The gossip site that reported the JGL rumor about a month ago is now saying that they spoke to Brody at some event and he said he wants to play the riddler. He says it would be a lot of fun and that he thinks he can do a lot with the character. Atleast this time they gave an event name and the date so it seems like a legitimate reporting as opposed to the "our sources close to Nolan said that."
Still, i think itll be hilarious when its revealed that the villain isnt even the riddler, but somebody nobody expected at all.
Most recently he is the star of Splice and Predators, but in the past he has done such things as The Pianist and The Darjeeling Limited just to name a couple.
