‘The high priestess of evil… a monstrous demon with an irresistible bloodlust…’
Curse of the Crimson Altar is a 1968 British horror feature film directed by Vernon Sewell (ghost ship; The Terror of the Blood Beast; burke and hare).


The film was produced by Louis M. Heyward for Tony Tenser’s Tigon British Film Productions. It is based (uncredited) on the short story “The Dreams in the Witch House” by HP Lovecraft.

The film stars Christopher Lee, Boris Karloff, Barbara Steele, Virginia Wetherell, Michael Gough and Mark Eden.



On July 7, 2015, Kino Lorber released the film on Blu-ray in the United States with an audio commentary by David Del Valle and Barbara Steele, a conversation with Christopher Lee, an interview with composer Kendall Schmidt, American trailers and British.

Robert Manning (Mark Eden) goes in search of his brother, who was last known to have visited the isolated home of Craxted Lodge in Greymarsh. Arriving at night, he discovers that a party is in progress and he is invited to stay by Eve (Virginia Wetherell), the niece of the owner of the house.

His sleep is restless and strange dreams of ritual sacrifices disturb him. Inquiring about his brother, he is assured by the owner of the Morley house (Christopher Lee) that the man is not there. But Manning’s suspicions are still aroused by his nightmarish hallucinations.

When occult expert Professor Marshe (Boris Karloff) informs Manning of a witchcraft cult based around the ancestral Lavinia Morley (Barbara Steele), the cult is uncovered…

“Karloff himself, cadaverous and almost entirely paralyzed, acts with a quiet lucidity of such great beauty that it is refreshing to simply hear him talk old spiel. Nothing else in The Crimson Cult comes close, though there’s Barbara Steele in greenface playing Lavinia, 300-year-old glamor and a monumental cast that lists no less than seven party girls, plus several sacrificial virgins.

“Lovecraft’s story is ultimately much more disturbing than this adaptation, which features very little on-screen violence, although Wetherell shows exactly one of her breasts and her entire bare ass, which were probably outrageous in their day. “Oh, the Horror!

“The novelty of this latest Karloff film is not enough to save the company, though the film, posthumously, retains miniscule interest as a curiosity of its time (yesterday’s trash is more tolerable than today’s trash.) Villagers celebrating Independence Day, villagers playing hide and seek, attempted human sacrifice and self-immolation are inexplicable ingredients in this woefully underdeveloped brew.
