Behind Convent Walls (1977, It.) (aka Interno di un convento)

This film (based upon French author Stendhal's Promenades dans Romanes) from director Walerian Borowczyk - one of a number of "Convent Erotica" sexploitation (or nunsploitation) films, told about an early 19th century nunnery run by Abbess Flavia Orsini (Gabriella Giacobbe) who vainly sought to repress the sensual urges of its sexually-repressed nuns (who engaged in lesbianism, illicit sex, masturbation, and other forms of sexual experimentation); the film's most notorious scene was one in which love-starved nun Sister Clara (the director's wife Ligia Branice), the niece of the Mother Superior, found a piece of wood on some window-pane glass and carved herself a large wooden dildo (with its handle engraved with the face of Jesus Christ) for masturbatory purposes

The Deep (1977)

Director Peter Yates' suspenseful thriller about a treasure hunt in the Caribbean was based on the Peter Benchley novel - appearing soon after the success of Jaws (1975); it was a box-office hit - although mediocre film that was credited (?) with initiating the wet T-shirt craze of the 70s; the film's iconic image, extremely well-publicized and exploited (both for the film and poster sales), was of wet T-shirt wearing diver Jacqueline Bisset (as Gail Berke) during the opening 10-minutes credits sequence while she scuba-dived in the beautiful tropical waters of Bermuda and then emerged out of the water and sat on the edge of the dive boat; producer Jon Peters was quoted as saying: "That T-shirt made me a rich man"

Equus (1977)

Kentucky Fried Movie (1977)

John Landis' film was created by the ZAZ (David Zucker, Jim Abrahams and Jerry Zucker of Airplane! (1980) fame) trio of comedy writers who were known as The Kentucky Fried Theater when they performed as a Wisconsin comedy troupe; it was essentially an unrelated, blatantly sexual, and racially insensitive collection of comedy sketches with no unified plot; the entire film pushed the boundaries of its time by parodying and satirizing pop-culture of the 1970s, including TV commercials, drive-in movies, school educational films ("Zinc Oxide"), martial-arts films, courtroom TV shows, female blaxploitation action films ("Cleopatra Schwartz"), disaster films, and soft-core pornography advertisements; the almost two-dozen segment titles included: "A Fistful of Yen" (a Bruce Lee Kung-Fu parody), "The Joy of Sex", "Science and You", "Danger Seekers", "Sex Record" (pictured with Sharon Kaugh and Jack Baker), "Household Odors", "United Appeal For The Dead", "Courtroom", "Feel-A-Round", "Catholic High School Girls In Trouble" (pictured with Uschi Digard as the character "Woman in Shower"), and even featured faux coming-attractions

Young Lady Chatterley (1977)
AND
Lady Chatterley's Lover (1981)
AND
Lady Chatterley (1992)

Producer-director Alan Roberts' X-rated soft-core film starred Harlee McBride as Cynthia Chatterley (the niece of the original Lady Constance Chatterley) in an updated adaptation of D.H. Lawrence's once-scandalous 1928 novel Lady Chatterley's Lover about carnal pleasure set in Beverly Hills; it contained scenes of eroticism in the bath with the chambermaid, in a car, and with herself full-frontal before a mirror; it was followed by a similar sequel in 1985 by Playboy Productions titled Young Lady Chatterley II, again with Harlee McBride (and this time with Adam West of TV's Batman)

Emmanuelle's Dutch-born star Sylvia Kristel appeared in the 1981 retelling directed by Just Jaeckin as sexually-unfulfilled Constance Chatterley who was involved in a husband-sanctioned torrid affair with the virile and rugged gardener Mellors (Nicholas Clay)

Also, British director Ken Russell directed a well-executed and acted, four-hour BBC mini-series adaptation in 1992, with Joely Richardson and Sean Bean

Coming Home (1978)

Get Out Your Handkerchiefs (1978, Fr./Belgium) (aka Préparez Vos Mouchoirs)

Halloween (1978)

Director John Carpenter's low-budget slasher film, at its time, was the most profitable independent film in industry history; the landmark film set in motion the Puritanical, psycho-pathological principle that surviving murder by a psychopathic killer was directly related to the degree of one's sexual experience; it also asserted the allegorical idea that sexual awakening often meant the literal 'death' of innocence (or oneself); in the film's opening sequence (filmed from the POV of the young killer wearing a Halloween mask) - after teenaged Judith Myers (Sandy Johnson) had sex with her boyfriend Tommy (David Kyle), the six-year-old killer Michael Myers (Will Sandin as boy) took a large butcher knife, entered his near-naked sister's bedroom where he found her brushing her hair in front of a vanity table; after he surveyed her bedsheets, she turned and recognized her brother: "Michael!" and although she tried to defend herself, he furiously stabbed her to death in a brutal murder, and her bloodied body tumbled to the floor; in this film, the murders often occurred after sexual encounters when victims were distracted and off-guard - note in the middle picture the dark silhouette of the serial killer Michael Myers as teenaged Lynda (P.J. Soles) and her boyfriend Bob (John Michael Graham) made love in a bed next to a jack-o-lantern, before he was killed and she was strangled with a phone cord; the virginal baby-sitting title character Laurie (Jamie Lee Curtis) was able to escape mostly unscathed (as did the asexual Dr. Loomis and the young pre-teen Tommy Doyle), but others who were more promiscuous and sexually-charged were less fortunate and suffered deadly consequences as stalked victims

I Spit on Your Grave (1978) (aka Day of the Woman)

Midnight Express (1978)

In director Alan Parker's harrowing drama about an American imprisoned in a brutally-hellish Turkish prison for hash possession, Billy Hayes (Brad Davis) was stripped at gunpoint and forced to endure beatings, rapes, and torture by sadistic guards; in one scene, the sexually-desperate Billy asked his girlfriend Susan (Irene Miracle) to show him her breasts by pressing them against the partition's glass so he could kiss them and pleasure himself

Nicole (1978) (aka Crazed or The Widow's Revenge)

Often, an impossible-to-find, poorly-made film such as this one (until released on DVD to capitalize on its rarity) will still be touted as featuring 'one of a kind' topless nudity of one of its characters; in this case in writer-director István Ventilla's erotic thriller, it was the appearance of 24 year-old Catherine (credited as Cathy) Bach (famous in coming years as Daisy Duke in the classic TV show The Dukes of Hazzard from 1979-1985) as young and innocent Sue, who was obsessed over by slightly mad, rich lesbian widow Nicole (47 year-old Leslie Caron) with a brief breast groping (possibly with a body double) - and then killed by her trained Great Dane guard dogs
