'Sadomania' (1980) – Jess Franco.

Young newly-weds foolishly trespass the sprawlingly mountainous grounds of an all-women labour camp, evilly run by gleefully sadistic warden Ajita Wilson. The loving couple's spontaneous search for adventure leads them darkly into a vile labyrinth of unimaginable cruelty, sexual perversion, brutal cat-fights, sordid flesh peddling, and steamily uninhibited prison cell nookie! There's an expressly thrilling interlude whereby a nubile blonde inmate is ruthlessly hunted down in a swamp, which excitingly recalls the joyfully exploitative sensibilities of, Al Adamson & Ted V. Mikels. I think it was Kazan who playfully opined that all you need to make a film is a lusty hot-panted chick and a plastic crocodile! I still have a great fondness for Franco's lurid Alicante period, and forgiving the tawdry text, these exuberantly wanton W.I.P larks often provide an illicit panoply of virtuosic eccentricity! To whit, 'Sadomania' boasts a bravura sequence with an uncommonly frisky Alsatian that still gives me paws for thought!
