Nolan's casting of female roles has been one of the weak points of his first two Batman films. Hopefully he gets it right this time.
I think Maggie Gyllenhal was great in TDK. Not the biggest selling point, but she wasn't bad like Katie Holmes was.
I want Poison Ivy!
Not sure how that would work in Nolan's Batman without completely changing the identity of the character. Ra's and Scarecrow worked because in Ra's case, the Lazarus pits could be taken away easily and still keep a compelling villain, and the Scarecrow was a good way to keep the fear theme in that movie prevalent. Joker and Two Face are also powerless and worked well, and their basic identities established by the comics were unaffected.
The problem with Poison Ivy is that she is defined by her seductiveness and her control over plants. I don't think a seductress is really the best way to keep a villain afloat in a movie where the main character rides around in a tank dressed as a bat. I suppose she would weaponize some kind of love drug to get what she wants, then kills them with poison, but the plant thing is such a big calling card of hers, I'm not sure we would really "recognize" her the way we could recognize the other four big villains. But if she is the villain, I'm sure Nolan could make it work. Lets just hope Tom Hardy isn't Bane
