Twice Upon a Time (TV story)
Twice Upon a Time was the 2017 Christmas Special of Doctor Who.
It was the final chronological appearance of Peter Capaldi as the Twelfth Doctor and introduced Jodie Whittaker as the Thirteenth Doctor in its closing moments.
It was the show's thirteenth Christmas special since its revival and the fourth starring Capaldi as the Doctor. In numeric irony, this Christmas special introduced the Thirteenth Doctor.
The episode reiterated the Doctor's belief that most things in the universe will be hostile, first revealed back in The Pilot. However, it also shows, when he is wrong about the encountered's intentions, the Doctor is clueless about what to do. It also showed the Doctor almost always expects to immediately go into a confrontation with an unknown, possibly hostile, force; he was quite surprised that his warning of Earth being protected to scare off the Testimony worked for once.
After a surprise appearance at the end of TV: The Doctor Falls, the First Doctor was an integral part of this narrative. Here, he was portrayed by David Bradley, who had previously played the original actor William Hartnell in An Adventure in Space and Time. Though so-called "classic" Doctors had appeared on 21st century Doctor Who before, this episode was the first televised interaction between a Shepherd's Bush- and a BBC Wales-era Doctor since 2007's Time Crash. Archival footage from The Tenth Planet was used to bookmark the First Doctor's place in this story. The special also introduced Archibald Hamish Lethbridge-Stewart, credited as "the Captain", a new member of the Lethbridge-Stewart family.
Ben Jackson and Polly Wright made a brief re-reappearance in the programme for the first time since their exit in 1967's The Faceless Ones. Bill Potts joined the two Doctors, and Captain Lethbridge-Stewart, as a Testimony glass avatar. Past companions Nardole and Clara, made similar brief appearances. The "good Dalek" Rusty, from Capaldi's second episode, Into the Dalek, made his second appearance—in Villengard, a location mentioned only once before on television, in Steven Moffat's second television story, 2005's The Doctor Dances.
In early 2018, Murray Gold announced his departure from Doctor Who after twelve years at the Gallifrey One convention, confirming that Twice Upon A Time was his last episode. To replace Murray Gold as main composer of the series, Segun Akinola was hired the following year. It was also the final story with Steven Moffat as head writer and the first to include any part written[1] and overseen by — if not credited to — incoming lead writer Chris Chibnall.
While not known at the time, this would also turn out to be the last consecutive Christmas special of the revived series, breaking the streak that began with The Christmas Invasion.
Synopsis
As the Doctor nears regeneration, he stumbles on his original self, also refusing to change. It takes a captain, a glass avatar and a familiar face to convince the Doctors the universe still needs them.
Plot
The First Doctor nears his death after an encounter with the Cybermen from Mondas. He is freed from his restraints by his companions Ben and Polly, now that the threat is over. However, he is weak, his body beginning to regenerate. Refusing to give in, the Doctor leaves and wanders the South Pole, mumbling to himself that he will not change. Nearing his TARDIS, he hears a voice in the distance yelling in defiance. Seeing a figure kneeling outside his TARDIS, the Doctor asks who the man is. The man claims to be the Doctor. With a smug sense of superiority, the First Doctor tells the man that's not true; "you may be a doctor, but I am the the doctor. The original you might say."
The scene transitions to the Twelfth Doctor as he gets to his feet, shocked to see his past self. The Doctor is delighted at meeting his first incarnation but realises that he is refusing to regenerate; he panics as he doesn't remember refusing to to regenerate the first time or meeting himself. The First Doctor is confused and dismisses his future self as just another Time Lord; he asks if he has come to take back "the ship". The Twelfth Doctor laughs in amusement that his original incarnation still calls the TARDIS "the ship".
The First Doctor then asks what the Twelfth has done to the TARDIS, as its bigger than it used to be. The Twelfth Doctor tells him its from "all those years of being bigger on the inside. You try keeping your tummy tucked in that long", defending his beloved vessel. The Twelfth Doctor questions why his younger self is refusing to regenerate, fearing the consequences the decision might cause. However, the snow suddenly freezes in midair, capturing the pair's attention, as a man dressed in World War I attire approaches them. He seems disorientated and asks the pair if either of them are a doctor. Exchanging a glance with the First Doctor, the Twelfth asks if the man is making some sort of joke.
