5. Steve Buscemi
HBOSteve Buscemi is a character actor who has crafted an entire career out of bringing oddballs, weirdos and psychopaths alive on-screen surely there are very few men who would make a more perfect Riddler? He may be a slightly more senior option but if the films director Zack Snyder can craft a plausible premise which would allow for Riddler to be a fifty-something year old man, Buscemi would make an excellent antagonist. In many of Buscemis films he plays a villain who is strangely vulnerable despite ostensibly being the bad guy. His slight, unimposing build means that the actor is rarely cast as someone who is supposed to be physically intimidating. In Fargo he plays a contract killer who is eventually murdered by his own partner in crime with an axe and is unceremoniously disposed of in a woodchipper. In Tarantinos classic Reservoir Dogs, Buscemi may be playing an armed robber but he is still the thug who ends up receiving the Mr Pink alias to the amusement of his fellow villains (Why am I Mr Pink Because youre a f**got). Like the many antagonists already played superbly by Buscemi, Riddler isnt supposed to be perceived as a physical threat. This is why the star of Boardwalk Empire would be so excellent choice to act opposite Afflecks Batman.
