This movie was filmed between 1989-1991 as a micro-budget indie, then spent the next 7 years seeking completion funds. Finally finished in 2000, it was released as a rental title by Spartan Home Entertainment, then picked up a year later as a sell-through title by Fox, who proceeded to botch the manufacturing and mistakenly only release the full screen version with bad sound and no extras.
According to the display screen on the security computer when the motion detectors go off, the film takes place on 14 September 1989.
