Last Tango in Paris (1972)

This film was originally released with an X rating in the US, which limited the audience. Around the world, however, it fared much worse. It was banned in numerous countries, on the grounds of indecency due to the graphic nature of the sex scenes, the age difference between Brando and his co star (He was in his 50s, she was 19), and the infamous butter rape scene. The film was even banned in Italy, where director Bernardo Bertolucci was from, until 1986. Prints of the film were also burned and Bertolucci was sentenced to 4 months in prison for obscenity.
