5. Aaron Paul
Aaron Pauls previous major role, as Jesse Pinkman in Breaking Bad, will probably be about the furthest you could ever imagine from The Joker, especially in the earlier series'. Throughout the show though, Paul has let a sort of destructive confidence flow through Jesse and combined with his uniquely Jokerish facial structure, piercing blue eyes and ability to convincingly look like hes about to lose his marbles, Id say hed be as fine a Joker casting choice as anyone else. Of course, if you know Paul youll probably be used to the Hey, Yo Mr. White, lets bounce attitude of his character in Breaking Bad, but forget that and remember: hes an actor. If Nolan had looked no further than Ledgers performance in A Knights Tale, we may never have gotten the interpretation of the Joker that we did. Maybe it's time for a different angle on the Joker?
