Curse of the Crimson Altar (The Crimson Cult here in the USA) has a good cast, but it is not a good film. This is evident from the opening scene.
Not even the terrific pairing of Boris Karloff and Peter Lorre can save this mess.
Fair warning, I’m going to spoil the entire plot of British Intelligence. How else to review it? Plot is all it offers.
Even the most ardent Boris Karloff fan can skip The Ghoul.
