fantastic!"
*In the scene inside the TARDIS's wardrobe room near the end of the episode, various articles of clothing worn in earlier episodes are visible, including one of [[Steven Taylor]]'s shirts (worn in [[The Celestial Toymaker]]) and the [[Fifth Doctor]]'s panama hat, as well as what appears to be the [[Fourth Doctor]]-like costume that the [[Seventh Doctor]] wore in [[Time and the Rani]].
* The ramifications of the destruction of the Sycorax vessel, including the impact on a group of female (and presumably related) Sycorax, is explored in the comic strip [[DWM]]: ''[[The Widow's Curse]]''.

You may be looking for The Christmas Inversion.

The Christmas Invasion was the 2005 Christmas Special of Doctor Who.

It was the show's first Christmas special since its revival and the first Christmas special starring David Tennant as the Doctor.

It was the first episode of Doctor Who to premiere on Christmas Day since "The Feast of Steven", the seventh part of 1966 twelve-part serial The Daleks' Master Plan. However, unlike that episode, The Christmas Invasion was specially commissioned by BBC One to be transmitted outside the programme's normal broadcasting season. It was thus the first in the modern tradition of the "Christmas special", and its sixty-minute running time made it then the longest episode yet produced by BBC Wales.

Narratively, it continued the story of Harriet Jones, started the Torchwood story arc and involved UNIT in its first major appearance in the new series.

More importantly, it was the first full story to feature the Tenth Doctor, played by David Tennant. Its initial pre-titles sequence on the Powell Estate was later used to "bookend" the closing scenes of The End of Time. Its setting was the first and last place on Earth the Tenth Doctor saw.

To coincide with this release, three short stories were released on the U.N.I.T. website. The first was Alien Life, part of the UNIT Press Briefings mini-series, which was set directly in the aftermath of the Sycorax invasion, where UNIT confirms that aliens exist, and the second and third, Guinevere One and Project Rooftop, part of the Operations Board mini-series, was set during and after The Christmas Invasion, respectively, depicting events of the television story from UNIT's perspective.

Synopsis[[edit] | [edit source]]

It's Christmas Eve and high above London, the alien Sycorax are holding the Earth for ransom. The Tenth Doctor must recover from his regeneration in time to save the human race from slavery.

Plot[[edit] | [edit source]]

It is Christmas Eve on Earth. As Jackie prepares presents and Mickey works in the local garage, both of them hear the distinctive sound of the TARDIS's engines. Rushing out into the street of the Powell Estate, they see the TARDIS blink into existence above them, ricochet off a few buildings and a post van, then come to a crashing halt. A freshly-regenerated Doctor stumbles out of the police box doors, greets the two of them by name and wishes them a merry Christmas before collapsing. Rose follows and, in response to Jackie and Mickey's questions, identifies him as the Doctor.

They bring the Doctor to Jackie's flat and dress him in pyjamas belonging to Howard, Jackie's current beau, who has the habit of keeping pieces of fruit in his pocket for snacks. While Rose discusses the Doctor's change of appearance and the fact he has two hearts with Jackie, they do not see a wisp of regeneration energy emerging from the Doctor's mouth, which then floats off into space. On television, Prime Minister Harriet Jones and project director Daniel Llewellyn give a press conference about the Guinevere One space probe, which is about to land on Mars. In space, however, the probe is swallowed up by an rock-like spaceship.

That evening, Rose and Mickey go Christmas shopping but are attacked by a group of masked Santas armed with lethal musical instruments. Managing to escape when the tuba mortar brings a giant Christmas tree down on the Santas, Rose realises that their attackers are after the Doctor. She and Mickey rush home in a taxi. When they reach the flat, Rose notices an unfamiliar Christmas tree in the sitting room, which Jackie says was delivered to the door. As they deduce that none of them purchased the tree, it suddenly comes to life, whirling around with razor-sharp branches while playing a cheerful rendition of "Jingle Bells" as it tries to slice them all to ribbons. The three retreat to the bedroom with the tree in hot pursuit. As Jackie laments the indignity of being "killed by a Christmas tree", Rose places the sonic screwdriver in the still-comatose Doctor's hand and begs him to help her. Reacting instinctively, the Doctor rises just as the tree bursts through the door and disintegrates it with the screwdriver.

