Salò (a.k.a. 120 Days of Sodom, 1975)

Director: Pier Paolo Pasolini

There are sex scenes that evoke beauty and tender emotion, and then, on the polar opposite end of the sexual spectrum, lies Salò. Pasolini's art house film unflinchingly portrays 18 teenagers forced into a depraved exploration of sexuality you almost wish had been left unexplored, which is why we are in no way urging you to watch this film.

It is not sexy by any means, but it is an undebatably debaucherous, uncomfortably violent orgy from start to finish, which is why we couldn't leave it out. Plus, Pasolini embraces the idea of an orgy with a perversion and unmatched panache that almost elevates this controversial film to art. Almost.
