It's becoming increasingly apparent that, while it's the titular showdown, Batman V Superman: Dawn Of Justice is more than just Ben Affleck owning Henry Cavill for two-and-a-bit hours. The subtitle hints at ample Justice League set-up, after all, and, as more and more information comes out about the movie's plot (when you consider it, we know very little about how it'll go down) it's becoming clear the big finale will see World's Finest unite against a bigger foe. The exact nature of that threat is up for speculation, but one thing is clear - it's all the masterwork of Lex Luthor. Jesse Eisenberg's Luthor has been the source of much controversy, rivalling Ben Affleck's casting as the Caped Crusader in terms of fan backlash (and unlike Batfleck DC fans haven't really warmed to him). There's so many facets of the actor's supposed unsuitability, but the short of it is that he's too young, cast primarily because of his work in The Social Network, indicating a nerd Lex. And that's without even get started on the hair. We already know he's very different to the classic iteration of Luthor - that's an intrinsic element of the casting anyway, but an ARG Fortune profile further revealed he was actually Alexander Luthor Jr., his father having died years previously. Aside from opening up the potential for some form of prequel with a more classical version of the character, it reaffirms that Eisenberg's take is a Luthor for the 21st century. But let's go a little further than that. While Lex is already seemingly very different here (although that odd hair will eventually make way for a nice bald dome), could DC be looking for something even more radical than we currently expect? What if, instead of going the typical mech suit route (something we'll have already seen with Batman), they find a way for him to tackle Superman physically. What if making him Jr. is a way to make him even more a direct opposite to Superman. What if Jesse Eisenberg's Lex Luthor is actually Kryptonian. Wait, Lex Luthor a super-powered being from Superman's home planet? Sounds crazy, right? Well, it kinda is, but when you take a look at what Warner Bros. have tried to do with the character over the past couple of decades and their general approach to the DC Extended Universe it's a twist that actually makes some sense...