On Christmas Day 1914, the soldier, a captain in the British Expeditionary Force, lies in a shell hole on the battlefield in Ypres. His revolver is aimed at a German soldier, who also has his sidearm trained on the Captain. Both men realise they will kill each other in self-defence, their respective troops far away in their trenches, unable to assist either of them. Just as the Captain prepares to accept his fate and fire, a wave of energy flows through the field, freezing everything around him. As he exits the hole, a bright light suddenly flashes and encapsulates him. He collapses to the ground in the Arctic and hearing the two Doctors discussing the static snow, he approaches them.
The scene once more shifts back to the Twelfth Doctor's perspective. A portal of light opens in the distance, and the two Doctors approach it. The First Doctor orders the portal to reveal itself, while the Twelfth Doctor declares that the planet is protected, to the confusion of his first incarnation. However, the light quickly vanishes, surprising the Twelfth Doctor as "that almost never works." The First Doctor returns to the Captain, telling him to enter his TARDIS, and the Twelfth Doctor coaxes him to follow. As they enter, the First Doctor is shocked by the changes to the TARDIS interior, while the Captain is shocked by the room's size. The Twelfth Doctor pulls the monitor over to the First Doctor, telling him his TARDIS is 70 feet away; he then tells him to always remember where he parks as it gets important later.
The First Doctor demands his identity, to which the Twelfth says not to be an idiot as they always know when they meet each other. However, the First Doctor states he does not know, prompting the Twelfth Doctor to show him his hand glowing with regeneration energy. The First Doctor wonders if the Twelfth is his next incarnation, to which the Twelfth says is not the case; he'll become him eventually. The First Doctor mutters that he thought he would get younger when he regenerated, to which the Twelfth snaps that he is younger than the First Doctor. The Captain interrupts, stating he does not understand what's happening, while examining a VHS tape. The Twelfth Doctor says that's understandable for a solider from World War I being chased through frozen time by an unknown force. Disturbed upon hearing the Great War being called the first world war, the Captain asks the Doctor what he's talking about; the Doctor simply tells him "spoilers".
The First Doctor notices the Captain's unease, telling the soldier to sit down and orders the Twelfth Doctor to fetch some brandy. He does so, and the First Doctor notices that there is less in the glass than he remembered. The Twelfth Doctor tells him that it's been "rock and roll" over the last 1800 years, so he's entitled to have a glass to steady his nerves. The First Doctor examines the control room, noting that the Twelfth no longer has Polly around since it's so dusty; the Twelfth Doctor begs him to stop saying things like that as it is insulting to women. The First Doctor then notices the Twelfth's electric guitar and amp, which the Doctor tries to pass off as something a companion left behind. However, the First Doctor notes that it is the only thing in the control room that's not covered in dust, making it the Twelfth Doctor's possession.
Suddenly, the TARDIS shakes violently, prompting the Twelfth Doctor to attempt to take off, only to find that the engines are unresponsive. Looking upwards out of the TARDIS doors, he sees large metal claws pulling the TARDIS upwards. Once the TARDIS has stopped moving, the Twelfth Doctor instructs his predecessor to confront their captors. A humanoid glass figure seated at the top of a staircase speaks to the Doctor, addressing him as "The Doctor of War." The figure requests the return of the Captain in exchange for a friend of the Doctor. Much to the confusion of the First Doctor, Bill then exits one of the corridors. The Twelfth Doctor quickly exits the TARDIS to hug her, before slowly pulling away, drawing his sonic screwdriver, and scanning Bill. To her surprise, the Twelfth Doctor demands that she proves herself to be real, as he believes Bill to have sacrificed herself to defeat the Cybermen. Bill insists she is her real self, explaining how Heather had saved her. The Twelfth Doctor asks what happened after Heather saved her and where Heather is now. Bill struggles for an answer.
