Actors who appear in hit sitcoms often have difficulties shaking off the role that makes their name. Beyond The Joke recently wrote about the way that Father Dougal still casts a shadow over Ardal O'Hanlon's work. But Martin Freeman has had no such issues. I doubt if that many people still think of him primarily as Tim from The Office these days. Even though that was a major role in a landmark series Freeman has recently shaken Tim off with starring parts in The Hobbit movies and BBC1's Sherlock.
