It is a movie I watched twenty years ago on VHS when I was a child. I’m sure this movie is from 1985-1998. It looks like a movie in which a woman with short hair worships a demon. I “think” that this demon has a name similar to “Odin”, but I’m not sure. She appears to have a snake-like power, with its teeth growing when she attacks. I remember two scenes: she sees a religious painting on the wall and spits corrosive acid on it making a snake’s noise. In another scene, she receives a young boy, seduces him and when she is going to have oral sex, she eats his penis (not a graphic), injecting something that makes the boy’s body immobile with him alive. She ends up killing the boy by dipping him in her bathtub. Thanks anyway.
The Lair of the White Worm (1988), Ken Russell’s lurid adaptation of a horror novel by Bram Stoker.
An archeologist, working a dig at a bed and breakfast (once the site of a convent), unearths the skull of a large snake. He believes it may be related to a local legend of a giant worm slain centuries earlier by the Lord of the Manor. The archeologist somehow connects the skull, and various disappearances, to a Lady who lives in the area. Lady Sylvia, is in fact an immortal priestess of an ancient snake god, Dionin.
