Career: Baker started appearing in obscure plays in regional theatre, working in pubs to make ends meet. He made his film debut in 1968's A Winter's Tale and appeared on TV in dramas such as Dixon of Dock Green. A year later he joined Laurence Olivier's National Theatre, but left in 1971 to star as Rasputin in Nicholas and Alexandra. Baker also appeared in The Canterbury Tales and The Golden Voyage of Sinbad. By 1974 roles had dried up and he was working on a building site when he was offered the role of Doctor Who. He went on to become the longest-running Time Lord, quitting in 1981 after seven years. Since then, he's worked on stage, TV and in film, most notably in Medics, and the remake of Randall and Hopkirk (Deceased). He published an autobiography in 1997 and is constantly in demand for voiceover work.
