Apparently, the League of Shadows will be returning, there will be an abundance of studio-shooting, (Rather than shooting on-location like they did with TDK) Anne Hathaway will be playing Catwoman (yuck) and James Newton Howard won't be composing the score.
3rd movie curse strikes again. I'm much more excited for Arkham City than this. I know the movie is a year away, but judging by what we know of the film right now, I don't think I'd even bother seeing this in the theater. Unless some interesting plot detail is revealed, or some new, iconic villain is added to the cast, I might just be getting this from Redbox.
I know it'd be hard to replace Heath, but just because he died, doesn't mean The Joker should die with him. They could find an actor who could do a decent job with the role. It was mentioned on CNN that before Heath's death, he was contracted to star in two Batman films. I think Nolan had a premise in mind for TDKR featuring The Joker, but after Heath died, he scrapped it and instead came up with this potential snoozefest.
