The scenes on the street corner with all the prostitutes were filmed the night of the 2000 presidential election. Chicago PD officers in charge of security provided constant updates to the cast and crew as the winner of the election seemed to change on an hourly basis.
Much of the movie was shot in a warehouse on Cermak. Other productions were taking place at the same time, including several adult film shoots. The shoot took place during November in Chicago, and in many indoor scenes, you can see the breath of the actors because it was freezing even inside the building.
A reboot using a cast comprised entirely of sock puppets is in the works.
