Jodie Whittaker
On 16 July 2017, Whittaker was announced as the Thirteenth Doctor in the science fiction television series "Doctor Who"; she is the first woman to play the title role. She had previously worked with incoming "Doctor Who" showrunner Chris Chibnall on "Broadchurch". She admitted that she had to "tell a lot of lies" after being cast to keep the information secret and used the codeword "Clooney" when talking about the role. She urged fans not to be afraid of her gender, saying ""Doctor Who" represents everything that's exciting about change. The fans have lived through so many changes, and this is only a new, different one, not a fearful one." Chibnall said that he always wanted a woman for the part and that Whittaker was their first choice.
The Doctor (Doctor Who)
Due to time travel, it is possible for the Doctor's various incarnations to encounter and interact with each other, although supposedly prohibited by the First Law of Time (as stated in "The Three Doctors") or permitted only in the "gravest of emergencies" ("The Five Doctors"). In the 1963–1989 television programme, such encounters were seen on three occasions: in "The Three Doctors" (1972), "The Five Doctors" (1983) and "The Two Doctors" (1985). In "Day of the Daleks" (1972), the Third Doctor and Jo Grant very briefly met their future selves due to a glitch during a temporal experiment (the serial was supposed to end with the same scene depicted from the perspective of the "other" Doctor and Jo, but was excised because it was anticlimactic). In "Father's Day" (2005), the Ninth Doctor and Rose observed but did not interact with past versions of themselves; when Rose changed history, the earlier selves – after momentarily noticing Rose running past – vanished and a temporal paradox was created that attracted the extra-dimensional Reapers. The Tenth and Fifth Doctors met in the TARDIS in the mini-episode "Time Crash", which aired on 16 November 2007 as part of the BBC's annual "Children in Need" appeal. This marks the first time the Doctor has met a previous incarnation since the programme's revival. Although the scene aired outside the programme itself, it was established as taking place between the events of "Last of the Time Lords" and "Voyage of the Damned".
