Sergio Martino’s All the Colours of the Dark is a cult Italian horror-giallo hybrid starring Edwige Fenech. Mixing satanic cult terror with surreal dream sequences, the film blends psychological breakdown, folk-occult ritual, and giallo stylization. A defining entry in 1970s Euro-horror, it remains a hypnotic fusion of paranoia and exploitation.

ALL THE COLOURS OF THE DARK, is Sergio Martino’s dark and dazzling 1972 giallo masterpiece. Italian celluloid icon Edwige Fenech (THE STRANGE VICE OF MRS WARDH, TOP SENSATION) leads an all-star cast as Jane Harrison, a nervous housewife plagued by nightmarish visions of her own bloody murder. To cure her hellish fantasies her bewitching neighbour Mary (Marina Malfatti, THE RED QUEEN KILLS SEVEN TIMES) initiates Jane into a Satanic coven. But when she witnesses Mary’s ritual sacrifice at a candlelit black mass, Jane’s diabolical dreams start to come true. Who is the blue-eyed phantom stalking her and has she already witnessed her own death? Genre acolytes George Hilton, Ivan Rassimov and Susan Scott join the unholy alliance in Martino’s tense and paranoid fever dream. Presented in ravishing high-definition and with a haunting score from Bruno Nicolai, satanic panic has never been so stylish!
