The Power of the Doctor

"The Power of the Doctor" is the third and final of the 2022 specials of the British science fiction television programme Doctor Who, and was broadcast on BBC One on 23 October 2022. The episode was ordered for the centenary of the BBC's launch, airing five days after. It was written by Chris Chibnall, and directed by Jamie Magnus Stone.

Jodie Whittaker stars in her final regular appearance as the Thirteenth Doctor, alongside Mandip Gill and John Bishop as her companions Yasmin Khan and Dan Lewis, respectively. The episode also features the return of Jacob Anderson as Vinder and Jemma Redgrave as Kate Stewart, both of whom last appeared in the thirteenth series; Sacha Dhawan as the Master and Patrick O'Kane as Ashad, both of whom last appeared in the twelfth series; as well as previous companions Janet Fielding as Tegan Jovanka and Sophie Aldred as Ace, who last appeared in the twenty-first and twenty-sixth and final seasons of the show's original run, respectively. The ending of the episode features David Tennant, who previously portrayed the Tenth Doctor, appearing as the Fourteenth Doctor.

Plot
The Thirteenth Doctor and her companions intervene in a CyberMaster attack on a bullet train in space, but are unable to stop the CyberMasters escaping from the train with a child. After nearly being killed boarding the train, Dan develops a sense of his own mortality and parts with the Doctor to get back to living his life. A rogue Dalek contacts the Doctor, offering information about a Dalek plot to destroy humanity. The Doctor tracks the child to a second moon that has appeared in the sky over 1916 Russia. In reality, it is a planet that has been turned into a cyber-conversion facility by the CyberMasters. The Doctor and Yaz find the child from the train imprisoned on the planet, and discover it is actually an enslaved energy being called a Qurunx using a perception filter.

The Doctor's former companions Tegan and Ace investigate the abduction of a dozen of the world's leading seismologists and the addition of Rasputin's face to fifteen famous paintings. Kate Stewart invites the Doctor to UNIT's headquarters to meet Tegan and Ace and discuss their findings. The Doctor clarifies that the new face in the paintings is actually that of the Master.

The Doctor goes to confront the Master at a seismology conference in Naples, where he reveals he has killed the missing seismologists by miniaturisation. The Doctor learns the Master and his CyberMasters have allied with the Daleks to end humanity in the present by triggering eruptions from every volcano on Earth simultaneously. The Doctor meets the rogue Dalek, discovering the other Daleks allowed it to contact her in order to capture her, which they do after killing the traitor. Meanwhile, the Doctor's former ally Vinder crash-lands on the Cyber planet.

Under arrest at UNIT headquarters, the Master reveals he had sent a miniaturized model of the dead Ashad to Tegan, who assumed it was a warning from the Doctor and thus kept it on her person. The figurine enlarges and acts as a Russian doll, bringing a cloned Ashad and a large number of Cybermen into UNIT HQ, freeing the Master. The Daleks take the Doctor to the Master in 1916 Russia, where he has been posing as Rasputin. The Master uses Gallifreyan technology and the Qurunx to force the Doctor to regenerate into the Master.

In her mind, the Doctor encounters manifestations of her First, Fifth, Sixth, Seventh and Eighth incarnations, who inform her it may be possible to undo the forced regeneration with outside help. An AI program the Doctor created, using images of the Fifth, Seventh and Thirteenth Doctors, leads Ace to meet with former companion Graham and destroy the Dalek volcano machine, Tegan to destroy the Cyberman converter and CyberMasters in UNIT HQ, and Yaz and Vinder to trick and capture the Master with a hologram of the Fugitive Doctor. They also cause the CyberMasters to regenerate, harnessing the energy to undo the Doctor's forced regeneration.

Defeated, the Master mortally wounds the Doctor with the Qurunx's energy beam, triggering her regeneration before seemingly dying of his own injuries without regenerating. The Doctor takes Yaz home and departs alone. Yaz attends a support group of former companions including Graham, Dan, Kate, Ace, Tegan, Ian Chesterton, Jo Jones and Mel Bush. The Doctor travels to a cliff where she regenerates into the Fourteenth Doctor, who is alarmed to discover his new incarnation is physically identical to his tenth incarnation.

