According to sources, "The Dark Knight" is now doing "pre-production filming" in Chicago. The production will spend six days in the Windy City before jetting over to London to do almost all of the movie. Those pics you saw last week (the blurry ones of Heath Ledger as The Joker) were from Chi-town, which is where part of a bank robbery sequence is being shot.
Regarding cast, fans of character actor William Fichtner will be happy to know that he’s been cast as a bank manager. (If you don’t recognize the name, I bet you know the guy from movies like "Armageddon," "Go," "Ultraviolet," and "Blades of Glory.") Also, Joker’s gang will be portrayed by actors Michael Stoyanov, William Smiley, and Matthew O’Neil.
