When Jesse Eisenberg was cast as the villainous Lex Luthor in Batman Vs. Superman last week, the Internet was flooded with numerous jokes comparing the LexCorp CEO to Facebook founder Mark Zuckerberg, whom the actor portrayed in the Oscar-nominated drama The Social Network. New details have surfaced regarding who this version of Lex Luthor really is, and it seems the Mark Zuckerberg comparisons may not be too far off, but there is still much more to the character than fans may expect.

Be warned, there will be spoilers for Batman Vs. Superman from here on out, so read on at your own risk.

Yesterday, we reported that insiders weren't sure if the actor was going to sport the bald look, but today's report from Latino Review reveals that Lex will not only be bald, but he will also sport an elaborate tattoo of the Metropolis skyline that covers his right arm. The site also gives more details about how Lex became a self-made billionaire at the age of 18, described as "one part tech genius, one part ruthless business man and two parts Metropolis street tough." The street tough aspects are reportedly laid out in a scene where, at the age of 14, when Lex was living on the streets, he was initiated into a street gang, where he learned that there may be people tougher than him, but no one is smarter. A year later, he was running the gang, and he learned that resolve is much more important than strength.

The site also details the first scene featuring Lex, when he takes a meeting at his LexCorp offices with none other than Bruce Wayne (Ben Affleck), while Lex is watching footage of Superman. There is no love lost between the two, with Lex thinking of Bruce as a trust fund baby, while he had to work hard to amass his fortune, and Bruce finding Lex to be an amoral, arrogant brat. Bruce is in town because he is interested in helping to rebuild the city, following the destruction Superman (Henry Cavill) caused in Man of Steel. While Bruce thinks Superman is impressive, Lex thinks he is an alien who doesn't belong on the planet. Still, Bruce wants to put their differences aside and join forces to help rebuild Metropolis. The meeting ends with Lex saying his secretary will send Bruce the contracts, although while he leaves, Lex begins thinking about the mysterious Batman.

Of course, none of this has been confirmed by Warner Bros., but it certainly paints an interesting picture of how Batman Vs. Superman may pan out. Since the destruction of Metropolis is one aspect of Man of Steel that was criticized by many fans, it's interesting to see that they are not just glossing over the efforts to rebuild a major city. It isn't known if these details are from the original script by David S. Goyer, or the new draft being worked on by Chris Terrio (Argo), so it's possible that, even if these details are accurate, they may be reworked in future script drafts.

Zack Snyder is directing, with production expected to begin in Detroit very soon, although it may have started already.