He then strides outside the flat to see who was remotely controlling the tree. From ground level, the Santas stare up at the Doctor, but transmat away when he threateningly points the sonic screwdriver at them. The Doctor calls them "pilot fish" before collapsing in pain: he is still regenerating, and the energy leaking from him has attracted the "pilot fish"'s attention. He tells them he is having a neural implosion because they woke him up too soon, but Jackie keeps interrupting with a stream of increasingly unhelpful suggestions until the Doctor tells her to shut up. He grips Rose, warning her that something bigger is coming, then loses consciousness again.

PM Harriet Jones during the Sycorax crisis.

The first signal from Guinevere One arrives on television: a snarling alien face, which is soon broadcast all over the world. Llewellyn is escorted by Major Blake to the Tower of London, which houses an underground facility run by UNIT. There, he meets the Prime Minister and her aide, Alex, who tells him that they're putting out a temporary cover story that students in masks hacked into the television signal. Llewellyn is shaken to realise that extraterrestrial life does indeed exist and that both the British government and the United Nations are aware of this. A technician, Sally Jacobs, explains that the signal did not come from Mars but 5000 miles above the planet's surface, which means that there is a ship, and it is moving rapidly towards Earth.

As Rose and Mickey use his laptop to access the UNIT website and monitor their readings, the aliens send another signal to Earth. They speak in a language that Rose does not understand; normally, the TARDIS would translate it for her, but it seems that with the Doctor unconscious, that function is not working. Rose examines the bedridden Doctor and finds one of his hearts has stopped, meaning he is too injured to be of use and may die if they attempt to wake him again. Back at UNIT, Blake orders the use of translation software. With no sign of the Doctor, Jones asks Blake about Torchwood. She knows that she is not supposed to know about them – not even the United Nations knows — but she wants them to be ready.

The software translates the message: the aliens are called the Sycorax, and they are claiming the planet as their own, demanding surrender or "they" will die. Their word for "human" also appears to be similar to that of "cattle", temporarily baffling UNIT. Jones declines to surrender, replying to the Sycorax with a warning that the planet is armed. As dawn rises over London, the Sycorax enact their first move. With a wave of the leader's hand, blue energy sweeps over a third of the world's population, mesmerising them. The mind-controlled people, Sally Jacobs amongst them, then climb to the highest spots they can find, primarily the roofs of buildings, and stand at the edge, all of them poised to jump.

Checking the UNIT staff's medical records, Llewellyn discovers that all the affected people have A+ blood. The Sycorax found the sample of A+ blood that was sent with other materials on Guinevere One to identify the human race in case of alien contact, and are somehow using that as a control mechanism. Desperate now, Jones gives an emergency broadcast on television, informing the public that the Queen's Christmas speech has been cancelled as the Royal Family are "on the roof", and pleads for the Doctor's help if he is out there. Driven to despair by the Doctor's comatose state, Rose breaks down in tears in Jackie's arms.

Harriet Jones aboard the Sycorax's ship

Just then, the shockwave of the Sycorax ship entering the atmosphere shatters windows all over the city; the gigantic craft takes position above the Houses of Parliament and an under-reconstruction Big Ben as the frightened population watch. Rose, not knowing what else to do, asks Mickey and Jackie to help her move the Doctor to the safety of the TARDIS. Jackie gathers food and other supplies, including a thermos flask of tea.

The Sycorax teleport Jones, Alex, Blake and Llewellyn up to their ship, where the Sycorax leader removes his helmet, revealing a skinless face surrounded by a mantle of bone. His hand hovering over a large glowing button, he demands immediate surrender, or he will order the mind-controlled humans to jump. Llewellyn tries to reason with the Sycorax but is reduced to a pile of bones by the leader's energy whip, as is Blake when he protests. The choice is left to Jones; half of the world will be sold into slavery or a third will die.

