The Devils (1971, UK)

In Ken Russell's blasphemous, shocking, repulsive and flamboyant film about the repressive 17th century when sexuality was equated with Satanism (an adaptation of Aldous Huxley's "The Devils of Loudon"):

• the demented, overwrought and offending excesses: sexual debauchery, a hunchbacked, sexually-tormented and possessed Mother Superior Jeanne (Vanessa Redgrave)
• Mother Jeanne's unfulfilled, warped sexual desires (and vivid fantasies) for the town's womanizing, vain, rebellious liberal-activist priest Father Urbain Grandier (Oliver Reed)

Crazed and Sexually-Tormented Mother Superior Jeanne

• the so-called "Rape of Christ" sequence (heavily censored), when naked nuns engaged in orgies and self-flagellating masturbation with a large-scale effigy of Jesus
• the torture, hideous exorcistic practices, and the killing of Huguenots

Father Grandier Burned at Stake

• the brutally-realistic execution of Father Urbain Grandier by burning at the stake after he faced questioning and persecution for his 'diabolic possession' of the local repressed Ursuline nuns
