Gato Chico put together this poster, the first time I recall someone wanting Casey Affleck to play the Riddler.
Just the one piece of news today. Batman on Film is reporting that even though Warner Brothers fully expects Christopher Nolan to direct the next Batman movie after he finishes Inception, should that somehow fall through, their backup plan will be Watchmen/300 director Zack Snyder. I'll reserve judgement on Watchmen until I've seen it, but I worry it will end up like 300. Very slick looking, great trailer, great attention to detail, but in the end not all that good. Other than Nolan being my first choice, I'm not sure who I'd prefer... David Fincher comes to mind, but I recall hearing that he has no interest in superhero movies. Martin Campbell maybe? Though other than Casino Royale, he hasn't done all that much that I've liked. Feel free to leave any thoughts in the comments.
After The Scarecrow, Ra's Al Ghul, The Joker, and Two-Face, who should be Batman's next enemy in the Batman Begins/The Dark Knight series? Well, as of now we know that Tom Hardy will play Bane and Anne Hathaway will play Catwoman.
Check out the master list for all the villains covered. I've pretty much run out by now. Obviously, there are more Batman villains, but not any of significance that I know of. As of February 2009, no one is confirmed as a villain. Not the Johnny Depp Riddler, not Phillip Seymour Hoffman Penguin, nobody.
