The Poison Sky was the fifth episode of the fourth series of Doctor Who.
Synopsis
As the Sontarans choke the Earth, the Doctor battles to keep both Martha and Donna alive while trying to figure out the composition of the gas ATMOS cars are producing for the warriors of Sontar.
Plot
Sylvia manages to free Wilf from the car by smashing the window. The Tenth Doctor sends Donna Noble back to the TARDIS while he sets off to figure out what the Sontarans are up to. After studying the gas, UNIT determines that it will need to reach 80% density to become poisonous. Elsewhere, Clone Martha has the hypnotized UNIT soldiers Harris and Gray transport the TARDIS to the Sontaran flagship. Realising that he is trapped, the Doctor attempts to goad the Sontarans into revealing their plan: the Sontarans are smart enough not to fall prey to this ploy, but the Doctor does trick them into manoeuvring the TARDIS out of the main war room, placing Donna in a position to help.
Against the Doctor's advice, UNIT decides to use nuclear weapons against the Sontarans; however, Martha's clone has covertly copied the launch codes, and stops every attempt they make to fire the weapons. This in itself shows a hidden agenda: nukes would not have harmed them in the first place, which combined with the unidentifiable elements in the gas, suggest that the Sontarans have an interest in keeping anything from disrupting the atmospheric conversion. At the same time, the Sontarans mobilize a contingent of troops to retrieve and protect the clone. With the Sontarans' ability to jam most conventional firearms by expanding the copper-lined bullets, the UNIT troops are quickly slaughtered and the factory is secured.
Rattigan leaves the Sontaran mothership to gather his students. He plans to take them to another planet and begin the human race anew. The students merely laugh him off, even when he brandishes a gun. When he returns to report his failure, the Sontarans likewise ridicule his efforts, having never planned to take him or his students anywhere. Rattigan teleports back to his mansion before they can kill him, and the Sontarans lock the teleport pods behind him.
Meanwhile, the Doctor instructs Donna on how to reopen the teleport pods. While Donna makes her way through the ship, UNIT, using the Valiant's Turbofan engines to clear an area around the factory, a Sunglider weapon - smaller than that used against the Sycorax - as their main offence and steel-encased bullets in lieu of copper, begin a retaliatory strike. The counterattack is a success, and the UNIT troops are able to put the Sontarans on the defencive.
The distraction allows the Doctor to make his way to the cloning room where Martha is being held. Having figured out long before that the clone wasn't the genuine article (but keeping her to stop the nuclear weapons), he severs its connection to Martha, leaving it to die. Martha convinces the clone to betray the Sontarans in its last moments, and the clone reveals that the poison gas is actually "clone feed" for Sontaran clones: they are converting the planet into a giant breeding world. With Donna's help, the Doctor is able to reactivate the teleport pods, allowing him to rescue Donna, steal back the TARDIS, and teleport into Rattigan's mansion.
With the equipment Rattigan's students built, the Doctor builds his own atmospheric converter, igniting the atmosphere to clear out the poison gas. However, he knows the Sontarans won't accept defeat so easily - they are beginning their standard invasion stratagem, so he tells Donna and Martha to lead good lives, tells Rattigan to go on and do something incredible, and teleports to their ship with the converter, planning to give them the choice between retreat or death. The Sontarans choose the latter, but the Doctor cannot bring himself to destroy a ship full of sentients. However, with a few seconds left, Rattigan teleports himself to the Sontaran ship and simultaneously teleports the Doctor back to Earth and, with the Sontarans stopping their "haka" with the new development, he simply says "Sontar? Ha!" and detonates the device..
With the day saved, the Doctor and Donna say their goodbyes to Martha, only to have the TARDIS spring to life and begin piloting itself to places unknown before she can leave, the Doctor's hand jar bubbling...
