Looks like a bunch of folks were able to sit in on an editing session with Christopher Nolan as he was wrapping up The Prestige and, subsequently, brought back some more info regarding that Batman sequel, The Dark Knight.
While Nolan is certainly not spilling the beans as far as plot goes, he did chime in on those rumors that had Ryan Phillippe up for the role of Harvey Dent/Two Face and Philip Seymour Hoffman playing the Penguin. When asked about the actors possible participation in the sequel, Nolan laughed and replied, "No truth, no truth to any of those rumors. All interesting ideas though." So, does that mean we're back to square one as far as Dent and Penguin go? Personally, I'd take Nolan's comments with a grain of salt -- I mean, Hollywood often works in mysterious ways.
Nolan also alluded to the fact that there may be a bit more action in The Dark Knight as the film will begin with Bruce Wayne as Batman, making it easier to jump right into the mayhem, rather than spend a ton of time on backstory. The Dark Knight is tentatively scheduled to hit theaters in June of 2008.
