On the surface, the Cannes Film Festival is the classiest of the annual film showcases; it's French, after all. But in reality, it's known for rowdy audiences who aren't afraid to boo down Hollywood sweethearts like Sofia Coppola, or give 20-minute standing ovations to loose-cannon documentarians like Michael Moore. Sharon Waxman just got back from Cannes, which wrapped up last night, and she joins to report on all the festival's biggest films and oddest happenings. Waxman is the founder and CEO of TheWrap.com.
