Despite all the very high-profile films in competition, this was the 2013 Cannes Film Festival’s most talked about movie. Besides winning the festival’s highest honor, the Palme d’Or, Blue Is the Warmest Color generated a great deal of buzz for the incredible performances of its stars, Adèle Exarchopoulos and Léa Seydoux, and its stunning, ten-minute, likely unsimulated sex scene (note the NC-17 rating). Directed by Abdellatif Kechiche and based on a graphic novel, the film tells the tumultuous story of a teenager who falls for an older, blue-haired college art student. It opens on October 25 – just in time for some very hip people to find their perfectly niche Halloween costume.
