The film, which won the Palme d'Or at the Cannes Film Festival in 2013, wiped away everything that had gone before it. From Swedish nudes in 1953 ( Summer with Monika) to the butter-based penetration of 1972 ( Last Tango in Paris) to crazy irascible beach-side sessions in 1986 ( Betty Blue), nothing screams 'art house' more than a smartly directed and gamely acted sex scene.