As Rose and Mickey move the Doctor into the TARDIS console room, Jackie goes back to get more supplies. Rose, having apparently given up, broods by the console as Mickey tries to use the scanner to tune into what is happening, but the time machine's advanced technology is detected by the Sycorax. Outside, Jackie watches helplessly as the TARDIS is transmatted up. Not realising that they are aboard the Sycorax ship, Rose steps out of the TARDIS and screams when she sees the aliens. Mickey rushes out after her, dropping the flask of tea, which spills and starts dripping through the grilles at the base of the console next to the Doctor's unconscious form. The Doctor breathes in the subsequent fumes as the tea sparks against various components.

Reunited with Harriet Jones, Rose tries to bluff the Sycorax by citing various things and races she has encountered on her travels, commanding them to leave, but is answered with laughter. The Sycorax leader taunts her attempts to pass off second-hand knowledge as authority... but as he gloats, his alien words start being replaced with English. Rose realises that the TARDIS translation ability is working again, and since the Doctor must be conscious for it to be active, that can mean only one thing: the Doctor is awake. On cue, the Doctor emerges from the TARDIS in Howard's dressing gown, smiling as he says, "Did you miss me?"

Easily deactivating the Sycorax leader's energy whip and breaking his staff, the Doctor bluntly tells the alien to wait while he gets more important things out of the way; namely, getting reacquainted with his friends. Disappointed at not being "ginger" (red-haired), and somewhat annoyed at Rose's speed in giving up on him, he tells them that all he needed was a "good cup of tea; a superheated infusion of free radicals and tannin. Just the thing for healing the synapses." As the Sycorax leader demands to know who he is, the Doctor blithely strides across the ship's floor, nattering on cheerfully and still working out what his personality is like in this new incarnation. He walks up to the glowing button, discovers that it is powered by A-positive human blood, and quickly deduces that the Sycorax are using blood control — they're controlling all the humans with A-positive blood. The Doctor tells the leader that in his unstable state, when he sees a large glowing button he just cannot help himself — and to everyone's shock, he pushes it.

However, instead of sending the possessed crowds on Earth to their deaths, it simply releases them from the Sycorax control. The Doctor explains that blood control is like hypnosis: "you can hypnotise someone to cluck like a chicken or sing like Elvis, but you can't hypnotise them to death. Survival instinct's too strong." The Sycorax were bluffing, and the Doctor called them on it. The leader says that they can still conquer Earth by force with an armada, but the Doctor demands that the humans be left alone (quoting part of "The Circle of Life" from The Lion King in the process), challenging the leader to single combat for the planet.

The Doctor goads the leader into the fight by insulting him in his native Sycoraxic. The swordfight ranges from inside the ship to its exterior; in the midst of it, the leader cuts the Doctor's hand off, and it falls to the city below along with his sword. The leader assumes the Doctor will yield as he's been "disarmed". But while his friends are horrified, the Doctor is calm; he notes that he is still within the first fifteen hours of his regeneration cycle. Grinning, he explains that there's enough leftover energy after the change to rectify any anomalies or missing bits; and his hand regrows.

Grabbing a new sword, the Doctor notes "This new hand, it's a fightin' hand!" and reengages the leader in battle, ultimately winning the duel. The Doctor pins the leader to the edge of the ship with his sword, commanding him to leave the planet and never return in exchange for sparing his life. As the Sycorax leader appears to yield and the Doctor walks back to celebrate his victory with Rose, he attempts a final attack whilst the Doctor's back is turned. In response, the Doctor calmly bounces a satsuma he finds in Howard's dressing gown off a control button, opening a section of the ship's wing beneath the leader, sending the alien plunging to his death. With a now-grim expression, the Doctor declares he is a man who doesn't give second chances.

