No, there will be no replacement for the Joker in the Nolan reboot series. And anyway, as Michael Caine said, "who could follow that? Who would WANT to follow that?" As for the villain in the next one... I'm pretty sure Two-Face is dead (btw I thought his second face was absolutely horrifying and believable, except for the fact that his left eye was still working which is the only sketchy thing in the whole movie) because they had a funeral for him and stuff. Personally I'm hoping the Nolan brothers put their heads together and write a new villain. These films are absolutely on par with the best of the comics, and if someone can introduce a character in the 60s (20 years after Batman was first published), why not here and now? I mean, Chris Nolan's made, what, 5 films? And they've all been absolutely spectacular? At least half of his entire career is on the IMDB top 250. Batman is in good hands. I preferred Maggie Gyllenhaal to Katie Holmes by a longshot. Chrsitian Bale was awesome as usual, though his spotlight was of course stolen. I hear Bale is starting a death metal band? Even Gary Oldman, whose character simply had nothing wrong with him (no tragic loneliness, no madness or sadism) stood up to the theatrics of Ledger, Eckhart (who was also amazing) and Bale's characters with the subtlety of a master. Ledger's performance was perfect. It doesn't hurt that he was also one of the best written villains of all time, but plenty of the lines ("Madness is like gravity, all it takes is one push") were improvised on set. The question is, will he be nominated for Best Actor, or Best Supporting Actor?
