There are a few early scenes that are filmed in and around Los Angeles. The scene where Anthony Edwards pretends to pull over Penelope Ann Miller is filmed on Yale Street, in Claremont, CA. Later portions of the film are in the Fairhill and Norris Square neighborhoods which are now known as "The Badlands" circa 2000. Diamond Street is within this area, but Philadelphia police districts are numbered, not named for streets or neighborhoods.
