The Crimson Cult (Curse of the Crimson Altar)

When his brother disappears, Robert Manning (Mark Eden) pays a visit to the remote country house he was last heard from. While his host Squire Morley (Christopher Lee, The Oblong Box) is welcoming, Manning detects a feeling of menace in the air with the legend of Lavinia (Barbara Steele, Black Sunday), the Black Witch of Greymarsh, hanging over everything. Will the village's renowned expert on witchcraft, Professor John Marsh (Boris Karloff, Black Sabbath), be able to shed light on the wicked goings on at The Craxted Lodge? Vernon Sewell (Ghost Ship) directs this nightmarish horror classic based on H.P. Lovecraft's 'Dream in the Witch House'.
