Your scoop on the Gotham Times newspaper reminds me: A couple of nights ago, I was biking west down Wacker Drive around midnight, and I noticed a film crew set up on the NW corner of Wacker and LaSalle (might have been Wells) with some extremely bright lights (I assume to simulate dawn or daylight for the shot). They were facing the lovely railing over the river at that corner and had a few barriers set up to direct passers-by just outside of the frame of the picture (there were surprisingly still a number of people out at this hour). I stopped to wait for the light and observed that they were filming an old man (in near close-up) and he looked like a classic 1940's style newspaper vendor wearing a smock that said "Gotham Times" on it. I couldn't quite make out what he was saying, but I caught something about "crazies in costumes" and he sounded pretty angry.
I assumed they were doing a pickup for TDK, but now I wonder if you won't see this video surface soon as part of the marketing campaign for the film. Keep your eyes peeled.
