Many actors who have played Superheroes are kinda trapped in the role, they can't advance their career and some just carry on in that role.
Such as Adam West, George Reeves and Christopher Reeve
But what about Michael Keaton? He played Batman in Batman (1989) and Batman Returns (1992), he dropped out of Batman Forever (1995) sadly.
Was he trapped by the role or has he managed to have a good career besides being Batman?
