This efficient and highly enjoyable Hammer film showed both the economic brilliance of Britain’s most successful independent production company and their willingness to experiment. The film was shot back to back at Bray studios with The Reptile (1966). Both films employed the same director John Gilling, the same technical personnel, and the same Cornish setting. The themes of both films intersect in interesting ways, and it is helpful to view both films as flip sides of the same coin. The setting is integral to both films, but probably more so to The Plague of the Zombies. The writer Peter Bryan is able to make the class dichotomy even more keener in a rural village riddled with resentment and superstition. And the insertion of a foreign menace in the shape of Haitian voodoo in an already polarised village aids the simmering tensions that Sir James Forbes (Andre Morell) and his daughter Sylvia (Diane Clare) encounter when they arrive to assist the local GP in uncovering the cause of an inexplicable outbreak of plague.
