Behind Convent Walls (1977)

Smut-peddler or provocateur, the jury is still out on director Walerian Borowczyk, but they remain hung. In Behind Convent Walls (1977), his take on religion, Borowczyk explores the perversions and pleasures seething beneath the sacred waters of a holy convent. And there's plenty to keep him (and audiences' hands) busy. If you like half-naked or panty-clad nuns, this is your picture. But even the most skin-loving viewer may lose their erection when Olivia Pascal fashions her own personal dildo with the head of Christ that she proceeds to shove up her glory hole. Maybe that should remain behind convent walls.
