The film was shot outside of Los Angeles and while the cast was provided hotel lodging, the director, producers and the crew camped out on the floor of the shooting location for all the days of the shoot.
The security vehicle seen at the beginning of the movie is actually the producer's SUV with two electric strobe lights clipped to the roof bars. The strobe lights were covered with red gel to simulate a security vehicle look, and electricity was provided by a power inverter plugged into the cigarette lighter.
