An underrated slice of late Sixties horror/psychedelia. It was filmed in 1968 and reminded me somewhat of The Dunwich Horror which was made around the same time and similarly attempted to update Lovecraft with setpieces inspired by the drug culture and the Summer of Love. The difference with the Crimson Cult is that it was filmed in England with a stellar cast who can actually act, unlike poor fish-out-of-water Miss Sandra Dee in Dunwich. It is a treat to see Boris Karloff and Christopher Lee trading pleasantries in their scenes. Michael Gough extracts the maximum from his small role as a pitifully unhinged factotum. Barbara Steele exudes a grandly Gothic malevolence in her scenes as Lavinia. She is probably the single most memorable presence in the film and whatever power it possesses is largely thanks to her. (Great costume, too!) The dungeon sequences are probably the best though my favorite moment in the film occurs when the innocent young man asks Karloff's sinister professor "What do you collect?" and with a friendly grin Karloff replies, "Instruments of torture!" Marvelous moment.
This movie is ridiculously difficult to find. After years of searching I located a bootlegged videotape which is in terrible condition--grainy and the colors which should be vividly over-the-top are quite washed out. Also the print lacks the original score which was quite nifty as I recall from seeing it on American television in the early 70s. There is supposed to be a laser disc version from the early 90s. It would be great if a patron who owns this would do a review of that.
