Becoming typecast is a huge concern for an actor. Unless you have the mesmeric versatility of, say, Phillip Seymour Hoffman, William H Macy or Danny Dyer, the fear of being landed in the same role over and over again is a constant threat.

Here, we examine the most unfortunate victims of this lazy cinematic prejudice.
