Re: The Joker - What would you do now?
While I don't think anyone could match Heath's Joker I don't think they have to try to. Simple to do "their" Joker. If Nolan requires the Joker for the story of the Third film then I think it's ok to recast. A camo just wouldn't cut it after his powerful presence in TDK.
