A list of films that had an impact on the rating system regardless of being a big budget Hollywood film or filmed on a rice farm in China.
Most films feature on film historian Tim Dirks’ column at http://blogs.amctv.com/movie-blog/2009/04/sex-in-the-movies-the-list.php
I have removed The Immoral Mr. Teas (1959) and Porky’s (1982) as they don’t feature on The Auteurs. I have replaced them with Midnight Cowboy (1959) and National Lampoon’s Animal House (1978) respectively. I feel those two films are acceptable replacements. I have also added Blow-Up (1966) as I feel that film also challenged the system.
Ecstasy (Machaty, 1933) – The first non-pornographic film to depict a sex act
The Outlaw (Hughes,1943) – The Howard Hughes film that was delayed for years thanks to Jane Russell’s cleavage and challenged the Hays Code
The Lovers (Malle, 1958) – Inspiration for Supreme Court’s Overturning Obscenity Laws
Midnight Cowboy (Schlesinger, 1959) – The first X-rated feature to win Best Picture
Blow-Up (Antonioni, 1966) – Director Michelangelo Antonioni chose to release it without an MPAA seal rather than cut the nude scenes
A Clockwork Orange (Kubrick, 1971) – The X-rated Oscar nominee that shocked the world with graphic sexual content and was banned in Britain for 30 years regarding copycat crimes
National Lampoon’s Animal House (Landis, 1978) – Along with Porky’s (1982), the true start of the teen sex comedy phenomenon
Caligula (Brass, 1979) – Hollywood’s first big-budget sexploitation epic
Henry & June (Kaufman, 1990) – The first major studio picture with an NC-17 rating, revised rating designed to distinguish serious erotic films from straight-on porn
Romance (Breillat, 1999) – The first mainstream film to feature an erect penis.
Shortbus (Mitchell, 2006) – Porn with a serious storyline and contains hardcore images of sexual intercourse (gay and straight), masturbation, S&M, an orgy, and a menage a troisRead less
