5 actors who asked to die to leave a TV show
In general, TV actors are often disappointed when they realize that their character is supposed to die. Except when they decide to leave by themselves.
Dr. George O'Malley (Grey's Anatomy).
Despite the public's love for its character, T.R. Knight wanted to have him killed and leave "Grey's Anatomy." Because of important "communication problems" between him and Shonda Rhimes, the creator of the show. The latter would have reduced his time on screen in season 5, in comparison with the other main protagonists and the first seasons.
