Maskarada aka Masquerade (1971) - Bostjan Hladnik

 

 An erotic drama about complicated love affairs and blackmailing. Dina, the young wife of elderly manager Gantar meets attractive student Luka and falls in love with him. All her further activity is submitted to one and only goal: to get Luka for herself. The first, uncensored version was not shown until 1982, in cinema Sloga where only porn movies were played at that time. Banned for over a decade because of its explicit sexual situations, when this film was released in Yugoslavia in 1983 the explicit scenes had become tame. Other than the notoriety it obtained through censorship, the film has an undistinguished story about the forbidden love affair between the older wife of a sports director and a young athlete. ~ Eleanor Mannikka, All Movie Guide

Sweet Movie (1974) - Dusan Makavejev

Dušan Makavejev's anarchic 1974 comedy goes even further than his previous W.R., depicting more trangressions than the average viewer's imagination could conjure up.

From Time Out London:
Potentially one of the most scandalous films ever made—except that it has been little seen outside France and has not aged well. Seemingly completely episodic, the 'plot' follows the adventures of a beauty queen (Laure), a certified virgin who escapes a disastrous honeymoon with the richest man in the world to join a group of carefree sensualists. The latter are the once-notorious Otto Muehl troupe, who delight in pissing and shitting as a public spectacle. This is cross-cut with the journey of the good ship SS Survival (which sports Karl Marx for a masthead) on the Seine. Laure herself sought legal suppression of certain shots which, in their blanked out form, ironically suggest even more sexual activity on her part. Sadly, this highly idiosyncratic melange of sex and politics, for all its liberating pretensions, only served to put Makavejev's career back a good few steps. –David Thompson

Bube u glavi aka This Crazy World of Ours (1970) - Milos 'Misa' Radivojevic

Quote:
Two emotionally distraught lovers find life is too much for them and enter an insane asylum. He is beaten and watches as she is raped. An attending physician fondles and kisses her during an examination in front of an X ray machine. The poor girl is driven to suicide, and the man learns too late of the psychological and physical assaults that led to her death in this tragic drama. This feature was invited to appear at the Venice Film Festival in 1970.

W.R. - Misterije organizma aka W.R.: Mysteries of the Organism (1971) Dusan Makavejev

From the Chicago Reader:

We may forget that the most radical rethinking of Marx and Freud found in European cinema of the late 60s and early 70s came from the east rather than the west. Indeed, it's hard to think of a headier mix of fiction and nonfiction, or sex and politics, than this brilliant 1971 Yugoslav feature by Dusan Makavejev, which juxtaposes a bold Serbian narrative shot in 35-millimeter with funky New York street theater and documentary shot in 16. The "WR" is controversial sexual theorist Wilhelm Reich and the "mysteries" involve Joseph Stalin as an erotic figure in propaganda movies, Tuli Kupferberg of the Fugs "killing for peace" as he runs around New York City with a phony gun, and drag queen Jackie Curtis and plaster caster Nancy Godfrey pursuing their own versions of sexual freedom. - Jonathan Rosenbaum
