Doctor Who
Thirteen actors have headlined the series as the Doctor. The transition from one actor to another is written into the plot of the show with the concept of regeneration into a new incarnation, a plot device in which a Time Lord "transforms" into a new body when the current one is too badly harmed to heal normally. Each actor's portrayal is unique, but all represent stages in the life of the same character. Together, they form a single lifetime with a single narrative. The time-travelling feature of the plot means that different incarnations of the Doctor occasionally meet. The Doctor is currently portrayed by Jodie Whittaker, who took on the role after Peter Capaldi's exit in the 2017 Christmas special "Twice Upon a Time".
Christopher Eccleston
On 2 April 2004, it was announced that Eccleston was to play the ninth incarnation of the Doctor in the revival of the BBC science fiction television series "Doctor Who", which began transmission on 26 March 2005. Eccleston was the first actor to play the role who was born after the series began, albeit by less than three months. On 30 March 2005, the BBC released a statement, ostensibly from Eccleston, saying that he had decided to leave the role after just one series, because he feared becoming typecast. On 4 April 2005, the BBC revealed that Eccleston's "statement" was falsely attributed and released without his consent. The BBC admitted that they had broken an agreement made in January not to disclose publicly that he only intended to do one series. The statement had been made after journalists made queries to the press office.
