Again and again in the seventies when a movie had success some countries were trying to make rip offs, remember the Italian Alien rip off, remember Beyond The Door and remember this flick. But I think you won't be able to remember it because it is an OOP. Never released on DVD. Although it has a following due the reason that it is directed by Amando De Ossorio. Is it a good movie? I just don't know what to think about it, why, the scene's were the possession takes place are rougher in language and performance than the Exorcist but the effects are extremely cheap. I was never frightened, okay it's more then 30 years old but some horror flicks are older and still delivers me the creeps. Anyway, the woman who dubbed Linda Blair in the Spanish version plays the lead here (Marian Salgado). Some actors are believable some are laughable, watch the witch been shot at the end, the way she falls, my god! Anyway, because it's an OOP it's worth watching. Try to catch it, good luck.