The Doctor sends the other Sycorax on their way with a reminder that the planet Earth is defended, and he and his human friends are transmatted back to London to reunite with Jackie. Jones asks the Doctor if there are more aliens out there, and he confirms that there are thousands; the human race is being noticed more and more and it is something they will have to get used to. As Jones ponders this, visibly troubled, Alex receives a telephone call and quietly informs Jones that Torchwood is ready. Jones appears reluctant, but nevertheless gives the order to fire. The Doctor and his friends watch in shock as five green beams converge into one over London, and the resulting energy burst destroys the Sycorax ship as it heads into space.

The Tenth Doctor asks Alex, "Don't you think she looks tired?"

The Doctor is furious with Jones, but the Prime Minister tries to justify the use of the weapon (engineered from a crashed spaceship ten years previously) as defending the planet. She tells him how Llewellyn and Blake were mercilessly killed in front of her while the Doctor was asleep, making her realise he cannot be there all the time. The Doctor bitterly retorts he should have warned the Sycorax to run, as the real monsters, the humans, are coming. When Jones asks if she should consider the Doctor another alien enemy, the Doctor warns her that he can bring down her government with just six words, which he whispers into Alex's ear: "Don't you think she looks tired?" Alex gives Jones a startled look, and she demands to know what the Doctor just said, growing frantic in her attempts. Everyone else leaves without a word, and Jones can only apologise quietly.

While the Doctor looks through the TARDIS wardrobe for a new outfit to suit his new incarnation, Jackie, Mickey and Rose serve Christmas dinner in the flat. The Doctor joins them to celebrate, having finally settling on a brown pinstripe suit and a long brown coat. On television, Harriet Jones is seen fending off rumours about her ill-health and a pending vote of no confidence in the House of Commons. Outside, what looks like snow is falling over London, accompanied by shooting stars, but the Doctor points out that it is, in fact, ash — the remains of the Sycorax spaceship breaking up in the atmosphere. It is a new start for Earth, however; with so many people seeing the Sycorax ship, there is no covering up the existence of aliens this time.

But there are new worlds to see and explore. With a now-trusting Rose by his side and eager to continue their travels, the Doctor looks up into the sky to choose a star for their next destination, assuring her that it will be, in the words of his previous incarnation, "fantastic".

Not every person who worked on this adventure was credited. The absence of a credit for a position doesn't necessarily mean the job wasn't required. The information above is based solely on observations of the actual end credits of the episodes as broadcast, and does not relay information from IMDB or other sources.
          

With The Christmas Invasion came an explosion in the number of people regularly credited on Doctor Who. In particular, the art department got much more specific crediting than had ever been the case in series 1. This trend of expanding the number of art department personnel credited would continue right through to series 5, with each series regularly crediting a few more positions.

Technology[[edit] | [edit source]]

  • The Hubble Array is following the course of the Sycorax ship.

Notes[[edit] | [edit source]]

