'How to Have Sex': A Wild Summer Holiday Takes a Dark Turn at Cannes

"How to Have Sex," a film premiering in the Un Certain Regard competition at Cannes, follows three British teenage girls on a summer holiday in Malia, Greece, where they party, get wasted, and hook up. The cast's ability to appear heavily intoxicated in front of the camera was crucial to the film's casting process, with the director even spinning them around before every drunk scene. The story takes a darker turn, dealing with sexual consent and the gray area of assault.
