Scooper ‘Ilk’ wrote in about the production taking place for The Dark Knight in Chicago:
More action at the old Chicago Post Office over the past couple days.
Monday afternoon, there were a whole bunch of flatbed trucks out on the loading dock. A crew was hauling in a “Gotham Police Department” sign off one of the trucks. The style of the sign exactly matched the signs the Chicago Police use on their stations… kinda similar to how the “Gotham” license plates are an exact knockoff of Illinois plates.
Today (Tuesday) crews were putting the “Gotham National Bank” signs back up on the north entrance of the post office building. I wonder if these are for reshoots or additional scenes. There were several large lighting trucks parked out back as well.