Cast
- The Tenth Doctor - David Tennant
- Donna Noble - Catherine Tate
- Martha Jones - Freema Agyeman
- Rose Tyler - Billie Piper
- Wilfred Mott - Bernard Cribbins
- Sylvia Noble - Jacqueline King
- General Staal - Christopher Ryan
- Commander Skorr - Dan Starkey
- Colonel Mace - Rupert Holliday Evans
- Luke Rattigan - Ryan Sampson
- Ross Jenkins - Christian Cooke
- Captain Price - Biddy Hodson (credited as "Bridget Hodgson")
- Private Harris - Clive Standen
- Private Gray - Wesley Theobald
- Newsreader - Kirsty Wark
- Trinity Wells - Lachele Carl
Production crew
- Uncredited: Alice Troughton (director, Billie Piper sequence, used again in DW: Midnight)
References
- The Doctor mentions the Rutans and the Rutan-Sontaran War.
- The Brigadier is said to be stranded in Peru. He has obviously been knighted as Colonel Mace refers to him as "Sir Alistair". This is the first reference to the character in Doctor Who since the 1989 story Battlefield, although several references occurred in the first season of The Sarah Jane Adventures, broadcast in 2007. The Brigadier was knighted in the book NA: The Dying Days and called "Sir Alastair" in Big Finish Productions' audio dramas.
- The Doctor asks "Are you my mummy?" while wearing a gas mask like the Empty Child from (DW: The Empty Child)
- The Doctor addresses the Sontarans "under Jurisdiction Two of the Intergalactic rules of engagement" which is very similar to the Shadow Proclamation.
- The Doctor watches Tommy Zoom while waiting for the Sontarans to stop chanting. This is similar to when The Master watches other shows such as Teletubbies and The Clangers.
- UNIT uses the Valiant to blow away ATMOS' gases. When the Doctor admires the ship and Colonel Mace asks if he has a taste for it, the Doctor is quick to reply "Not at all. Not me." This can be interpreted as masked reluctance from the Doctor to acknowledge any similarities between himself and The Master, who was very keen on the Valiant. Most likely, though, it was simply the Doctor reacting to the unpleasant memories of his year spent in captivity aboard the vessel.
- The Valiant's laser is similar to that of Torchwood 1 one used against the Sycorax, which in turn was very similar to the Death Star's laser from the Star Wars movies. (DW:The Christmas Invasion)
- During the pollution crisis the American newsreader mentions that it is the "end of days" which was also said after Owen opens the rift and caused shockwaves around the world. (TW:End of Days)
- The Doctor mentions Jack Harkness when he confronts the Martha clone.
- Luke Rattigan believed the Sontarans would take him and his followers to Castor 36, a planet orbiting Alpha Geminorum.
- The close-up of the news reader's eyes and mouth are reminiscent of the Doctor's message during Blink.
Story notes
- Helen Raynor wrote this episode. Her Series 3 episodes Daleks in Manhattan and Evolution of the Daleks both occupied fourth and fifth episode in the series. This two part episode also occupies episode four and five.
- This the second part of a story which began with The Sontaran Stratagem.
- This story and The Sontaran Stratagem are Douglas Mackinnon's first stories as director.
- When the Doctor cuts off Staal's speech on the video screen in mid flow, a clip from CBeebies cartoon Tommy Zoom is featured. The original plan to use a clip from Shaun the Sheep fell through.
- Billie Piper appears very briefly as Rose Tyler on the TARDIS's screen in this episode. She receives screen credit, and is fourth-billed, for a performance that lasts less than one second and which was actually shot for another episode.
- According to Russell T Davies in an interview in DWM 396, the cameo by Rose was not in the original edit of the episode, but was added just before broadcast when Davies learned how successful her unbilled cameo in Partners in Crime was. Although it was reported that the clip came from "an untransmitted scene" from another episode, in fact, according to the DVD commentary for Midnight, the scene was shot especially for Midnight during production of Turn Left and Davies dropped the scene into The Poison Sky, too. Davies said that, like Partners in Crime, advance review copies of this episode did not include the cameo. This scene was directed by Alice Troughton.
- The music that plays when the Valiant appears is strikingly similar to "The Master Tape", one of the Murray Gold themes for The Master. Of course, since The Master helped build the Valiant, this isn't too surprising...
- When Martha Jones wears the Doctor's jacket at the end of the episode, she says she feels like "a kid in my Dad's clothes." The following episode features an actual daughter of the Doctor.
