Exorcism (1975)

Jesus Franco wrote, directed, and starred in Exorcism (1974), a Euro-sleaze classic chockfull of sex, nudity, sadism, blood, and black-magic rituals. Franco’s wife and muse, Lina Romay, is Anne, who works at a French porno magazine and, along with her sadistic lesbian lover Lynn Monteil, participates in elaborate black-mass-themed orgies staged by the magazine. Franco plays Mathis Vogel, a.k.a. Laforgue, a defrocked priest and self-styled exorcist who witnesses one of the orgies and, believing it to be real, hunts down the participants and performs exorcism by torturing his victims, hanging them with chains, and cutting out their hearts. Sometimes you have to be cruel to be kind.
