In January 2016,
Steven Moffat announced that he would leave the show after the
tenth series; he was set to be replaced by new showrunner,
Chris Chibnall.
Peter Capaldi confirmed a year later that the tenth series would be his last as well. Following this news, several media reports and bookmakers had speculated as to who would replace Capaldi as the Thirteenth Doctor. Bookmakers' favourites included
Ben Whishaw,
Phoebe Waller-Bridge,
Kris Marshall, and
Tilda Swinton.
Casting a woman The concept of a female Doctor was first mentioned in 1981, when
Tom Baker suggested his successor might be female, after announcing the end of his tenure as the
Fourth Doctor. Producer,
John Nathan-Turner, later discussed the possibility of casting a woman as the
Sixth Doctor to replace the departing
Peter Davison's
Fifth Doctor, claiming it was feasible, but not something he was considering at the moment. In October 1986, during the transmission of
Colin Baker's
final season as the Sixth Doctor, series creator,
Sydney Newman, wrote to BBC Controller,
Michael Grade, with a suggestion that "at a later stage, Doctor Who should be metamorphosed into a woman".
Dawn French,
Joanna Lumley, and
Frances de la Tour, were suggested by Newman in 1986 for the role, but were dismissed by the BBC. Lumley later appeared as a satirical version of the Thirteenth Doctor in the 1999
Comic Relief special,
The Curse of Fatal Death.
Arabella Weir also played an alternative
Third Doctor in the
Doctor Who Unbound Big Finish episode,
Exile. Neither portrayal is typically considered to be within the show's main continuity. Producer,
Jane Tranter, also considered casting
Judi Dench as the
Ninth Doctor. The concept of
Time Lords changing sex upon
regeneration was seeded throughout Moffat's tenure as showrunner. Just after regenerating, the Eleventh Doctor exclaims "I'm a girl?" In the 2011 episode, "
The Doctor's Wife", the Doctor recalls a Time Lord acquaintance known as the Corsair, who had at least two female incarnations. In the 2013 short, "
The Night of the Doctor", the
Sisterhood of Karn offer a dying
Eighth Doctor (
Paul McGann) control over his inevitable regeneration, with "man or woman" being touted as possibilities. The first on-screen cross-gender regeneration was shown in the 2015 episode, "
Hell Bent", in which a white male Gallifreyan general (
Ken Bones) regenerates into a black woman (
T'Nia Miller), who states that her previous incarnation was the only time she had been a man. The most notable Time Lord to have appeared in both male and female forms prior to Whittaker's casting is the Doctor's nemesis,
the Master, portrayed from 2014 to 2017 by Scottish actress,
Michelle Gomez. This version of the character was known as Missy, short for "Mistress". The
tenth series finale, "
World Enough and Time" / "
The Doctor Falls", addresses cross-gender regeneration several times; the Doctor tells his companion
Bill Potts (
Pearl Mackie) that Missy was "his first man-crush", and adds that he is only "fairly sure" he himself was male at the time, although the remark may have been flippant. Two years prior to the announcement of Whittaker's casting, fans and scholars discussed the possibility of a female Doctor and analysed the benefits of such a regeneration.
Casting Whittaker When referring to whether the new Doctor would be a woman, incoming
Doctor Who showrunner
Chris Chibnall originally was quoted in February 2017, as saying, "Nothing is ruled out but I don't want the casting to be a gimmick and that's all I can say". On 14 July 2017, the BBC announced that the portrayer of the Thirteenth Doctor would be revealed after the
2017 Wimbledon Championships men's finals on 16 July 2017. Whittaker was introduced as the Thirteenth Doctor on 16 July and subsequently made her debut in the 2017 Christmas special "
Twice Upon a Time" and starring in the
eleventh series. On Whittaker's casting, Chibnall said, "I always knew I wanted the Thirteenth Doctor to be a woman and we're thrilled to have secured our number one choice. Her audition for The Doctor simply blew us all away." Later on in his statement, Chibnall called Whittaker "an in-demand, funny, inspiring, super-smart force of nature" and said that she "will bring loads of wit, strength and warmth to the role." In an interview with
Tenth Doctor actor and
Broadchurch co-star
David Tennant, Whittaker said she did not grow up watching
Doctor Who and had decided against watching it to prepare for the role, saying: "I started to watch a bit during my audition process and I quickly decided that was not the way for me...It just made me panic...[Chibnall] said to me, 'you're not coming in and playing the Doctor, you're playing the truth of the scene and the Doctor will come out of that'... so, that's what I did." In November 2018, BBC confirmed that the
twelfth series, Whittaker's second series, began production in November 2018. The series premiere aired on 1 January 2020. Whittaker continued on in the role for the
thirteenth series. Whittaker and Chibnall stated they would exit the show following the thirteenth series and
three specials, which aired through 2022. Chibnall said "Jodie and I made a 'three series and out' pact with each other at the start of this once-in-a-lifetime blast. So now our shift is done, and we're handing back the Tardis keys. Jodie's magnificent, iconic Doctor has exceeded all our high expectations." She was succeeded by Tennant as the
Fourteenth Doctor. == Characterisation ==
