"UPDATE: 6/10/10 10:30 PSTThe Wrap is now reporting that representatives of Joseph Gordon-Levitt have denied the rumor that the actor will appear in the film. We'll be sure to keep you posted if any new information comes forward.
"Chris really dug Joseph [as an actor]," a source close to the director stated. "There was a joke at first between them [on the set of Inception] that Joseph wanted to read for Batman 3 and things heated up as filming continued."
This unnamed source then went on to say:
"It's not 100% confirmed that he's getting [the role of The Riddler] but there's certainly talk about it. Joseph is definitely on the short list."
