While the Lex Luthor character was rumored to be a part of the Batman v Superman: Dawn of Justice story, no one was expecting Warner Bros. to cast 30-year-old Jesse Eisenberg as the iconic villain back in January.

"I've been in things that have been popular before. To say, I can't do that which will appear in thousands of theaters on opening day, but I can do this which will appear in this amount of theaters... It's arbitrary. I realize how popular comic-book movies are, and now, working on one, I realize why they're popular - the story is really good, the dialogue is really good, the artistry behind every department is high, the acting is really good.
