This movie is often confused with Jesús Franco's similar movie from the same year, White Cannibal Queen (1980).
The film was briefly available in the UK as a pre-cert (and now very rare) video before being banned and placed on the DPP list of official video nasties. It was finally passed fully uncut in 2008.
The demon's bug-eyes were created with ping-pong balls that had tiny holes poked in them to allow the actor to see.
No sets were built for this film.