  • This is the first Doctor Who episode clearly labelled as a Christmas special. The seventh episode of The Daleks' Master Plan, titled "The Feast of Steven", was written as a Christmas episode and was first broadcast on 25 December 1965.
  • This is the first episode of the 2005 revival of Doctor Who to air on a Sunday in the UK.
  • David Tennant is credited as "The Doctor", as opposed to Christopher Eccleston who was credited as "Doctor Who". The change in the credit was done at Tennant's request.
    • This occurrence parallels Peter Davison's request for an identical change in credit when he succeeded Tom Baker. Like Tennant, Davison's first episode would begin this new billing.
    • This story was effectively the first since 1989's Survival to credit the role as "The Doctor".
  • The "middle eight" section of the theme tune is restored in this episode and is heard for the first time in the revived series.
  • Before this episode was broadcast, a tie-in website for the Guinevere One project was created and launched by the BBC. The site includes an introduction by Harriet Jones and an interview with the project director, Professor Daniel Llewellyn. The site claims that the probe was developed by the British Rocket Group. The organisation's logo partially appears in this episode, in the televised press conference with Professor Llewellyn. The name of the organisation was first mentioned in Remembrance of the Daleks and is a reference to the British Experimental Rocket Group from the Quatermass science fiction serials of the 1950s. David Tennant had previously starred in the 2005 BBC live remake of The Quatermass Experiment as Doctor Gordon Briscoe, and Quatermass' first line to Briscoe was changed by actor Jason Flemyng during the broadcast from "Good to have you back, Gordon" to "Good to have you back, Doctor" — Tennant's casting as the Doctor was announced two weeks after Quatermass went to air, and his castmates would have been aware of the speculation during rehearsals.
  • Immediately following this episode, Attack of the Graske, an interactive mini-episode starring David Tennant, was made available on the BBC Red Button.
  • Just before the opening credits sequence, Jackie says the line, "Doctor? Doctor who?", continuing a long-running in-joke. Unlike many instances of the joke, however, the line primarily plays as a genuine question, since she has never before met the Tenth Doctor and knows nothing of regeneration.
  • The Tenth Doctor speaks with an accent similar to Rose's but unlike the Ninth Doctor's Northern one. In a radio interview broadcast on 23 December 2005, David Tennant explained that a line of dialogue had been scripted for this episode which explained that the newly regenerated Doctor had imprinted on Rose's accent, "like a chick hatching from an egg", but the line was deleted from the final episode. This concept would later be added back into the novelisation.
  • The opening shot of this episode, in which the Earth and its moon appear, is reused footage from the opening shot of the episode Rose.
  • The song being played by the Santa Claus band which attacks Rose and Mickey is "God Rest Ye Merry, Gentlemen". This song is traditionally associated with the novel A Christmas Carol, written by Charles Dickens, whom the Doctor and Rose met in The Unquiet Dead. The song shares its melody with the "Venusian Lullaby" the Third Doctor sang in The Dæmons and The Curse of Peladon. The carol can be heard again in The Next Doctor.
  • Another song featured in this episode is "Song for Ten", an original composition by Murray Gold sung by Tim Phillips. The next two Christmas specials included an original song on the soundtrack. The Phillips version of the song was very brief, and when the time came to compile a soundtrack album, new lyrics were written for the song (reflecting the events of Doomsday) and it was recorded by Neil Hannon. "Song for Ten" is the first original song commissioned for Doctor Who since the untitled rap song for the Ringmaster heard during the 1988 story The Greatest Show in the Galaxy.
  • One of the outfits considered by the Doctor in the wardrobe is the costume worn by David Tennant in his previous role as Casanova in the eponymous television serial.
  • This marks the first time in the new series that any room in the TARDIS other than the console room is seen on-screen.
    • It is also the only appearance in the first Russell T Davies era of an area of the TARDIS outside of the console room.
  • In a scene filmed for the episode, but deleted before broadcast (though included on the DVD), the Doctor attempts to utter his predecessor's catchphrase, "Fantastic!" but due to his "new teeth" (ref. his comments at the end of The Parting of the Ways) finds it initially impossible to do so. This scene was intended to set up the final scene of the episode in which the new Doctor finally utters the word, "Fantastic!"
  • The Christmas Invasion can be viewed in its entirety on the BBC America website.
  • A signal intrusion incident that occurred in Chicago during an airing of the Fourth Doctor serial Horror of Fang Rock is referenced by Harriet Jones' aide Alex when he says the official story of the Sycorax appearing via the probe is because of "a mask, some sort of prosthetic. Students hijacking the signal."
