Blue is the Warmest Colour (2013)

Art house movies. We get it. They do sex. That's their thing. 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. Then came Blue is the Warmest Colour.
