When this film was released theatrically in Australia, it included a William Castle-like "Fright Break", a short intermission which gave audiences a chance to walk a yellow line to the cinema's exit if the film was too frightening for them, giving those who took the so-called "Chicken Walk" to the exits their money back. The "Fright Break" sequence is included on the Australian video release.
This film is considered an "Ozploitation" (Australian exploitation) picture.