  • This was the first time a television drama was permitted to film atop the Tower of London.[2]
  • This is the first episode to use music performed by the BBC National Orchestra Of Wales, in contrast to all previous episodes of the revived series which used a computer-created soundtrack.
  • Harriet Jones states that the laser that destroyed the Sycorax was taken from technology of a ship that crashed a decade ago, placing the time of the crash in 1996.
  • Russell T Davies wrote the script with the Ninth Doctor in mind, the idea being that the characteristics of the Tenth Doctor would emerge more through David Tennant's portrayal than from scripted lines.
  • At one stage, the Sycorax were assisted by an ill-fated civil servant called Sir Aubrey. Having destroyed Big Ben in Aliens of London, Russell T Davies considered a scene in which the Sycorax spaceship decimated the newly-rebuilt structure, leading to Sir Aubrey's death beneath the falling rubble. Instead, he decided to demolish a much more modern London landmark: the Gherkin.
  • The TARDIS wardrobe contains a Hogwarts uniform. David Tennant was fresh off his appearance as Barty Crouch Jr. in Harry Potter and the Goblet of Fire.
  • The prototype of the Sycorax swords was auctioned on eBay to raise funds for the Great Ormond Street Hospital Children's Charity. It raised £920.51.
  • Phil Collinson was fond of Harriet Jones, and he argued against her downbeat fate, which was partly fuelled by the sense of betrayal Russell T Davies felt towards Tony Blair.
  • The Guinevere 1 probe was inspired by the Beagle 2, a British-made spacecraft which landed on the surface of Mars on Christmas Day 2003. Sadly, the malfunction of its solar panels prevented the Beagle 2 from establishing contact with its operators on Earth, and the mission was deemed a failure. Davies also remembered the first pictures sent from Mars by the Viking 1 lander in July 1976, and he wanted the Guinevere 1 to transmit something more exciting than the empty, bleak Martian landscape.
  • Because the United Nations had reacted unfavourably to a UNIT website set up by the BBC to help promote Season One, Russell T Davies decided to refer to UNIT by the acronym only.
  • Two of the blood-controlled children were named after Russell T Davies' nephew and niece, Jonathan and Catrin.
  • Some consideration was given to moving to high-definition recording, but it was ultimately decided to retain the Digital Betacam format used during Series 1.
  • During the four months which had elapsed since filming wrapped on Bad Wolf/The Parting of the Ways, Billie Piper had adopted a noticeably shorter hairstyle, not realising that the events of the special would occur in its immediate aftermath. As a result, it was decided that she would wear hair extensions for the holiday special.
  • Freema Agyeman auditioned for the role of Sally Jacobs, but the production team felt that she was deserving of a more prominent role. She would later play Adeola Oshodi in Army of Ghosts before landing the role of Martha Jones.
  • Peter Davison visited filming at the Brandon Estate.
  • Torrential rain prevented some of the Powell Estate sequences from being completed in London. They were instead taped at Loudoun Square in Cardiff.
  • For the interior of the Sycorax ship, Russell T Davies wanted to avoid a traditional metallic spacecraft. As such, these scenes were recorded at Clearwell Caves in Gloucestershire.
  • Russell T Davies hoped to reprise a shot originally intended for Rose, tracking from outside the TARDIS, through the doors and into the console room to reveal the revived Doctor. Unfortunately, these plans had to be abandoned due to the difficulty of transporting the motion-capture equipment into the caves.
  • The overall pace of the Gloucestershire work was very slow, hampered by both the technological limitations imposed by the environment and Sean Gilder's difficulties with the contact lenses he wore as the Sycorax Leader. This forced an additional day at Clearwell Caves.
  • It was originally thought that the swordfight between the Doctor and the Sycorax Leader on the wing of the spaceship would be performed on the roof of a tall building in Cardiff. However, James Hawes could not find a venue which obscured the surrounding conurbation, and so the sequence was instead filmed against an unobstructed view of the sea at the docks in Barry.
  • Originally, Russell T Davies had hoped to emphasise the global threat of the Sycorax by including scenes of blood-controlled humans near the pyramids and on Sydney Harbour Bridge. However, neither shot could be realised convincingly, and they were both dropped.
  • A deleted scene saw the Tenth Doctor realising that his predecessor's “Fantastic!” catchphrase no longer suited him.
  • The concluding scene initially saw the Doctor and Rose ruminating on how they missed the Ninth Doctor, but the production team felt that the special should be looking to the future in its closing minutes, rather than reflecting on the past.
  • To accompany the scene of the Doctor in the TARDIS wardrobe, Russell T Davies originally wanted to use the 1963 version of "The Bells of St Mary's" by Bob B Soxx & the Blue Jeans. When the rights proved prohibitively expensive, Murray Gold was instead asked to create an original tune. The result was "Song for Ten".

