Leonora Johnson (Barbara Shelley) is married to the unfaithful Richard (Jack May), but is secretly in love with former paramour, Dr. Brian Marlow (Robert Ayres of Battle Beneath the Earth), who is now married to Dorothy (Kay Callard of The Flying Scot). If that weren't enough of a mess, Leonora's crazy uncle (Ernest Milton), who keeps a leopard in the house, has convinced his niece that she is under a family curse and can turn into a leopard, or that she has a bond with it that can cause it -- or her -- to kill. Who the hell knows? In any case, when Brian tries to convince Leonora that she isn't really crazy and isn't growing claws, she decides it would be best to rid the world of her rival, Dorothy. This confusing mish mosh is a blatant rip off of Cat People, and while it's all overwrought and entertaining in a modest fashion, its chief strength is an excellent, intense performance by Barbara Shelley [The Gorgon] as the highly unlikable Leonora. Lily Kann is also effective as the uncle's housekeeper, Anna, and the various supporting performances are adept. But the movie is not really worth much in the long run.
Verdict: A monster movie with a most disappointing "monster." **.
