Thats cool. I didnt know they film a lot up there. They just filmed a full bus crash for the graphic novel adaptation of Wanted right outside my work. It was done on Wabash and Wacker. It was pretty cool stuff.
They actually filmed some of the movie Wanted at my hotel on our roof. It was the easiest day of work for me ever. i got to sit around and watch all the film equipment all day. Piece of cake. There is a small chance they may do some shots for Batman up there too. So Fingers crossed.
from his look here, and his sound from the teaser trailer, i think he's going to do well as the Joker. Whether he's better than Nicholson is to be seen, but this Joker is one creepy lookin dude. I'm excited
