This doesn't come to much of a surprise, but apparently Zack Snyder is giving his Lex Luthor long hair in Batman Vs. Superman.
It's been said LexCorps scenes were filmed recently with Jesse Eisenberge sporting longer hair for Lex Luthor.
It's also said that Eisenberg's hair was dirty-blond loose and wavy.
Batman-News says the LexCorps scenes were taking place early in Batman Vs. Superman; so there is always a chance Eisenberg could loose his locks and go bald. It's also said Eisenberg's Luthor is kind of hyper - "like a 20-something guy that pounds energy drinks all day."
LexCorps has previously been compared to a company similar to Google.
Update: We also get the following from IMDb:
Lex has a super modern-hip Facebook/Google style office with a basketball court, pinball tables, etc. Everyone looks ultra douchey and has bowties and blazers, etc. Lex is introduced in which he takes a basketball shot, and in the same motion, after draining the shot, turns around and shakes a senator's (?) hand, who is there to greet him. He looks like Kurt Cobain, and is a complete douche.
Update #2: Holly Hunter is said to be playing the Senator.
"Batman v Superman: Dawn of Justice" has a newly announced May 6, 2016 release starring Ben Affleck as Batman, Henry Cavill as Superman, Gal Gadot as Wonder Woman, Amy Adams as Lois Lane, Laurence Fishburne as Perry White, Diane Lane as Martha Kent, Jeremy Irons as Alfred, Jesse Eisenberg as Lex Luthor, Ray Fisher as Cyborg with Callan Mulvey, Holly Hunter and Tao Okamoto in new character roles for the film.
