It looks like they're filming in Chicago again for the sequel to Batman Begins. Everything about this movie sounds very cool, just like the first. And now some people have spotted filming going on in the downtown area. I was particularly interested by the following information:

I was talking with someone from the casting office who told me TDK will be in Chicago 'til Sept 2 and then film in London and Hong Kong until Nov.

Night filming in Chicago begins next week where they will film from sundown 'til sunup."

Hmmm...I kind of want to drive around at something like 3 in the morning to see if I can find them shooting some scenes on Lower Wacker :)
