Curse of the Crimson Altar (1968)

Description

Robert Manning (Mark Eden) searches for his brother, who was last known to have visited the remote house of Craxted Lodge at Greymarsh. Arriving at night, he finds 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 sacrifice disturb him. Enquiring about his brother, he is assured by the house owner, Morley (Christopher Lee), that the man is not there. Manning’s suspicions are aroused by nightmarish hallucinations. Occult expert Professor Marshe (Boris Karloff) informs Manning about a witchcraft cult led by Morley's ancestor, Lavinia (Barbara Steele). The cult is discovered to still be active. Craxted Lodge is burned to the ground, and the head of the cult is consumed in the flames.
