Curse of the Crimson Altar

Curse of the Crimson Altar is a 1968 British horror film directed by Vernon Sewell and starring Christopher Lee, Boris Karloff, Barbara Steele and Mark Eden. The film was produced by Louis M. Heyward for Tigon British Film Productions. The film was cut and released as The Crimson Cult in the United States. It is based uncredited on the short story The Dreams in the Witch House by H. P. Lovecraft. This film also featured one of the final appearances of horror heavyweight Karloff.

The house used for Craxted Lodge is Grims Dyke, the allegedly haunted former home of William S. Gilbert, located in Redding, Harrow Weald, Middlesex, London. The building, which is now a hotel, was used for both exterior and interior shots.The New York Times said Karloff himself, cadaverous and almost wholly crippled, acts with a quiet lucidity of such great beauty that it is a refreshment merely to hear him speak old claptrap. Nothing else in The Crimson Cult comes close to himthough there is Barbara Steele in greenface playing Lavinia, a glamorous 300yearold and a monumental cast that lists no fewer than sevenparty girls, plus several sacrificial virgins. ........
