Caine tells MTV that he asked a Warner Bros. executive,
“How the hell are we going to top Heath?”
He was told,
“I’ll tell you how you top Heath — Johnny Depp as The Riddler and Philip Seymour Hoffman as The Penguin.”
I don’t know if it’s possible to top Heath Ledger as Joker, but that combination certainly at least gives you a shot Except I don’t really see this as any sort of casting confirmation. The unnamed WB exec never actually said they had them or were even pursuing them, it sounds more like he was simply spouting off about one of the potential ideas they’re bandying around. If WB’s executives are smart though, they’ll stop dreaming up casting combinations and sit on their hands until Nolan decides what he wants to do. Once Nolan decides he wants to do it, they should continue sitting on their hands and let him do whatever the hell he wants.
