23 TV Characters Recast After The Actor Quit the Show
Mason Verger (Hannibal)
Every character on Hannibal is twisted in one way or another. In the case of Mason Verger, his internal demons become external eventually. The character was actually played by two different actors over the course of the show. On season two, Michael Pitt stepped away allowing Joe Anderson to step in.
Michael simply decided not to return to the part, but his decision came at a good time. When he last played Mason, his face had just been deformed. This meant that Joe could take the role without much trouble. The switch from one actor to another was hardly even noticeable.