Development
"The Power of the Doctor" was written by showrunner and executive producer Chris Chibnall and directed by Jamie Magnus Stone.

Sacha Dhawan, who portrays the Master, influenced the storyline of the episode. Chris Chibnall asked him 'If you were to come back, what would you like to do', to which Dhawan replied that he wanted to explore the theme of the Master's disguises. This ended up being a major part of the episode's story.

After the first two specials were produced as part of the eight episodes ordered for the thirteenth series, a third feature-length special was later ordered to coincide with the centenary of the BBC and serve as Whittaker's regeneration episode. The BBC described the final episode as an "epic blockbuster special".

Casting and details of the centenary special, without revealing the title or airdate, were released after "Legend of the Sea Devils" concluded.

The title of the special was announced on 14 September 2022.

Casting
Jodie Whittaker stars as the Thirteenth Doctor in her final regular episode, alongside Mandip Gill as Yasmin Khan and John Bishop as Dan Lewis. The BBC announced Whittaker and Chibnall's departures from the series in July 2021. Gill confirmed that the special would be her final regular appearance in the series on 3 May 2022.

A trailer for the special was released in April 2022, and confirmed the return of Jacob Anderson as Vinder and Jemma Redgrave as Kate Stewart, both of whom last appeared in the thirteenth series. The Master, played by Sacha Dhawan, and Ashad, played by Patrick O'Kane, who both appeared in the twelfth series, also return. The special also sees the return of former companions Tegan Jovanka, Ace and Graham O'Brien portrayed by Janet Fielding, Sophie Aldred and Bradley Walsh, respectively. The Daleks and the Cybermen also appear.

In cameo roles, the First, Fifth, Sixth, Seventh, Eighth and Fugitive Doctors appear. The First Doctor is portrayed by David Bradley, who previously portrayed the character in the episodes "The Doctor Falls" and "Twice Upon a Time" (both 2017), as well as portraying the original First Doctor actor William Hartnell in the bio-drama An Adventure in Space and Time (2013), while the others are played by their respective original actors: Peter Davison, Colin Baker, Sylvester McCoy, Paul McGann and Jo Martin. According to Chibnall, Fourth Doctor actor Tom Baker was invited to appear in the episode but was unavailable. David Tennant, who previously portrayed the Tenth Doctor, makes a brief appearance as the Fourteenth Doctor.

Former companions Ian Chesterton, Jo Jones and Mel Bush, portrayed by William Russell, Katy Manning and Bonnie Langford, respectively, also appear in brief cameos. With this appearance, Russell, who last appeared as Ian in "The Planet of Decision", the final episode of The Chase, in 1965, achieved the Guinness World Record for the longest gap between TV appearances. Anneke Wills was also approached to reprise her role as Polly Wright but chose not to return.

Filming
"The Power of the Doctor" was filmed throughout September 2021, directed by Jamie Magnus Stone, concluding on 13 October 2021. Tennant's appearance was filmed on 13 May 2022, directed by Rachel Talalay. Returning showrunner Russell T Davies scripted the incoming Doctor's appearance, with his first line, a reference to his first words as the Tenth Doctor being suggested by Tennant himself. The background of the regeneration scene, where the Doctor lands the TARDIS atop a cliff and looks out over the sea, was filmed by drone at Durdle Door in Dorset. The Lulworth Estate was not informed of the context of the scene when granting permission for the shoot, and after the episode's broadcast expressed concern that it would encourage viewers to place themselves in danger.

Among the musical cues heard in the episode is "Rasputin" by Germany-based pop and Eurodisco group Boney M, originally released in 1978; the Master, as played by Sacha Dhawan, portraying the Russian cleric, uses the song to accompany his impending transformation. Dhawan noted that he was given only "one or two takes" for the set piece, "and we didn't have that long to shoot it."
