Heath Ledger and Heroes, who can ask for more??

I know I'm probably late on the pick-up on this story, but I just found out that Heath Ledger will probably be playing the Joker in the next Batman film. I must say that I am surprised at this casting, it's something that I never would have thought of, but it might just work! Good luck Heath, it could be more or a risk than Brokeback was, so consider it carefully!!
