October 14, 1972: that date should become a landmark in movie history comparable to May 29, 1913 — the night Le Sacre du Printemps was first performed — in music history. There was no riot, and no one threw anything at the screen, but I think it's fair to say that the audience was in a state of shock, because Last Tango in Paris has the same kind of hypnotic excitement as the Sacre, the same primitive force, and the same thrusting, jabbing eroticism. [...] Bertolucci and Brando have altered the face of an art form. Who was prepared for that?