The Twelfth Doctor decides to confront his captor directly and runs up the staircase. He is slowly followed by his younger self, who questions the need to move so fast. They find an empty chair with several panels behind it. The First Doctor takes to observing the panels, commenting on their extraterrestrial origin. He turns to his older self, his eyeglass dropping from his eye as he notices the Twelfth Doctor wearing sunglasses to scan the panels. They turn to the chair, where a woman made completely of glass materialises. While the Twelfth Doctor scans the panels with his sonic screwdriver, the original Doctor looks more closely. He berates the Twelfth Doctor for not noticing the asymmetrical features of the woman's face, blaming his use of the sunglasses instead of his eyes. The Twelfth Doctor shyly agrees, and his younger self throws the sunglasses to the ground.
The Testimony proceeds to explain its desire for the Captain back in exchange for Bill, insisting the Doctors return him to them. The Captain, having heard the conversation, exits the TARDIS. He declares they let him be taken, not wanting any harm to come to Bill because of his cowardice. However, the Twelfth Doctor disagrees. Picking up his sonic sunglasses, he races down the stairs, remarking he will find out what the Testimony's purpose is and he will stop it if he doesn't like it. The First Doctor once more berates him for revealing his plan, stating he hasn't a clue who his future self is supposed to be. The Testimony, in an effort to ruffle the First Doctor, reveals the history he is destined to create as a "Doctor of War" by showing how his future incarnations will engage in various battles, which perplexes him.
The Twelfth Doctor presses on with his plan to escape, using the sonic screwdriver to activate the crane which pulled the TARDIS up to take them down, the team jumping onto the chains to escape as well. The Testimony refuses to let them escape, halting the chains and pulling the TARDIS back into the ship. However, as they are a safe distance from the ground, the Twelfth Doctor instructs everyone to jump to the ground.Bill expresses concern about what they will do without the TARDIS but the Doctors reveal they have another, younger version, at their disposal.
They head to the First Doctor's TARDIS, swiftly entering. As she does so, Bill comments on how much smaller it is, causing the Twelfth Doctor to briefly observe the windows before insisting his younger self take off into "deep space, anywhere". While in flight, the First Doctor insists Bill clean the TARDIS only for the Twelfth Doctor to distract him by pointing out the astral map. The Twelfth Doctor uses the sonic sunglasses to access the data banks noting what his predecessor said earlier before placing the shades on the First Doctor. Befuddled, the Doctor asks why he must wear them only for his successor to remark on how much he loves it before taking them back.
The Twelfth Doctor quickly realises the databanks are rather scarce, given the TARDIS is still young. To compensate, he lands the TARDIS at the centre of the universe, Villengard, impressing his younger self at how easily he did such. While searching the area, the Captain is attacked by a creature with multiple little green legs but they save him, both Doctors recognising the creature as a Kaled mutant. The Twelfth Doctor insists Bill wait in the First Doctor's TARDIS to look after the Captain, but Bill blasts him by calling him a "stupid bloody arse", leading to the First Doctor to threaten her with a "jolly good smacked bottom", much to the Twelfth Doctor's embarrassment. Bill tells the Twelfth Doctor to come back alive, to which he replies; "Be here when I do."
The First Doctor fetches the Captain another brandy, realising that was why his successor was missing some. He soon leaves to join his older self, while Bill looks after the Captain, but when she grabs the brandy, her hand is revealed to be glass. While outside on Villengard, the two Doctors rest, discussing their respective regenerations. The Twelfth Doctor remarks they have yet to change because they are in a "state of grace", though he himself finds his body starting to deteriorate. He asks why his younger self halted the regenerative process, unable to remember himself. The First Doctor admits he is "afraid" of regenerating. Before the Twelfth Doctor can answer the question himself, they suddenly come under attack from a creature in a nearby tower, and only stops when the Twelfth Doctor asks the creature to scan him, announcing; "I'm dying!", before going into the tower. He tells his younger self to wait outside to which he begrudgingly agrees.
The First Doctor observes the area, finding the remains of a Dalek casing. He inspects it as Bill sneaks up on him and begins asking why he ran away. The Doctor insists she return to the Captain but Bill insists, asking what he was running to. Interested by the question, the First Doctor responds that he left to discover why good always defeats evil. Bill suggests it might be because of "some bloke" though the First Doctor doubts such. Bill hugs him, thanking him for his efforts. However, when she pulls away, the First Doctor realises she is a glass avatar.
