The film was shot during the course of a single weekend, with an additional day of pick-up shooting 3 months later.
The second half of the movie was originally scripted to take place inside a college library. The library to be used was accidentally flooded during another film shoot and the script had to be rewritten.
On most of Joseph Wilka's films he acts as director, writer, producer, cinematographer, and editor. This is his first where he is credited only as the film's writer/director.
During the big crowd scene, a special fog machine was used to create the rising smoke from a crashed alien ship. Loyola Marymount University's Campus Security received a call that the bluff was on fire and had to be convinced by the film's producer that all was well.
Andrew Freire had to spend nearly 5 hours in the make-up chair for the alien creature effects to be applied.
