5. Joel Edgerton
Ill hold my hands up and say right now that theres only one film in which I can remember Edgertons performance and thats 2011s Warrior, which he starred in opposite Tom Hardy, whos perhaps now most synonymously remembered as Bane in The Dark Knight Rises. But, considering Id never really heard of the guy previously, his fantastic performance caught me by surprise, blowing my mind in the process. Its fair to say that Edgerton still has a relatively low profile compared to some of the others in this list, but maybe thats exactly what the character needs, especially if hes going to share the screen with a whole host of other performers. And thats what theyve done with Superman, right? Christopher Reeve was relatively unknown when he took the role in the original Richard Donner movies, Brandon Routh was an unknown before Superman Returns, and even Cavill, our newest Man of Steel has only a few decently profiled roles under his belt. So for the next Batman casting, why not try out a lesser known performer? You never know, he might just blow all of our minds.