Alone, the Twelfth Doctor meets with the rogue Dalek Rusty, who has taken refuge from the other Daleks hunting it. He remarks on how he is a "good Dalek" though Rusty continues to fire at the Doctor. The Twelfth Doctor decides to come to a truce to which Rusty agrees by disarming his gunstick. Given access to the Dalek Hivemind, the Doctor learns that the pilot and its ship, known as Testimony, were created on New Earth, designed to extract people from their timelines at the moment of their death, and archive their memories into glass avatars. "Bill" is one such avatar, created from her memories. Time suddenly freezes again, the First Doctor and Bill entering the room. Although disappointed at seeing no evil to fight, the Doctors agree to return the Captain to his timeline.
Upon doing so, the Captain asks the Doctors to keep an eye on his family, introducing himself as Archibald Hamish Lethbridge-Stewart, an ancestor of the Doctor's close friend the Brigadier. The First Doctor assures he will do so, the Twelfth Doctor confirming they did. The Testimony remarks the Captain will not remember the incident and a perception filter will ensure the Doctors are not noticed once time restarts. As time resumes, the Doctors watch as soldiers on both sides begin singing "Silent Night" in their respective languages. Soon, each side disarms their weapons and enters the battlefield, leading the Captain and the German soldier to withdraw their weapons and make peace. The Twelfth Doctor explains to the First that he deliberately shifted the Captain's timeline to the start of the Christmas truce, to ensure his life would be spared. The First Doctor is amazed at the fact that his successor altered time to save both men, leading the Twelfth Doctor to explain how "generally the universe isn't a fairy tale, but that's where we come in" and that "it never hurts, a couple fewer dead men on a battlefield." This causes the First Doctor to finally understand what being the "Doctor of War" really means.
With the Captain saved, the two Doctors observe the truce for a time and eventually shake hands. As they do, both Doctors' hands start glowing with regeneration energy. The First Doctor declares that he is finally ready, but the Twelfth Doctor states that his predecessor will have to find out what the Twelfth Doctor decides to do "the long way round." The First Doctor returns to his TARDIS and sets the controls to return him to the South Pole in 1986. Overcome by his regeneration, the First Doctor declares "here we go, the long way round" and collapses as his TARDIS returns to the South Pole. Shortly afterwards, the First Doctor regenerates into a much younger second incarnation.
As the soldiers play football, draw and spend the day together, the Twelfth Doctor watches on, saluting the Captain - who briefly bypasses the perception filter, but dismisses him and returns to his trench. Now alone with Bill's avatar, the Doctor adamantly contends she is not the genuine Bill, only for her avatar to explain that memories are what define a person. To help him understand, the avatar restores the Doctor's memories of Clara Oswald then turns into her. Clara greets the "stupid old man", telling him that forgetting her was rude. The Doctor laughs with joy that she's back in his head. Clara reverts back to Bill, who asks the Doctor if he now understands the importance of memory. They are joined by Nardole's avatar who joins Bill in asking the Doctor not to allow himself to die. The Doctor refuses to give the avatars testimony of his life, stating he must be left alone to face his end. They respect his wish and leave after he embraces them both.
The Doctor returns to the TARDIS. He laments how the more he saves the universe, the more it seems to be in need of saving. He briefly argues with the TARDIS, conceding that "they would get it all wrong without me" as he decides to regenerate, saying "One more lifetime won't kill anyone. Well, except me", but not before relaying advice to his next incarnation. He collapses as he does so but manages to return to his feet. Finally ready, the Twelfth Doctor utters his last words "Doctor... I let you go". With that, he takes a last quick gasp for air before he regenerates, the process so violent that the energy ignites the console room as his face and piercing blue eyes start changing, morphing into a younger-looking and rounder one with hazel eyes.
