Why Every Lead Actor Left Doctor Who
7. Sylvester McCoy
Unlike most of his fellow Time Lords, Sylvester McCoy never technically "left" Doctor Who, nor was he fired. He was simply unlucky enough to be the Doctor in 1989, the year in which production of the show was suspended.
It's a shame too, because McCoy had settled into a solid groove towards the end of his era, with he and Sophie Aldred proving a winning combination. Unfortunately, public perception of Doctor Who was at an all-time low, and with viewership declining, the plug was pulled.
Regardless, McCoy was still the incumbent Doctor for the 1993 charity special Dimensions in Time, and the start of the 1996 TV movie. Writer Matthew Jacobs wished to link the movie directly to the classic series, and so it was decided to depict the Seventh Doctor's regeneration.
