The following is a "spoiler-free" report of TDK shoot in Chicago on June 24, 2007 from "Weird Chicago Adam."
"The Batsignal was in full use last night on the Chicago rooftop. To my disappointment, it wasn't bright enough to actually send a signal into the sky.
Chrisitan Bale was also present on the roof, in costume (with and without the mask - his eyes were painted black, making it look like he was wearing shades), occasionally stepping off to the side to use a cell phone, which he appeared to keep in the utility belt!
Security was in full force around the area - and seemed even tighter -- until you got really close to see that about half of the cops milling about were actually extras in Gotham City police uniforms.
There was a prop table set up which included a lot of small notebooks and microphones labeled ‘Gotham News’ and ‘GTV.’"
