An elderly couple, portrayed by Boris Karloff and Catherine Lacey, experiments with a new device designed to influence people, discovering they can manipulate the actions of a younger man played by Ian Ogilvy. The story unfolds in London and raises questions about the morality of such scientific advancements. Elizabeth Ercy and Victor Henry also appear as friends of the young protagonist. The film, "The Sorcerers" from 1967, might suggest tales of magic set long ago, but it’s actually a science fiction/horror production taking place in contemporary London, produced by a smaller studio competing with Hammer Films. I once read one reviewer criticize its premise as being ridiculous, but that's part of what makes it science _fiction_. Karloff was quite advanced in age at 79 during filming, while Ian Ogilvy is familiar to some from his role as the central character in “Witchfinder General” (1968), also known as “The Conqueror Worm.” The film features a strong female presence with Elizabeth Ercy being particularly striking, alongside Susan George as the protagonist’s former girlfriend and Sally Sheridan as a singer performing at a nightclub. It's an enjoyable way to get a glimpse of London during the mid-1960s. The central character is compelling—more accurately, he’s a victim of circumstance—the female performers are beautiful, the storyline has appeal, the underlying message carries weight, and there’s a fair amount of activity throughout. The movie's length is 1 hour and 26 minutes, and it was filmed entirely in London. GRADE: B-/B
