Written and Directed by Joe D’Amato.
If there was a script for this movie, I doubt whether anyone involved had actually seen it; the movie doesn’t seem to know in what time period it’s set, and the actors mostly walk around looking slightly confused and talking really, really, really slowly. If you like bad movies, this is the movie for you. Otherwise, stay way. Far away.
(Add two stars if you’re watching the MST3K version.)