Smoke fills the console room and the Twelfth Doctor's wedding ring falls from a finger it no longer fits. Once the smoke clears, the Thirteenth Doctor stands in silence for a moment, before grabbing one of the console's monitors. Using its reflective surface, she studies her new appearance in stunned wonderment, realising that she has now become female for the first time. Her face cracks into a wide, ecstatic grin as she as exclaims "Oh, brilliant!" at the discovery. Excited, she presses a button on the console. Upon doing so, the TARDIS suddenly suffers multiple failures and, hanging thousands of feet above the Earth, sharply jerks causing the doors to face the ground. The Doctor tries to hang on but the doors open threatening to suck her out. As the Doctor grabs the console, the ship continues to shake, sending all of her books and papers flying out the open doors. The Doctor tries to close the doors, but the time rotor shatters and the panel she's holding onto breaks away, sending her falling out of the ship. In freefall towards the Earth below, the Doctor watches the inside of her TARDIS become swamped by flames before vanishing from sight as she plummets through the clouds...

Story notes
- Though brief, this was the debut performance for Jodie Whittaker as the Thirteenth Doctor. Her scene was written by the incoming showrunner Chris Chibnall.[1] Her first line in the role was: "Oh, brilliant."
- The cinematic, DVD and Blu-ray releases featured two documentaries: The End of an Era, a retrospective and behind-the-scenes look, before the showing, and Twice Upon a Time at the end, an in-depth look into the making of this Christmas special.
- Twice Upon a Time features a "Previously on Doctor Who..." sequence saying "709 Episodes ago" and showing footage from TV: The Tenth Planet with William Hartnell, Anneke Wills and Michael Craze as the First Doctor, Polly Wright and Ben Jackson respectively. This scene makes use of two aspect ratios. The footage reframes from 4:3 black and white to 16:9 colour, slowly morphing Hartnell into David Bradley, and Lily Travers and Jared Garfield then appear as Polly and Ben, reenacting missing segments on Snowcap from said episode. Following the First Doctor's return to his TARDIS, the episode briefly goes back to 4:3 black and white after Bradley's Doctor is seen lying on the floor unconscious, cutting to the original regeneration from Hartnell into Troughton, and visually bookending the First Doctor's involvement in the narrative.
- The Tenth Planet Episode 4 is the 133rd episode. Twice Upon a Time taking place 709 episodes later would make it the 842nd episode. However, the actual number of Doctor Who episodes has never been clear due to the lack of a distinction between traditional, regular-length adventures and mini-episodes and prequels. The Time of the Doctor was promoted as what would be the 800th episode if only the traditional definition is used. Under this rule, Twice Upon a Time would actually be only 707 episodes later. The Twelfth Doctor only appeared in two mini-episodes or prequels - Prologue and The Doctor's Meditation. Were they to be counted, Twice Upon a Time would indeed be 709 episodes later. However, this would still require the traditional definition of "episode" to apply to TV stories before The Time of the Doctor.
- This story features a rare instance in which actors that only appeared through use of archive footage were also credited. Another notable instance of this happening is TV: The Day of the Doctor. Unique to this instance, the title of the story from which the archive footage is taken is also included in the credits.
- William Hartnell's credit has been changed from "Dr. Who" to "The Doctor."
- Rachel Talalay had actually shot a number of scenes from The Tenth Planet, with a complete set reconstruction, recast characters, and the series 10 Mondasian Cybermen. She said in an interview that she tried to make both the set, and the cinematography, as accurate to the original scenes, and original production values, as much as possible. She did admit to having fun with some parts of the set in particular, and embellishing with a "60s feel", and noted that some details of the action had to be invented. These scene recreations were not used in the final edit of Twice Upon a Time; the original footage was used in its place. However, these specially shot re-tellings were shown in the cinema feature DOC: Twice Upon a Time.[3]
- The First and Twelfth Doctors meeting also features the scene acted out differently in TV: The Doctor Falls and Twice Upon a Time, similar to how episodes in the 60s reshooting the prior scene’s cliffhanger, often resulting in little differences. The same situation also occurred when TV: The Runaway Bride followed the TV: Doomsday cliffhanger 11 years prior.