- This is the first episode to feature Billie Piper, Freema Agyeman, and Catherine Tate all together as Rose, Martha, and Donna, respectively.
- The Doctor says to the clone Martha: "Avanti" which is "Let's go" in Italian. This is probably to confirm his suspicion of her clone nature. The real Martha would know that the Doctor usually says "Allons-y" which is "Let's go" in French.
Ratings
- 6.5 million viewers
Myths and Rumours
- Billie Piper's brief cameo was taken from an earlier episode, most likely The Idiot's Lantern in which she was also shown shouting silently from a TV screen. In fact, the scene was filmed especially for Midnight, and inserted into this episode at the last minute.
Filming locations
Studio
- Upper Boat Studios, Trefforest
- BBC Broadcasting House, Llandaff
Location
- Margam Country Park, Port Talbot
- Usk Valley Business Park, Pontypool
- Nant Fawr Road, Cardiff
- Orion Electric, Port Talbort
- Roath Basin, Cardiff Docks
Production errors
- When Martha's clone enters the mobile HQ, it can be seen that she entered through a normal building's door (with daylight coming in through the window) which isn't present on the back of the vehicle or in the previous episode.
- During the end we see the Sontaran's weapons starting to target the Earth, they get ready and open up, yet, when it's destroyed, they're still closed.
- During the warehouse battle, around when the Doctor tells Donna, "Hold on, I'm coming", the film crew can be seen reflected in a door at the right of screen.
- When Colonel Mace confronts Commander Skorr, he raises his gun twice; Once in one shot, and immediately after in the other.
Continuity
- The Valiant last appeared in DW: Last of the Time Lords.
- At the end of the episode, when the TARDIS flies off, the Doctor says his "What?! What?! What?!" line from Donna's first appearance in DW: The Runaway Bride and also from The Voyage of the Damned when the Titanic smashed through the TARDIS.
- Rose Tyler appears on the TARDIS scanner screen for a split second, she appears to be shouting 'Doctor!' and was last seen in DW: Partners in Crime. This is not the first time Rose has attempted to communicate with the Doctor though a television screen, as she also attempted this in DW: The Idiot's Lantern.
- After the Sontarans fill the area with gas the Doctor wears a gas mask. While being shown a gun by Colonel Mace, he is asked what he thinks. His reply is "Are you my mummy?", a reference to the episodes The Empty Child and The Doctor Dances, in which the child asks this question numerous times. It is worth noting that these episodes did not feature David Tennant as the Doctor, but instead Christopher Eccleston as the Ninth Doctor.
- The Valiant's laser appears to be the same that Torchwood used in DW: The Christmas Invasion (Similar, not the same - this one's much smaller)
- The Doctor thanks Donna and Martha just before he tries to sacrifice his life. He last said this to Donna in DW: The Sontaran Stratagem when she was supposedly leaving him.
- In the New York scene a building with the name "Butler Institute" can be seen on one of the buildings, the Butler Institute first appeared in NA: Cat's Cradle: Warhead.
- Gas was released over London previously in PDA: Amorality Tale.
- The Doctor gave clues to Donna about what action to take via a visual link, but the Sontarans didn't know it was happening. The Doctor did a similar thing in DW: The Age of Steel, when he gave clues to Mickey about how to stop the Cybus Cybermen.
- In DW: Turn Left, the Sontaran invasion was stopped by Torchwood 3. The atmosphere was reverted to its previous state and the Sontaran flagship exploded by Gwen Cooper and Ianto Jones. Jack Harkness was stranded on the Sontaran's home planet.
- The destruction of the Sontaran ship will be shown again in SJA: The Last Sontaran.
- When The Doctor yells at Colonel Mace, David Tennant's gold tooth can be visibly seen. This became the subject of an internet meme wondering if The Doctor regenerated them or if he has practised lacklustre dental hygiene in his Tenth incarnation's relatively short life and, that being the case, chastising him.
Timeline
- This story takes place after DW: The Sontaran Stratagem
- This story takes place before DW: The Doctor's Daughter
Home video releases
- Released in the Series 4 DVD boxset in November 2008 along with the rest of the Series.
