Johnny Depp was recently on a Florida radio show promoting a reunion of his band, The Kids, when an enthusiastic Batman fan called in to remind the host to ask him about this far out rumor of being involved in the next installment of Christopher Nolan's Batman series.
"Oh yeah I heard about that. Not that I know of. It seems like it'd be a fun gig for a while, yeah."
I don't know what that sounds like to you kids, but it sounds like there could be reason to cling on and hope. It's not surprising to get a denial out of Depp as the movie has no script, director, or actors. The studio hasn't even confirmed there will be a sequel yet as Nolan has not agreed to anything. But once Nolan gets signed up, I'd say he might do the world a favor by dropping a dime and talking to one of the world's most versatile and exciting actors. If there's anyo to follow up Ledger's Joker it would be Depp's Riddler.
