This movie was actually based on the Heaven's Gate cult that up and committed mass suicide in San Diego in 1997. The characters played by Pointer and Forsythe are based on Ti and Do, leaders of the UFO cult. Although the movie is profoundly hokey, it's a pretty chilling thing to watch when you realize that it's based on a genuine cult and sort of illustrates exactly what their plans were 15 years before they decided to act on them.
