“‘No’, says Nolan emphatically and unhesitatingly. He resists elaborating simply because, quite understandably, he says, ‘I just don’t feel comfortable talking about it.’” Christopher Nolan nips talk of recasting the Joker for Batman 3. (There was much fanboy speculation that the Ledger-esque Joseph Gordon-Leavitt, now on Team Nolan as of Inception, might take up the war paint for some kind of Silence of the Lambs-y type nod to the character from the depths of Arkham Asylum. No can do, apparently.)
