The Power of the Doctor (TV story)

The Power of the Doctor was the 2022 Doctor Who Centenary Special, broadcast as part of the BBC 100 celebrations. Marking the end of Jodie Whittaker's tenure as the Thirteenth Doctor, this was also the final entry to be penned by Chris Chibnall as showrunner. It saw the return of the Spy Master and Ashad, following their apparent demise at the end of The Timeless Children, and marked the first time the Master, the Cybermen and the Daleks all worked together onscreen.

Several past Doctor Who companions returned for the special, most prominently Janet Fielding as Tegan Jovanka, Sophie Aldred as Ace, and Bradley Walsh as Graham O'Brien. Appearing in cameo roles were Bonnie Langford and Katy Manning as Melanie Bush and Jo Jones, with Langford returning to the television series for the first time since her exit in Dragonfire, and Manning returning to for the first time since her character's last appearance in The Sarah Jane Adventures story Death of the Doctor. Notably, joining Langford and Manning in a cameo role was William Russell as Ian Chesterton, marking the character's first onscreen appearance in the television series since The Chase in 1965, which Guinness World Records marked as the longest gap between appearances of a character still played by their actor.

Also returning in mental manifestations of the Doctor’s consciousness were David Bradley, Peter Davison, Colin Baker, Sylvester McCoy and Paul McGann, all reprising their roles as their respective Doctors, and Jo Martin as the Fugitive Doctor.

The story notably marked the first onscreen retro-regeneration, after the Master taking over the Doctor's existence with his own regeneration, something he failed to do before to the Eighth Doctor, with this brief possession being the first forced regeneration since The War Games and causing the possessed Doctor to take on the Master's appearance. With the Master using the name of the Doctor, this technically makes Sacha Dhawan the first actor to have portrayed both the Master and the Doctor onscreen in the same story. The special also marked the second time the Doctor was seen to regenerate more than once within the same television story, following Twice Upon a Time, if one was to count the Timeless Child as a different entity from the Doctor, who underwent no less than six regenerations in The Timeless Children.

In a twist, the special introduced Tenth Doctor actor David Tennant as the Fourteenth Doctor in its closing moments, marking the first time on-screen that the Doctor regenerated into a different incarnation with the same appearance as a previous one, after such a phenomena was forshadowed by the Curator in The Day of the Doctor.

Synopsis
Famous paintings have been mysteriously defaced around Earth, seismologists have gone missing, there is strange activity occurring in volcanoes and across the stars a bullet train is pursued by CyberMasters. The Doctor doesn't understand how it all connects. All she has is a message from an old enemy - "this is the day you die"...

Plot
The Doctor and her companions rescue a space-going bullet train from a Cyberman attack, but Dan is nearly killed during the escapade. The Cybermen manage to escpe with the train's cargo, which seems to be a young human child. Having developed a sense of his own mortality, Dan parts ways with the Doctor in order to get back to living his life. A renegade Dalek contacts the Doctor, claiming to have decided the Daleks need to be destroyed due to them being a perversion of the Kaled race. It offers information about a plot to destroy humanity, promising to communicate a time and location. Kate Stewart also contacts the Doctor and informs her that various pieces of famous artwork have been defaced with the Master's visage and several seismologists abducted.

After briefly reuniting with former companions Tegan Jovanka and Ace McShane, the Doctor confronts the Master and learns he and his CyberMasters have teamed up with the Daleks and enslaved the child the Cybermen captured, who is in reality an energy being called the Qurunx, to end humanity by setting off eruptions from all volcanoes on Earth simultaneously. The Doctor meets the renegade Dalek, but discovers it had been allowed to contact her in order to lure her out, leaving the Daleks including their commander to kill the traitor and capture her.

The Master is arrested by UNIT, but reveals he sent a miniaturised Ashad to Tegan, pretending to be the Doctor. The miniaturised Ashad enlarges and acts as a portal to bring a fleet of Cybermen into UNIT HQ, freeing the Master. The Daleks take the Doctor to 1916 and hand her to the Master, who uses Gallifreyan technology to force her to regenerate into him. An AI program the Doctor created, taking the images of the Fifth, Seventh, Fugitive, and Thirteenth Doctors, leads Ace to meet with fellow former companion Graham O'Brien and destroy the Dalek volcano machine, Tegan to destroy the Cyberman converter created in UNIT HQ and destroy the CyberMasters before they convert Kate, and Yaz and previous ally Vinder to capture the Master and force him to undo the Doctor's transformation. Defeated, the Master mortally wounds the Doctor with the Qurunx' energy beam, causing her to begin her regeneration.

