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 11)
The eleventh series of the British science fiction television programme "Doctor Who" premiered on 7 October 2018 and concluded on 9 December 2018. The series is the first to be led by Chris Chibnall as head writer and executive producer, alongside executive producers Matt Strevens and Sam Hoyle, after Steven Moffat and Brian Minchin stepped down after the tenth series. This series is the eleventh to air following the programme's revival in 2005, and is the thirty-seventh season overall. It also marks the beginning of the third production era of the revived series, following Russell T Davies' run from 2005–2010, and Moffat's from 2010–2017. The eleventh series was broadcast on Sundays, a first in the programme's history, after regular episodes of the revived era have previously been broadcast on Saturdays.
