It's a dark and stormy night ... what else in a horror movie ? ... when
the owner of a sinister looking mansion or castle, Edmund Brandt (Ernest
Milton)
has called his niece and only heir, Leonora Brandt (Barbara
Shelley) to visit him alone. He's about to tell her about the
family curse, the Brandt curse.
Since 700 years they have had a crave for raw meat, having a connection
to a - or turning into a - Killer Cat (leopard or cheetah) ?
Against her uncle's wishes Leonora brings her slimy husband Richard
(Jack May) and their 2 friends Allan (John Lee) and Cathy (Paddy Webster)
and it doesn't end well as a Killer Cat kills both Richard and her uncle.
Richard cheated on Leonora with Cathy and Leonora now thinks she has
inherited the curse and that the cat kills on her command.

Now, Dr. Brian Marlowe (a wooden Robert Ayres) a psychiatrist
and also the ex-boyfriend of Leonora takes her to a sanatorium in London,
for rest
and snapping out of her delusions. He's sure that her delusions are
caused by her husband's infidelities and his violent death by a roaming
beast,
but Leonora is sure that the Leopard is there with her, in London, at
the sanatorium, just outside her window and that her hands sometimes
turns
into claws. Brian trusts her and even take her home to meet his sweet
wife Dorothy (Kay Callard), Dorothy couldn't possibly be in any risk,
could she ?
There's some clunky acting here and there but Barbara
Shelley is great as Leonora and old Edmund Brandt's housekeeper Anna
(Lily Kann) was fine
and the ending scenes on the streets in the London docklands were quite
atmospherical and effective. But, hey, was it a Leopard or a Cheetah
?
