Fan Casting

Despite initially being skeptical, Gene Wilder ultimately fell in love with playing the character, and played The Doctor for 7 whole seasons. But, once the production entered the 80s, Wilder didn't really like the direction it was going, especially with the new hot shot producer that he worked for, for a season. So, he ultimately decided his seventh season would be his last. So a new Doctor needed to be found. The new producer wanted to find someone who was more down to Earth and personable, while also showcasing the manic portrayal of the Doctor when needed. And his choice was Robin Williams. It was very perfect timing as Williams was just finishing his run on another show as an alien: Mork and Mindy. When they approached him for the role, he immediately agreed, being a big fan of the show in his youth. He was a bit skeptical going from one TV show to another, so he approached Jack Lemmon for advice, and Lemmon told him to do the show only for 3 seasons to avoid typecasting. Which is what Williams ultimately decided to do because of this. Now, Robin Williams as the Fifth Doctor begins!
