Ben Affleck

He's such a great director, and a solid actor as well. Guy just makes bad choices. Daredevil was one of those. Ben not only didn't look the part of Matt Murdock, he was also backed by an awful script and a supporting cast that, for the most part, did him no favors. It's sad that his first opportunity got screwed up as hard as this one did.
Affleck certainly looks the part as Batman, and I don't mind his bat-voice. Plus, he captures the air of an older Bruce Wayne very well.

SPECIAL BONUS: While this one doesn't really count, Ben sorta got to play Superman in a good movie that came out a long time ago! 2006's Hollywoodland was about the real unsolved death of 50's Superman actor George Reeves. Affleck played Reeves, and we got a couple scenes of him in the suit that make him look damn good.