- The recreated Hartnell TARDIS interior set actually included props from the original set in the 1960s. As told by Mark Gatiss, these included the brass pillars, which are indeed the brass pillars from way back in 1963. Other aspects of the set were recreated.[3]
- The Twelfth Doctor's regeneration has a new visual effect, and even sound effect, to those used previously in the BBC Wales series. Resembling slow travelling, elongated golden lightning. It is the first regeneration for the Doctor, since the Seventh Doctor's in 1996, to use an effect which is visually distinct from that seen in The Parting of the Ways, with the Ninth Doctor up to The Doctor Falls.
- Toby Whithouse, with his performance here as the German soldier, is the fifth (and currently last) person to have both written for and acted in Doctor Who. The others being Victor Pemberton, Derrick Sherwin, Glyn Jones and Mark Gatiss. Though Whithouse and Gatiss are the only two who have written and acted in the revived series and are the only two to have written multiple stories. Gatiss and Whithouse were the most prolific writers during Steven Moffat's time as showrunner (excluding Moffat himself).
- Mark Hedges, 1st assistant director, last worked on a DWU programme on Invasion of the Bane, the very first episode of The Sarah Jane Adventures in 2007. Gareth Meirion Thomas, sound recordist, last worked on Torchwood: Miracle Day in 2011. This was the first, and so far[update] only, Doctor Who credit for both crew members.
- The First Doctor's amazement and confusion about the Twelfth Doctor's sonic screwdriver would appear to contradict PROSE: Venusian Lullaby, which features the screwdriver used by the First Doctor.
- This is the third consecutive regeneration story to include the word "time" in the title, following The End of Time and The Time of the Doctor.
- This is the second multi-Doctor story to feature a regeneration and the first in which it is the current incarnation of the Doctor who is shown to regenerate.
- Nikki Amuka-Bird is credited as "Helen Clay" on-screen, and as "The Glass Woman" in Radio Times.
- When Bill's glass avatar and the Doctor talk and she restores his memories of Clara Oswald, the music from The Husbands of River Song when the Doctor and River were on a date before the Singing Towers of Darillium plays.
- On the last day of filming, Mark Gatiss brought in the jacket that Jon Pertwee wore in TV: Planet of the Daleks. It was featured hanging from a stand in the background in the Twelfth Doctor's TARDIS during the regeneration scene.[4] He also published a Behind the scenes picture of Capaldi wearing the jacket.[5]
- Nardole having invisible hair was already jokingly stated by Steven Moffat in a BBC post-episode interview. There he also stated that Nardole was the only one able to see it through his glasses and that it was purple.[6] Matt Lucas had been aware of the invisible hair, but not the glass nipples.[3]
- The Twelfth Doctor's final lines about his name and how humans would understand it are directly taken from a theory Capaldi stated at a press screening interview of The Pilot.[4]
- The Twelfth Doctor's line "never, ever eat pears" is a tweaked version of the one in a hidden scene in TV: Human Nature by the Tenth Doctor. It was also said in TV: Hell Bent by the Twelfth Doctor.
- This is the first regeneration story in the revived series without any direct connections to the Last Great Time War.
- The idea of the First Doctor looking wrong mid-regeneration can be paralleled to the Second-and-a-Halfth Doctor during the events of NOTVALID: Devious.
- This is the third televised multi-Doctor story, after TV: The Two Doctors and Time Crash, that is not an anniversary special. It's also the first televised Christmas special to also be a multi-Doctor story.
- Time Crash was also written by Steven Moffat.
- The Twelfth Doctor's regeneration is the second on-screen regeneration in which the participant changes gender as a result, following that of the General in TV: Hell Bent.
- During the title sequence, the actor credits zoom further up the screen before fading out than in previous episodes.
- The episode marks the first time since the series's revival that the Doctor is not in the TARDIS while it is crashing, after regenerating. Instead, it is the first time the TARDIS's gravity has malfunctioned and caused it to drop the Doctor out.
- Jenna Coleman's appearance had to be recorded separately as she was too busy working on Victoria. She shot her scene in front of a green screen at the Top Gear office.[7]
- The First Doctor's assertion that "I can't go through with it. I will fight it. I will not change." as he walks through the snow at the start of the episode is a line that was originally cut from the regeneration scene at the end of The Tenth Planet, according to the production subtitles available on the The Tenth Planet DVD release.[source needed]
- This is the second TV story to depict more than one regeneration on screen, following Planet of the Spiders. While Planet of the Spiders featured two different Time Lords regenerating, this story depicts two instances of the same Time Lord regenerating.
