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 8)
Series 8 was initially slated to be broadcast starting in the late summer of 2014, with Steven Moffat acknowledging this likelihood in July 2013, prior to the announcement of Peter Capaldi's casting. In September however it was suggested that the broadcast date would likely be pushed back to the third quarter of 2014, which would tie in with the production starting in January 2014 and typically lasting up to 9 months before the transmission of the first episode. It was also suggested that the series would be a twelve rather than thirteen episode run. In an October 2013 interview, Steven Moffat said that there will be at least 13 episodes in the series.
