The police station was filmed at Union Station in downtown Los Angeles. Ridley liked it because of the art deco and neo-Fascist architecture and because of its immensity. We built Bryant's office at the station, but made one giant mistake. We built it around the access to the ladies' bathroom so that every time we started shooting, some little old lady would want to use the bathrroom.
