Curse of the Crimson Altar (1968)
a.k.a. The Crimson Cult
Director: Vernon Sewell
Antiques dealer Robert Manning (Mark Eden) visits a remote country manor in search of his missing brother, and soon finds himself entangled in sinister occult doings. Very loosely inspired by H.P. Lovecraft's short story "The Dreams in the Witch House."
- The last film to feature Boris Karloff which was released during his lifetime.
