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".
Doctor Who
In 2011, David Yates announced that he had started work with the BBC on a "Doctor Who" film, a project that would take three or more years to complete. Yates indicated that the film would take a different approach to "Doctor Who", although the current "Doctor Who" showrunner Steven Moffat stated later that any such film would not be a reboot of the series and a film should be made by the BBC team and star the current TV Doctor.