The Doctor takes Yaz home. Yaz meets with a group of former companions including Graham, Dan, Ace, Tegan, Ian Chesterton, Jo Jones, and Melanie Bush. The Doctor finds a cliff to regenerate upon. She says a fond farewell to her current self before saying to her next self “Tag, you’re it” and regenerates into her next incarnation. After the explosive regeneration finishes, resulting in a male incarnation once again and also a change in his clothes, the Fourteenth Doctor immediately realises something isn't right. By checking his teeth, he realises out loud in a very familiar voice and accent that he actually knows the feeling of his new teeth. Alarmed by this, the newly regenerated Doctor begins to examine his new body. Recognising his new hands before noticing his predecessor's clothing has also completely been altered by the regeneration, the Doctor feels the shape of his new face and discovers to his shock that he has regenerated into a body virtually identical to his tenth incarnation. The new Doctor — or should that be the old Doctor? — can only exclaim in amazement and utter confusion "What? What? What!?"

Story notes

 * This story was created in celebration of the BBC's 100th Anniversary, and had the working title of The Centenary Special.
 * According to Chris Chibnall, this story was filmed in the belief that it was to be the last story of Doctor Who, as he didn't know who would take over from him. It wasn't until after filming that it was announced that Russell T Davies would be returning as showrunner.
 * Jodie Whittaker's half of the regeneration was filmed at Roath Lock in July 2021. The post-regeneration scene with David Tennant as the Fourteenth Doctor was filmed separately at Wolf Studios in Cardiff in May 2022, almost a year later.
 * Jodie Whittaker was pregnant while filming The Power of the Doctor.
 * This story shares filming locations with the Fourth Doctor story The Pirate Planet and the Seventh Doctor story The Curse of Fenric. For the latter, the landowners of the Lulworth Estate threatened to ban the BBC from filming there ever again due to what they described as them being "duplicitous and dishonest" in not describing exactly what the scene would show, potentially encouraging members of the public to put themselves in a dangerous situation, despite filming not actually taking place on top of the cliff itself.
 * Discounting regenerations shown outside of chronological order in The Night of the Doctor and The Day of the Doctor, this is the first Doctor-regeneration story since The Parting of the Ways to not take place on a Winter Special, and the first chronological Doctor-regeneration story since Journey's End to not include the word Time in the title.
 * As of this episode, the Thirteenth Doctor's tenure was able to run for longer than three Prime Ministers governing the United Kingdom (Theresa May, Boris Johnson and Liz Truss), thus making her the first ever Doctor to outlast three Prime Ministers, beating Tom Baker's record of having outlasted two Prime Minsters (Harold Wilson and James Callaghan) and failing to outlast a third (Margaret Thatcher) during his tenure as the Fourth Doctor.
 * This was the first episode to air during the reign of King Charles III, meaning that the Thirteenth Doctor's tenure was the first to cover two monarchs, with Queen Elizabeth II's death occurring on 8 September 2022, a little over a month before the Special.
 * This is the third special to air in UHD, after Revolution of the Daleks and Twice Upon a Time.
 * The new BBC logo returned to the title sequence, having been absent since Eve of the Daleks.
 * This episode is the first to have two actors' names appear at the same time in the title sequence, in this case Sophie Aldred and Janet Fielding.
 * This story marks the first and only appearance of Daleks with standard suction cups in the televised Thirteenth Doctor era following the Reconnaissance Dalek, Defence Drone, Death Squad Daleks and Dalek Executioners, all of which wielded a form of claw manipulator, though a CGI model of a Dalek with a claw makes a cameo.
 * Whilst numerous interiors of the Dalek casing have been shown both on-screen and off-screen, the Dalek traitor notably has the Dalek mutant placed at the bottom of the middle section in contrast to the general placement within the neck section as seen in TV: The Five Doctors, Resurrection of the Daleks, Dalek, The Parting of the Ways, Daleks in Manhattan and The Stolen Earth/Journey's End.
 * The mutant itself resembles that of the Reconnaissance Dalek and its clone army from TV: Resolution and Revolution of the Daleks, respectively, rather than the earlier "New Who" mutant form introduced with the Metaltron in Dalek.
 * The Dalek gunstick as used in this story inexplicably alternate between the standard blue beams and orange beams similar to the Imperial Daleks in Remembrance of the Daleks.
 * The Master refers to his plans as the Master's Dalek Plan. This is a reversal of the 1965 story's episode title The Daleks' Master Plan, and was previously done in the title of a Big Finish Productions audio story featuring Derek Jacobi's War Master, The Master's Dalek Plan.
 * Fourth Doctor actor Tom Baker was invited to take part in the Special as one of the Guardians of the Edge, but was unavailable, with Chibnall explaining "''We asked Tom, but sadly he could not do it. He was not available. Such a shame."
 * The song Rasputin by Boney M is played during the scene where the Master, disguised as Rasputin, dances and powers on the conversion planet. This isn't the first time the Master has danced to a piece of music: he last danced to Voodoo Child by Rogue Traders in The Sound of Drums and I Can't Decide by The Scissor Sisters in Last of the Time Lords.
 * Sacha Dhawan improvised the Master's dance during the Rasputin song scene and he noted that he was given only "one or two takes" for the set piece, "and we didn't have that long to shoot it."
 * Anneke Wills was invited to return as Polly Wright to be part of the companion support group, but was unavailable, saying "I heard it was quite brief so I’m glad I stayed and did my brambles instead.".
 * This story is the first non-archive, televised appearance of William Russell as Ian Chesterton since 1965 story The Chase; he had previously appeared in HOMEVID: Ian Chesterton: An Introduction in 1999. With his appearance in this episode, Russell, aged 96 at the time his scenes were shot, became the oldest actor to work on revived Doctor Who. The previous holder of this record was Ysanne Churchman, who was 92 at the time she reprised the role of Alpha Centauri in TV: Empress of Mars.
 * The Thirteenth Doctor's final lines include the words "blossomiest blossom", echoing the phrase "blossomest blossom" from a 1994 interview of, and "daisiest daisy", which the Third Doctor mentioned in his speech about the Hermit in The Time Monster.
 * David Tennant holds the distinction of being the first actor to have portrayed two different numbered incarnations of the Doctor in a mainline story of Doctor Who without needing to fill in for an actor playing the new incarnation, following Sylvester McCoy filling in for the Sixth Doctor during his regeneration scene in Time and the Rani in addition to his main role as the Seventh Doctor, Paul McGann briefly acting as a body double for John Hurt's War Doctor in the closing moments of The Night of the Doctor after the regeneration of his Doctor, Tom Baker and Colin Baker portraying the Curator alongside their original incarnations, and Richard E Grant playing both the Tenth Doctor in The Curse of Fatal Death and the Ninth Doctor in Scream of the Shalka.
 * The end credits changed to groups instead of scrolling. This was last seen in Revolution of the Daleks. The text for the character names and crew roles were also changed to bold, last seen for the title card for The Woman Who Fell to Earth.
 * Mel is listed in the ending credits as "Melanie Bush", marking the first time on television that her surname, which was previously only established in audio and prose, has been used. Likewise, Jo is listed in the ending credits as "Jo Jones", which is the first time she was referred to as such on the credits of televised Doctor Who, with her first time being referred to and credited as such in any television media being The Sarah Jane Adventures story Death of the Doctor.
 * With this episode, all of the current-surviving actors who played the Doctor in the classic series have made an appearance in the revived series.
 * This story featured the largest number of actors to play the Doctor in a single episode, namely eight. The number increases to nine if one counts Sacha Dhawan's portrayal of the Master in the Doctor's body.
 * This is the last story to be composed by Segun Akinola, who joined in The Woman Who Fell to Earth in 2018 after Murray Gold decided to leave the show after 10 years in Twice Upon a Time in 2017.
 * Due to a licensing deal between the BBC and Disney Branded Television to have future Doctor Who stories stream on Disney+, this was the final episode to air on BBC America.
 * Russell T Davies revealed to Doctor Who Magazine #584 that "[he] was very certain that [he] didn’t want David to appear in Jodie’s costume." explaining that his reason for the Doctor's clothes changing during regeneration was to avoid stereotyping "the notion of men dressing in "women's clothes", the notion of drag", describing it as a "very delicate" matter, expressing that "it has to be done with immense thought and respect", and that the media would make it "look like mockery" of that culture, as Tennant is taller than Whittaker.
 * According to Chris Chibnall on the DVD and Blu-ray commentary, the idea that Tegan and Ace became friends was the idea of their respective actresses.
 * David Tennant and David Bradley had previously appeared in Chris Chibnall's Broadchurch, which also featured Jodie Whittaker. They also appeared in Blackpool and Harry Potter and the Goblet of Fire.

