'Cold Blooded Beast' (1971) – Fernando Di Leo.

As lurid exploitation concepts go, Maestro Fernando Di Leo's ominously oneiric, One screw over the Cuckoo's Nest, grisly-gorgeous, glamour girl-garlanded Giallo remains a dazzlingly demented, floozie-flaying, midnight movie doozie! Within a vast, luxuriously plush clinic for nubile-neurotic, frequently frisky, uncommonly quixotic, lividly libidinous, mentally muddled women, a darkly-garbed, kaleidoscopically cruel killer silently stalks the weapon-festooned hallways, and for reasons obscure proceeds to get gruesomely medieval on these delectably displayed derrières! The world renowned master of the pulse-pounding Poliziotteschi clearly has little difficulty smoothly shifting gears from bellicose, bullet-shredded, gearbox-thrashing Euro-crime tropes to the more scurrilous stalk and gash mania of a gore-soaked Gialli!

While 'Cold Blooded Beast' is rather more fleshy-fantastic Jess Franco than moodily macabre Mario Bava, boisterously eschewing artisan set-pieces for remarkably explicit rumpy-pumpy, and grisly blunt force trauma! Di Leo's deliciously degenerated vintage blood-spiller is a ferociously fun grindhouse Giallo, its lack of cinematic subtlety, and the director's explicitly voyeuristic camera allows for penetrating illicit thrills, and plentiful audacious kills, and excluding Kinski's bafflingly sedate performance, there's much gruesome grist for the true blue, grue-seeking Gialli aficionado to enjoy, not least being the sympathetically slinky, mesmerizingly marvellous, sensually savage performance from raven-haired beauty Rosalba Neri, all this sublimely sinister slashing energized by an especially scintillating score by maestro Silvano Spadaccino.
