Anal sex in Last Tango

Last Tango in Paris stars Marlon Brando as a grieving window who loses himself in a passionate anonymous affair with a young French woman - played by Maria Schneider - who is engaged to another man.

There is much nudity in the film but the one scene that caused the most controversy was the one in which Marlon Brando used butter as a lubricant prior to anal sex.

Schneider at the time of the film gave many frank interviews about her colourful sex life and appeared to be unconcerned by the uproar the film created but later on she was to change her stance.

Of the butter scene she is quoted as saying in a Daily Mail interview: "I should have called my agent or had my lawyer come to the set because you can't force someone to do something that isn't in the script, but at the time, I didn't know that. Marlon said to me: 'Maria, don't worry, it's just a movie,' but during the scene, even though what Marlon was doing wasn't real, I was crying real tears. I felt humiliated and to be honest, I felt a little raped, both by Marlon and by Bertolucci [the director]. After the scene, Marlon didn't console me or apologise. Thankfully, there was just one take."

She remained friends with Brando after the film although she admitted they did not speak of the film as Brando too sought to disassociate himself from the movie.

After her death Bertolucci said: "Her death came too soon, before I could hold her again tenderly, and tell her that I felt connected to her as on the first day, and for once, to ask her to forgive me. Maria accused me of having robbed her of her youth and only today am I wondering whether there wasn't some truth to that.”