Contradictions with expanded media

 * This story touches on the circumstances of Ace leaving the Seventh Doctor's company, an event which was not seen on-screen, but had been recently depicted in the novel At Childhood's End, written by Sophie Aldred herself. However, The Power of the Doctor contradicts At Childhood's End by having Ace meet the Thirteenth Doctor, Yasmin Khan and Graham O'Brien for the first time, though At Childhood's End does establish that Ace's timeline has multiple possible futures.
 * Tegan's claim that she hasn't seen the Doctor since 1984 contradicts the Big Finish audio The Gathering, where the Fifth Doctor catches up with her in 2006 just as she's about to celebrate her 46th birthday. It also contradicts the date given by PROSE: Fixing a Hole, which states she shared an adventure with the Sixth Doctor on 23 February 1985, as depicted in A Fix with Sontarans.
 * Clyde Langer had said that Tegan and Nyssa were a couple in Farewell, Sarah Jane. Here, Tegan mentions having two ex-husbands, but Nyssa isn't mentioned at all.
 * Ace claims the last time she saw the Master, he was "half-cat", referring to Survival, ignoring the New Adventure First Frontier, the Big Finish audio play Dust Breeding and the Titan Comics Crossing the Rubicon. AUDIO: The Light at the End was excused as the story was set in an alternate timeline, which altered Ace's memory of her experience and encounter with the Master in the story.

