Nicolas Cage has said he would be a great Lex Luthor in a Superman movie and he's absolutely goddamn right. Over the course of his career Cage has demonstrated that he's got a beautiful grasp of megalomaniacal self-confidence tinged with craziness that would make him a perfect Luthor. Of course, the role is theoretically currently held by Jesse Eisenberg, but it's unlikely that he's going to reprise the role so who knows?
