Every scene in the film was shot in one location - a slaughterhouse that had been shut down. Some of the old slaughterhouse equipment was still housed in some of the rooms, although the building is now being transformed into artist studios for rent.
The physical robot is actually made out of molded ABS plastic. One of the crew members volunteered to wear the highly uncomfortable and very hot contraption for the duration of the scene. It took 2 days to shoot the scene.
