The War Doctor is an incarnation of the Doctor, the protagonist of the BBC science fiction television programme Doctor Who. He was portrayed by the English actor John Hurt. Although he precedes Christopher Eccleston's Ninth Doctor in the show's fictional chronology, his first onscreen appearance came eight years after Eccleston's; the War Doctor was retroactively created by showrunner Steven Moffat for productions celebrating the show's 50th anniversary.
Within the programme's narrative, the Doctor is an alien Time Lord from the planet Gallifrey, who is hundreds if not thousands of years old and travels in time and space in his TARDIS, frequently with companions. When the Doctor is critically injured, he can regenerate his body, but in doing so, gains a new physical appearance and with it, a distinct new personality. This plot device has allowed a number of actors to portray different incarnations of the Doctor over the show's long run.
The War Doctor, not so named within the episodes in which he appears, is introduced as the incarnation of the Doctor who fought in the Time War of the show's modern-day backstory. He was created as a result of a conscious decision of the Eighth Doctor, played by Paul McGann, to take up arms and become a warrior; in accepting this duty, the War Doctor disowned the title of "Doctor", and after the war's end is viewed with disdain by his subsequent incarnations, who reclaim the title that the character is known by. In the 50th anniversary special "The Day of the Doctor", however, the Eleventh Doctor played by Matt Smith revises his opinion of this incarnation after revisiting the final moments of the war.
In his original conception of the show's anniversary special, Moffat had written the Ninth Doctor as having ended the Time War. However, he was "pretty certain" that Christopher Eccleston would decline to return to the role, which he did. As he also had reservations about making Paul McGann's Eighth Doctor the incarnation who had ended the war, he created a never-before-seen past incarnation of the Doctor, which allowed him "a freer hand" in writing the story, acknowledging that the success of doing this would be predicated on being able to cast an actor with a significant enough profile.
Costume
In "The Name of the Doctor", Hurt wore a burgundy and ivory scarf in a herringbone style. He also wore a dark brown leather trenchcoat, similar to the Ninth Doctor's black leather peacoat as well as a green brown moleskin waistcoat with a fob watch, dark tan trousers, and charcoal leather gaiters similar to ones worn by the Eighth Doctor; as well as a pinstripe shirt. Costume designer Howard Burden said that Hurt's character was a "dark Doctor" existing between the Doctor's eighth and ninth incarnations.
He was also seen to use a new sonic screwdriver with a scarlet light, closely matching the prop used by the Third and Fourth Doctors. He kept it in a bandolier originally worn by Cass, played by Emma Campbell-Jones, a young pilot and engineer who dies after refusing the Doctor's help due to him being a Time Lord.
Appearances
The War Doctor first appears at the conclusion of the series seven finale "The Name of the Doctor" when the Eleventh Doctor (Matt Smith) and companion Clara Oswald (Jenna-Louise Coleman) are trapped in the Doctor's timeline. Clara believes she has seen all the Doctor's faces, but does not recognise one figure. The Doctor (Smith) tells her that he is yet another version of himself, albeit one who has lost the right to the name of the Doctor; when the figure declares that he did what he did "without choice [...] in the name of peace and sanity", the Doctor, before he and Clara return to the universe, states that the figure did not make his choice in the name of the Doctor.
The War Doctor's origins are given in the mini-episode "The Night of the Doctor", set during the Time War referred to in the series. After the Eighth Doctor (Paul McGann) is killed in a spaceship crash while trying to save an innocent woman, who rejected his efforts because she regards the Time Lords and the Daleks as equally monstrous for the collateral damage inflicted in the war, he is temporarily resurrected by the Sisterhood of Karn (last seen in The Brain of Morbius) and urged to take a stand and join the war. He is offered an elixir designed to trigger a life-saving regeneration into a form of his choice. Feeling the universe has no more need for a doctor, he requests to become a warrior. After regenerating into the War Doctor, he disowns the name of the Doctor, with his new incarnation's first words being "Doctor no more".
