Jon Pertwee was the third actor to play the titular good-natured Time Lord on the long-running British sci-fi series Doctor Who, and this video pays tribute to his four-year run in the role. Doctor Who: The Pertwee Years features three classic episodes from the show in which Pertwee starred -- "Frontier in Space," "The Daemons," and "Inferno" -- as well as an interview with Pertwee, a look at the BBC's special effects department, outtakes, rarely seen moments from the series, and a visit to a Doctor Who fan convention. ~ Mark Deming, Rovi
