We know two hard facts about Jesse Eisenbergs hairstyles in Batman V Superman: Dawn Of Justice. For one, weve seen that floppy dirty brown barnet countless times throughout the trailers. In official pictures released to the press (see above), weve also seen Jesse Eisenberg sporting a traditional Lex Luthor bald-headed look. A lot of people are assuming that Lex being quite young will go bald over the course of the film, perhaps as a result of all these weird experiments hes been dabbling in. However, showing how minute a detail can inspire fan theories these days, some fans have been quick to speculate that Lex is wearing a wig from the start. According to this theory, Eisenbergs villain went bald ages ago, and is now trying to hide it with a trendy wig. This, presumably, would be a metaphor for the supervillain persona that Lex is attempting to hide beneath the veneer of being a young entrepreneurial whizz-kid. Of course, if this theory turns out to be true, Lexs wig could also become a comic relief feature in the film. Like Gene Hackman before him, we could see Jesse Eisenberg flapping around attempting to keep his hairpiece in place while chaotic situations unfold around him. Post-Man Of Steel, the DC movies could do with a few comedic beats, so this wouldn't be entirely unwelcome.