Ratings[[edit] | [edit source]]

  • 9.84 million[3]

Myths[[edit] | [edit source]]

  • Some early reports suggested that the enemy would be the Cybermen. Tabloid newspaper The Sun reported that Shaun Dingwall would return as Rose's father, Pete Tyler, and that this episode would be set on an alternative Earth. However, all of these claims were proven to be incorrect when the episode was broadcast, and appear to refer to Rise of the Cybermen/The Age of Steel. Coincidentally, the Cybermen were later announced as the enemies in the later 2008 Christmas special.
  • After the announcement that Christopher Eccleston would leave after the first series, there were erroneous reports that the regeneration was to take place during the Christmas special, not during The Parting of the Ways. (This may have been an intentional red herring in order to maintain at least some element of surprise for the series finale given that the BBC had accidentally blown Russell T Davies' plan for a surprise regeneration.)

Production errors[[edit] | [edit source]]

If you'd like to talk about narrative problems with this story — like plot holes and things that seem to contradict other stories — please go to this episode's discontinuity discussion.
  • When Mickey calls Rose to check out the military broadcast of the Sycorax ship, you can see for a split-second the video player playing the broadcast, revealing that it was not green-screened, but a video playing on the computer.
  • Although it has been a very short time since the Doctor regenerated, as Rose passes the door of the TARDIS after the Doctor collapses, her hair is visibly longer. (TV: The Parting of the Ways) This exposes the several month break between the wrapping up of Series 1 in March 2005, and the beginning of filming for Series 2 in July, during which time Billie Piper allowed her hair to grow longer.
  • When proclaiming his new form to be "lucky", the Doctor is facing towards the Sycorax ship, but when mentioning being in the first 15 hours of his regenerative cycle, he is facing away from the Sycorax ship. He is facing the ship again when his hand regrows.
  • A lot of the shots between the Doctor winning the challenge and giving his warning to the Sycorax horde have inconsistent lighting. One notable example of this is when the Doctor throws the satsuma, the light is on the right side of his face but is then on the left side of the button the fruit hits when it should be on the right. The green screen of the ship exterior is also darkened on the left side, making this error more prominent.
  • In one of the Tower of London scenes, the Guinevere 1 Space Probe is incorrectly spelt "Guinivere 1" on a computer screen.
  • In the 2017 Series 2 Blu-ray Steelbook, Phil Collinson, the producer of this episode, is incorrectly credited after the title sequence as "Phil Collision".

Post-regeneration stories
For the purposes of this list, a "post-regeneration story" is one in which the after-effects of a regeneration is actually and initially depicted and the Time Lord fully settles into their new body. For this reason, Rose is not included below, even though it is commonly thought of as a "post-regeneration story". It doesn't actually include a clear scene of regeneration, and the preponderance of stories in other media confirm that the Ninth Doctor has not immediately regenerated prior to the story.

Regeneration is usually considered a biologic process exclusive to Time Lords and a few other species. However, some consider Regeneration to also be a "post-regeneration story", though neither describes anything close to a biological process.

Sycorax stories
For the purposes of this list, a "Sycorax story" is one in which one living, authentic Sycorax plays a part within the confines of the story, outside of flashbacks to previous stories and cliffhangers that lead into the following story. Stories like The Pandorica Opens and Revolution of the Daleks are also not included due to the Sycoraxs' cameos being of no consequence to the plot of the story.
