This movie (not to be confused with another Carroll Baker vehicle “Kiss Me, Kill Me” aka “Baba Yagi–the Witch”)is Umberto Lenzi’s follow-up to his groundbreaking classic “Paranoia”. It came out the same year as Dario Argento’s “The Bird with Crystal Plumage” (the film which started the deluge of Italian gialli) and was produced by the Martino brothers, who later made a number of interesting giallo films (usually featuring Eugenio Martino’s alluring mistress, Edwige Fenech). It stars Carroll Baker, demonstrating her acting chops here by playing a character that is the exact opposite of the naive victim she played in “Paranoia”, and it also features two excellent, native European actors–Jean Loius Trintignant and the gorgeous Erica Blanc. The script is surprisingly well-written and full of suspense and genuine surprises. It is a clever variation on the classic French film “Diabolique” with a decadent, high-society husband (Tritignant), wife (Blanc), and mistress (Baker) all crossing and double-crossing each other. It cleverly plays with the viewers awareness of the earlier film before throwing in an unexpected curve.
