When the Super Bowl trailer came out, I remember some people were wondering about the shot of the flying squirrel' guys jumping out of the plane- the shot threw some people off, because the shot was flipped. Watching the end of the most recent trailer, Chicago's geography is all nuts again. Plus, if you watch the building next to the glass one that the 'giant drillbot' is bear-hugging, the style of the building changes. They actually shot the glass building at 155 N Wacker Drive. However, the building in the shot in the film is relocated to the Northeast of the Loop, up in the River East area. The structure has been footprinted in the film to the east of a structure at 160 E Illinois St. I remember on one of the last days they were filming, I saw a camera-copter circling near this area, and was wondering what they were doing. I'm convinced that they were getting some shots for the bit at the end. Also,at frame 2:12, the shot is flipped.This should be an East-to-West view, not vice versa. So...anyone else as crazy as me in analyzing the trailer? I'm still hoping my workplace building will be one of the many in the Chicago landscape with 'battle-damage.'
