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)
In "Journey's End", the Tenth Doctor manages to avert his own regeneration by using some of the energy to heal himself, then channeling the remaining energy into his severed hand, thus retaining his appearance and personality. That regenerative energy was a key point in a "human–Time Lord biological metacrisis" inadvertently caused by Donna Noble that creates the Meta-Crisis Doctor while she obtains a Time Lord intellect. Later in the series, during the events of "The Time of the Doctor" the Eleventh Doctor revealed that it was considered a full regeneration; he just kept the same face due to "vanity issues", and that he was now in his final (13th) life (given that the Tenth Doctor counted as two regenerations and the revelation of the existence of the War Doctor, this made a total of 12 regenerations). However, during the same episode, the Doctor is given a new cycle of regenerations by the Time Lords, allowing him to regenerate for the thirteenth time into the Twelfth Doctor, with the Twelfth Doctor ("Kill the Moon") and Rassilon ("Hell Bent") each expressing uncertainty about how many regenerations the Doctor now has.
