18 Actors You Totally Forgot Were In Marvel Movies

6. Eric Dane - X-Men: The Last Stand

Some people will have you believe that X-Men: The Last Stand is the worst X-Men movie ever released. Those people have clearly never seen X-Men: Origins.

The problems with The Last Stand are well documented - and most come down to the fact that Bryan Singer bailed to make Superman and left his project in the wrong hands - but it's still a lot of fun. It also has some great mutant moments for fans of the comics, including the debut of some otherwise overlooked characters.

That includes the first real appearance of Multiple Man, who was played by Grey's Anatomy star Eric Dane, the same year his career-defining role on the show debuted.
