Series 10 (Doctor Who)

Series 10 was the final series of Doctor Who for Peter Capaldi as the Twelfth Doctor and showrunner Steven Moffat.

It introduced Bill Potts as a new companion of the Doctor, with Nardole continuing to travel with him. The series was most noticeable for reintroducing the "Saxon" incarnation of the Master, and the First Doctor. Also seen was the first ever female Ice Warrior on TV and the original design for the Cybermen, only seen beforehand in The Tenth Planet. Alpha Centauri also made a cameo in Empress of Mars. This series was also the first to have an openly gay companion alongside the Doctor on TV, as well as introducing the first female incarnation of the Doctor.

The first confirmation of plans for this series were revealed in the BBC Worldwide Annual Review on 14 July 2015. On 6 November 2015, in an interview with the Radio Times, Steven Moffat confirmed a full series as well as a Christmas special. Series 10 was the last for both Peter Capaldi's Twelfth Doctor, and Steven Moffat as head writer and executive producer of the show.

Overview
The series story arc primarily focussed on and how the Twelfth Doctor made a deal to guard her in a vault for 1000 years. Despite Nardole's protests to not adventure or interact with her while lecturing at St Luke's University, the Doctor desired to change Missy's outlook on life, away from her evil ways. While here, the Doctor met Bill Potts, who strangely went to his lectures despite not studying at the university. The Doctor personally offered to tutor her and, after helping her in an encounter with a mysterious creature, decided to take her on adventures in his TARDIS.

The series concluded with the Doctor's attempts to transform Missy ultimately failing after encountering her predecessor on a Mondasian Colony ship. The Doctor and Bill were killed in battle defending the residents from the Master's Cybermen army while Nardole was condemned to the upper floors to keep defending the children should the Cybermen ever reach them. Bill managed to survive the ordeal after her friend Heather transformed her into sentient oil like her. As for the Doctor, he managed to survive through regeneration, though he temporarily delayed it.

After one last adventure with his original incarnation, the Twelfth Doctor regenerated into a female incarnation. She soon fell from her TARDIS because it malfunctioned, falling to Earth.

Writers
Steven Moffat, as head writer, wrote the series opener The Pilot, episode six Extremis, and the two part finale episodes World Enough and Time and The Doctor Falls. He also wrote the Christmas special for 2017, Twice Upon a Time as Chris Chibnall decided against starting his Doctor's tenure with the special.

Mark Gatiss wrote Empress of Mars for the tenth series. According to Doctor Who Magazine, it was the ninth episode in the series. Jamie Mathieson wrote episode five, Oxygen.

New writer Mike Bartlett penned episode four, Knock Knock. Sarah Dollard penned the third episode, Thin Ice.

Classic series writer Rona Munro, known for the episode Survival, wrote the tenth episode titled The Eaters of Light. This marks the first time a writer of the original series contributed to the revived series. Munro told Doctor Who Magazine that: "Writing Survival was my dream job, but it was a mournful time in the show's history. This has been a very different experience. There's more of everything; people, resources, confidence, success… but the same constantly renewing and indefinable wonder that is Doctor Who," and added, "When I was very small and watching the First Doctor, I had a special cushion known as 'Rona's Doctor Whocushion'. I would hide my face in it when the Daleks or other monsters appeared on screen! The Eaters of Light is my version of other stories that have haunted me for almost as long."

Peter Harness wrote episode seven, The Pyramid at the End of the World and Toby Whithouse wrote episode eight, The Lie of the Land In the magazine's June 2017 issue, Moffat told Doctor Who Magazine that he personally wrote the final draft of episode seven close to filming of the episode's production block.

Directors
The March 2017 issue of Doctor Who Magazine listed all the directors apart from those in the final two episodes, which at the time of printing had not yet begun shooting. Lawrence Gough directed episodes 1 and 2, The Pilot and Smile; Bill Anderson directed episodes 3 and 4, Thin Ice and Knock Knock; Charles Palmer directed episodes 5 and 10, Oxygen and The Eaters of Light; Daniel Nettheim directed episodes 6 and 7, Extremis and The Pyramid at the End of the World; and Class director Wayne Yip directed episodes 8 and 9, The Lie of the Land and Empress of Mars.

On 6 March 2017, Rachel Talalay was announced by the BBC as the director of episodes 11 and 12, World Enough and Time and The Doctor Falls.

Filming
In 2015, production designer Michael Pickwoad said in an interview on the podcast Radio Free Skaro that work on the new series "won't start until well into the New Year", and that he expected to start filming in May. Peter Capaldi said filming would begin "sometime...next year."

Although originally reported as beginning in May 2016, filming commenced on the 20th of June.

To avoid online leaks, the production team used the codeword "Mean Town", an anagram of "Ten Woman", when talking about Bill, casting director Andy Pryor revealed to the Radio Times. This was a reference to the fact that Bill is the companion of series 10.

The working title of The Pilot was A Star In Her Eye.

In the line-up to the beginning of series 10, a bunch of small videos were released with Peter Capaldi's Twelfth Doctor, in which three of these featured a description that Steven Moffat himself used for the Doctor in 2013.

On 24 June, 2017, Benjamin Cook, writer of Doctor Who Magazine, confirmed on that the pre-titles sequence in World Enough and Time was shot two weeks prior to broadcast, during the production of the 2017 Christmas special

At a Live Q&A on 24 June, 2017, after the broadcast of World Enough and Time, Steven Moffat said that the second part The Doctor Falls had not finished filming, leading to a possible delay in the broadcast. Peter Capaldi's final scene on set had been his regeneration scene, just as his first scene in TV: Deep Breath had been him emerging from the TARDIS. By the end of July 2017, Moffat stated that Jodie Whittaker had already filmed her half of the regeneration scene.

Twice Upon A Time was originally rumoured to be titled The Doctors.

Episode notes

 * On 25 May 2017, the BBC announced the episode The Pyramid at the End of the World would air in edited form, with a line of dialogue about terrorism removed. This is in the wake of the preceding Monday's terrorist bombing in a Manchester arena during an concert. The version of the episode broadcast in Canada and the U.S. also contained this edit.
 * It had previously been believed that there was to be a Casualty crossover and this was speculated to be a Children in Need-special. However it now seems that this was to be part of the episode The Lie of the Land, but was cut from said episode.
 * Benjamin Cook, writer of Doctor Who Magazine, confirmed on Twitter, on 24 June 2017 that the pre-titles sequence in World Enough and Time was shot two weeks prior to broadcast, during the production of the 2017 Christmas special Steven Moffat and Rachel Talalay confirmed this on The Fan Show.
 * Due to technical difficulties some viewers watching on BBC Scotland HD lost the sound during watching of the Series 10 finale The Doctor Falls, in the last part of the episode.
 * Steven Moffat, showrunner for this series, used the finale World Enough and Time and (even more so) The Doctor Falls to pay a subtle tribute to former showrunner Russell T Davies, by having the Doctor's last stand take place on Floor 0507 of the colony ship. He explained that RTD's go-to number was always "57".
 * The beginning of Twice Upon a Time features a "Previously" sequence from The Tenth Planet with William Hartnell, Anneke Wills and Michael Craze. The sequence slowly morphs Hartnell into David Bradley, and then Lily Travers and Jared Garfield appear as Ben and Polly, reenacting the missing last bits on Snowcap of said episode. The ending of Twice Upon A Time from the First Doctor's view also starts with Bradley starting to regenerate and the episode slowly morphs back into that of Hartnell's First Doctor regenerating into Patrick Troughton's Second Doctor.
 * This is the first series since Series 6 in which the title sequence appears the same in every episode of the main series.
