Was partially shot at the mansion from "Burial Ground: The Nights of Terror (1980)".
Mariangela Giordano regretted filming the scene in which she is violated by a floating poker: "This movie is the worst instance of how shocked I was in retrospect by something I'd done on film. That poker scene is so disgusting, so terrible, only Gabriele[Crisanti] could have sweet talked me into actually doing it!". "It took two days to film that scene, and because the poker had to keep thrusting between my legs before it came out of the top of my head, it got more and more painful as we kept going. And it was cold and freezing. I don't know why Gabriele always insisted on making these movies during winter."
Mariangela Giordano was the real life girlfriend of Gabriele Crisanti, who was the producer of this movie and of Giallo in Venice (1979). In both these movies, Giordano's characters suffer grim and gory comeuppances. "Looking back I shouldn't have done them. But I was in love with Gabriele. I would have done anything for him. Now I can see how the increasingly gruesome ways he had me killed in them was a reflection of the breakdown in our own relationship," Giordano said.
The Movie is a low-budget unauthorized sequel of the Australian horror Patrick (1978) from two years earlier.
