The Doctor (Doctor Who)
The Doctor is the title character in the long-running BBC science fiction television programme "Doctor Who". Since the show's inception in 1963, the character has been portrayed by thirteen lead actors. In the programme, "the Doctor" is the alias assumed by a centuries-old alien—a Time Lord from the planet Gallifrey—who travels through space and time in the TARDIS, frequently with companions. The transition to each succeeding actor is explained within the show's narrative through the plot device of "regeneration", a biological function of the Time Lord race that allows a change of cellular structure and appearance with recovery following a potentially fatal injury.
Doctor Who (series 12)
The twelfth series of the British science fiction television programme "Doctor Who" is set to premiere in early 2020, with filming for the series having commenced in January 2019. The series will be the second to be led by Chris Chibnall as head writer and executive producer. This series will be the twelfth to air following the programme's revival in 2005, and will be the thirty-eighth season overall. The series was preceded by a New Year's Day special episode, instead of the traditional annual Christmas Day special.
