BAtman will be older but he and Superman will probably be the same age.So we'll be getting an older Batman and Superman with a young Lex Luther. Weird.
I doubt they go with nerdy. I bet they go with a$$hole like he was in the Social Network except multiply the attitude and ego by a billion.They're gonna make him the nerdy "Boy Genius" Lex Luthor who is intimidated by the Man of Steel. It's lazy as fukk and transparent and corny.
