Doctor Who: What Happened To Each Doctor After They Left The Show?
10. Jon Pertwee
Last Regular Episode: Planet Of The Spiders
Jon Pertwee stepped down as the Third Doctor in 1974, citing a multitude of issues including the death of his co-star Roger Delgado, as well as his wish to pursue a career on the stage. And that's exactly what he did, starring in The Bedwinner in a London theatre not too long after his time with the show had ended.
He then went on to headline another popular TV show, Worzel Gummidge, and its followup, Worzel Gummidge Down Under. Both were extremely successful programmes in their own small way, and the title character is easily Pertwee's most famous role besides the Third Doctor.
Pertwee also turned in one more performance in the Doctor Who universe, returning for The Five Doctors in 1983. He died in 1996, aged 76.
