The Idiots (1998)

Director: Lars von Trier

Non-titilatting title aside, the Danish took on screen-sex to new heights (or is it depths?) withThe Idiots. The film follows a group of adults who have vowed to detach from any semblance of normality and embrace their inner idiot. In order to achieve this, the group members take on a disabled persona that allows them to lose all inhibitions, which means that no impulse, however outlandish, is off limits.

This plays out in a risqué way at one of the members' birthday party, whose birthday wish is "a gang-bang" (as explicitly spelled out in subtitles). The result is a playful and somehow sentimental orgy, which looks as paradoxical as it sounds.
