Though highly derivative of the 1942 Cat People, this British movie is quite dramatic and interesting in its own right. The opening sequence, with the sinister uncle preparing for the arrival of his lovely young niece, sets an effective mood of doom and dread for the rest of the film. The youthful Barbara Shelley is more sensuous and provocative here than in any other role, except the prim wife turned voluptuous vampire in Dracula, Prince of Darkness. She's very convincing as the nice young woman whose repressed anger and jealousy erupt in the form of a psychically controlled ghost-leopard. She successfully takes the character of Leonora from sad, resigned wife to vengeful betrayed spouse to menacing cat woman by the end of the film. The exact details of her relationship to the supernatural leopard are a bit vague, since she apparently doesn't transform physically, but is able to unleash the phantom leopard on victims by her mental power. It manages to work pretty well, in spite of some vague details. The unexpected aspect of the movie today, that could not have been foreseen when the film was made, is the remarkable resemblance of actress Kay Callard as the psychiatrist wife of psychiatrist husband Robert Ayres, to the real life popular psychiatrist Dr. Joyce Brothers. This risks causing a bit of unintentional humor, but also adds to the odd intrigue of the story. The night time scenes of the dreary old house in the country ,and the dangerous back alleys of dockside London,are nicely filmed, with a very good sense of literal atmosphere: wind, rain, wet streets, cold pavements. A very interesting little film worth seeing if only for the treat of seeing such a very young and heartbreakingly beautiful Barbara Shelley.
