All scenes in the subway car were filmed in a studio mockup of IRT World's Fair Lo-V #5674. The producers contacted St. Louis Car Co. for original blueprints of the car and painstakingly reproduced it. Lights were mounted along the car exterior and illuminated sequentially to simulate a speed of 30 mph. The NYC Transit Authority refused to grant permission for filming on its property. Subway footage was filmed by concealing the cameras inside bags. Police became suspicious when they heard whirring sounds inside the bags.
