Along with a new (and possibly older) Batman, Superman antagonist Lex Luthor is all but a lock for the upcoming Man of Steel sequel (or, if you prefer, Batman vs. Superman). The character was teased multiple times in Zack Synder's Superman reboot - as the LexCorp logo appeared on the side of trucks and was featured on several pieces of Metropolis construction site signage - indicating that, even though General Zod was the main focus in round one, Luthor was already hard at work building an empire in this new Superman universe.
Since the character did not actually appear in Man of Steel, the rumor mill is hard at work churning out possible names that could be in consideration for the part - Mark Strong (Green Lantern) and Bryan Cranston (Breaking Bad) being the most recent actors that have been name dropped as possibilities. However, being up for a role (assuming the rumors are true), is very different from actually being cast. Is it possible that one of the two could eventually get the part? Yes. Is it a guarantee at this point? No.
As a result, we've put together a list of 5 actors (not including Strong and Cranston) that would make for an interesting Lex Luthor in Batman vs. Superman. Of course the list is not all-inclusive, so once you've had a chance to read our picks, share your ideas in the comments.
