Edward Norton has said no to anymore 'Hulk' movies as he "wanted more diversity" with his career, and that he didn't want to be associated with just one iconic character.
According to the Hollywood Reporter, Norton has admitted that he enjoyed playing the character, but he has experienced what he had.
He said that he thought that if one does something too many times, it could become a suit that's hard to take off, in other peoples' eyes.
Mark Ruffalo has taken over the role since then.
