English suspense film with a very solid British cast, along with lone American Paulette Goddard. Sylvester, Maben, and Napier are all quite good, but it's Goddard who doesn't quite fill her characters larger than life shoes. She plays Angie, a woman all the men in the film seem to love and adore, as well as Maben's Joan, who is completely devoted to Angie. Goddard is fine but is unable to create a character of great wit, dynamism, beauty, or uniqueness to make such admiration from everyone even remotely plausible. This unfortunately undercuts large parts of the story. The direction is also a bit pedestrian and lacks vision. Despite the many flaws and weaknesses, The Unholy Four is not without suspense was still mildly entertaining.
