Watch the movie until the past where Keanu Reeves and the girl agree to meet with the professor. Next scene, Reeves and the girl are walking into a museum. If you've ever been in Chicago, you can recognize this as the Field Museum - large dinosaur skeletons within the large lobby area. This is further confirmed when Reeves and the professor meet - they're within the caveman exhibit of the Field Museum, near the balcony overlooking the lobby. The professor reveals they're surrounded by thugs; Keanu and the girl run down a hallway, chased closely by the thugs. The next scenes -- occurring immediately afterward, as they're being chased by the sae thugs -- show Keanu climbing over a Jetplane Exhibit in order to escape the thugs. The Jetplane exhibit, however, is within the Museum of Science and Industry -- miles away from the Field Museum! Somehow, the chase scene has jumped from one major Chicago museum to another in a matter of seconds.