Details from script release

 * The bullet train pre-credits sequence has many changes:
 * The CyberMasters entered in the wrong carriage because Train Marshal Halaz deliberately shuffled the carriages.
 * On the train, Dan and Yaz reminded the Doctor that she forgot to tell them the plan.
 * When Dan's helmet got hit, his face got suctioned toward the rupture and his nose plugged the gap.
 * Dan's departure speech was completely different, with the Doctor giving a response.
 * During its first meeting with the Doctor, the Dalek traitor revealed more of its background such as identifying itself as an elite biological combat engineer whose mission was to devise strategies to ameliorate any Dalek defeat in battle, its work resulting in a genetic code which was to activate and self-execute Dalek creatures in the event of a threat to Dalek supremacy in battle, causing their casings to flood with toxic radiation and detonate, fatally damaging all enemies within a broad radius.
 * To start the Rasputin song, the original scene had the CyberMasters activate panels on their arms and the Master used an old iPod to play the music instead of the TCE.
 * Originally, three planets were at war instead of two and the devastation would be seen up close.
 * The Eighth Doctor Guardian was seen as a separate figure instead of being part of the one figure in the final version.
 * The original script had the Master arrive in the Tunguska forest in Russia in 30 June, 1908. Additionally it had a whole scene with a Russian woman watching in horror as the "first experiment" with the cyber-planet went wrong and squashed many miles of forest. The Master claimed he sent himself to Siberia as "punishment".
 * Tegan was seen more heavily injured after her fall, with an injured her ankle and wrist, whereas she only had a slight limp in the final version.
 * The feedback was revealed to only have knocked Ashad unconscious and an additional scene showed Ashad wandering the UNIT hallways as the building collapsed around him.
 * The original script had a scene, set after he was returned to his old body, with the Master as Grigori Rasputin meeting with Russian Prince Yusopov, who, in keeping with historical fact, would have "Rasputin" shot and put in a sack by two henchmen to be dumped in the river, only the bullets were not seen hitting.
 * During the companion support group scene in the script the laptop was suggested to be for Martha Jones, Ryan Sinclair or, somehow, Jackie Tyler.
 * The Thirteenth Doctor's final scene in the script was originally different, with the Doctor sitting rather than standing, and her last lines being switched around, with her final words being, "I bet it's going to be brilliant.", echoing back to her first words "Oh, brilliant." in TV: Twice Upon a Time.
 * Due to the fact that Chris Chibnall did not know anything about the future of Doctor Who, the regeneration scene was left open ended, with the last shot being the Doctor mid-regeneration.

Ratings

 * Overnights: 3.71 million
 * Regeneration: 4.04 million
 * Consolidated: 5.30 million

Myths

 * Yasmin Khan would be a victim of the Tissue Compression Eliminator. (This turned out to be false. The rumour started when a promotional picture was released of Sacha Dhawan as the Master holding a tiny figurine resembling Yaz)
 * Dan Lewis would die. (This ended up being false. The rumour came about as no promotional material depicted Dan outside the space bullet train mission)
 * Kate Stewart would either die or be converted into a Cyberman. (Both of these ended up being false. Although she was shown going through the conversion process, which was halted by Tegan)
 * Vinder and Bel were to be revealed as the Doctor's parents. (This was proven false [this rumour had been circulating since "Once, Upon Time"])
 * The Doctor was to regenerate on top of a cliff or drown in the ocean. (Cliff was proven true)
 * The Doctor's regeneration was triggered by being shot by Yaz, who was under the influence of the Master. (This was proven false, although the Master was responsible for the Doctor's regeneration)

(AUDIO: Zagreus)
 * The Doctor makes use of the Holo-Doctor that the Seventh Doctor had once given to Bernice Summerfield. (PROSE: Infinite Requiem)

 * The Doctor places Yaz, Ace, Tegan, Kate, Vinder and Graham to various positions within the TARDIS around its console to be given responsibility to handle a part of the controls to help her save the day, which resembles when the Tenth Doctor showed the Children of Time a part of the TARDIS to help bring the Earth back to where it belongs. (TV: Journey's End)
 * Yaz mentions that she tried to take everyone home, but dropped them off in Croydon instead, calling it "close enough."
