This is Jesse Eisenberg as Lex Luthor
Jesse Eisenberg’s is set to take on the founding members of the Justice League as Lex Luthor in Batman v. Superman: Dawn of Justice. He certainly looks menacing enough in this first photo from Entertainment Weekly, as he’s already a far cry from Gene Hackman and Kevin Spacey’s take on the classic character. He might not be the actor you’d expect, but Snyder clearly trusts his abilities. “Our Lex is disarming and he’s not fake,” he told EW. “He says what he believes and he says what’s on his mind.” Expect to see more of this face in the run up to the film’s premiere on March 26th, 2016.