- This is currently the only TV story in which both male and female incarnations of the Doctor appear.
- For the First Doctor's TARDIS, the wall with photographs of roundels was replaced with the wall behind the Curator from TV: The Day of the Doctor.[8]
- When the Doctor's ring falls off her finger, only the secondary band of the ring was in the shot. This was because the first band of the ring was Peter Capaldi's wedding ring.
- The Twelfth Doctor somewhat breaks the fourth wall when he says "In fairness, they left out all the jokes"; this is a nod to whoever compiled the archived footage of the past versions of the Doctor to be played by the Testimony only used scenes were the Doctor was being cold and violent.
- This is the first regeneration story and the first multi-Doctor story to be directed by a woman.
- This is the first multi-Doctor story to explicitly take place during a previously broadcast TV story from the earlier Doctor's perspective, though footage from the unbroadcast serial TV: Shada was used in TV: The Five Doctors.
- This was the last episode contributed to by production designer Michael Pickwoad before the announcement of his death in August 2018.

Production errors
- Bill's shirt changes constantly throughout the entire episode, from the rainbow shirt that was seen in Smile, to a new shirt which we have not seen before.
- However, this could be attributed to the fact that this version of Bill is a collection of her memories and not her physical self.
- Nikki Amuka-Bird fluffs a line: “Step out of the caps-ul.” She should have said “Cap-sule.”
- When examining the glass woman, the Twelfth Doctor’s right hand is in line with his waist. Next shot and his hand is down his side. In the next shot, his left hand is next to his waist.
- When the Captain is taken from the World War One battlefield he has his revolver in his hand. After he falls to the ground at the South Pole, the gun is in his holster and he has to draw it again.
- At around the 39-minute mark, the date on the electronic display reads 5,000,000,012 & the Doctor says year five million & twelve. 5,000,000,012 is five billion & twelve.
- A few times throughout the episode, the doors of the first Doctor's TARDIS open as he approaches them even though he didn't operate the door control on the console.
- After the Captain requests a favour from the Doctors, the First Doctor can be heard saying "Oh, anything. Name it," but his mouth is not actually moving after the word "oh."
- In the Christmas scene on the battlefield, fire is seen in several places. In the shots where objects are in front of the fire, the smoke is seen to rise in front of the object, despite the fire being behind.
- When the medics run with the stretcher, it is brown and has a large stain on it. But when the soldier is on it, it changes to black.
- During the scene in which the soldiers are playing football, the shot is flipped. This is visible due to the soldier's uniforms.
- The Twelfth Doctor begins regeneration with his back to the stairs, but immediately following regeneration, the Thirteenth Doctor is standing at a different angle and is further away from the stairs.
- When the Doctor catches herself from falling through the TARDIS doors with her foot, her boot briefly changes to a different shoe.
- In the shot where the Doctor falls through the TARDIS doors, the bottom-right section of wall has clearly been digitally extended on the last frame.
Myths
- The Twelfth Doctor would be killed. The Twelfth Doctor was killed in the previous story, he just refused to regenerate then.
- Because the opening was set in the events of The Tenth Planet, Cybermen would appear. Although this was technically true, they only appeared through the use of archival footage from said story.
- A full recreation of several scenes were originally filmed for this purpose.
- Carole Ann Ford would return as Susan Foreman. This was proven false.
- The Captain would turn out to be Gilbert MacKenzie-Trench, the man who created the iconic police box design. The Captain was revealed to be Archibald Hamish Lethbridge-Stewart, an ancestor of the Brigadier.
- The Doctor would regenerate while falling. The Doctor fell out of the TARDIS after regenerating instead.
- According to the Daily Mirror, this story would see the last day of the Time War from the perspective of the First Doctor and the Twelfth Doctor. This was proven false.
- Matt Smith would return as the Eleventh Doctor. This was proven false, although archive footage was used of all of the Doctor's incarnations up to the Twelfth by the Testimony to prove to the First Doctor that the Twelfth Doctor was indeed his future incarnation.
Continuity
