In the shot where the Remorath ship is heading towards the downtown area, the view of Chicago is backwards and the ship is heading south. In the next scene, where the ship crash-lands on top of some Chicago office buildings, the view of the city is correct, but the ship is now heading north. Buildings like the Willis Tower and AON Center are on both sides of the former John Hancock Center between the two shots.
While the scenes between Daisy and Talbot are supposed to take place in Chicago, there are light pole banners that advertise exhibits of the Museum of Contemporary Art (MOCA) in Los Angeles, California. There is a Museum of Contemporary Art in Chicago, but its initialism is "MCA".
