Wouldn't it be nice to see Heath Ledger return as the Joker in the 3rd installment of Batman? I was checking out Amazon.com and they have a spot for Customer Discussions and one of the topics was the Return Of The Joker. A comment was made by someone who said that Chris Nolan has scenes from The Dark Knight that never made it into the film, and this includes unseen footage of Heath Ledger as the Joker. He goes on to say that this footage "may" be used in the 3rd movie to help tie up any loose ends.
As we all know, the Joker didn't die in The Dark Knight, and I can't see anyone else taking over the role that Heath has made famous. It just wouldn't be the same. So, if these rumours hold true, and Chris Nolan does indeed have unused footage of Heath Ledger from The Dark Knight that he might use in the next film, how great would THAT be? I say, bring it on!
