The Creeper (1948) – Jean Yarborough.

During an exploratory expedition in the shadowy backwoods of the West Indies, a conflict between two rival scientists fatefully escalates, finally coming to a terrible climax following the discovery of a malign bioproduct that disturbingly transforms all who take it into absolutely feral, feline killers! With the exception of The Uncanny, Yarborough's claw-some cult classic The Creeper is one of all too few Creature Features to have have a profoundly neurotic protagonist with a hugely debilitating case of extreme pussyphobia! I have long been an admirer of our fuzzy, feline companions, so I am not exactly unbiased on the subject of marvellous moggies, but I feel that only the most abject pussyphobe would fail to be beguiled by the slinky, shape-shifting shenanigans presented by splendidly kooky B-shocker The Creeper. While Yarborough's vintage Freudian fright-flick is prone to lapses of expository blarney, The Creeper has a winningly hysteria-laden, off-beat quality, and often captivates by its compelling usage of eerie In-camera trickery.
