'Love'
Directed by Gaspar Noé

Noé, a director known to push a button or three (Irreversible, Enter the Void), certainly brought attention to his 2015 film, Love. The movie is filled with unsimulated sex, but that's not all. Noé shot the movie in 3D. But it was the film's poster that generated the most heat before it screened at Cannes.
