The film was shot in 'Joseph Greco''s hometown. A hurricane nearly shut the Florida production down.
Joseph Greco: The scene at 41:55 of the South Florida State Hospital as Chris sees it through a chain link fence is a cameo of sorts - the director is one of the "workers" walking past the building, "not because I wanted to, but because we had no one else and I needed someone in the background, walking, to liven up the shot."
