LOL (Laughing Out Loud) is a 2008 French comedy film directed by Lisa Azuelos and starring Sophie Marceau, Christa Theret, and Alexandre Astier. Written by Azuelos and Delgado Nans, the film is about a teenage girl whose life is split between her studies in a Parisian high school, her secret diary, her parents, her friends, and her boyfriends. Christa Theret received a César Award nomination for Most Promising Actress in 2010. The movie is heavily inspired by La Boum, which starred Marceau as the teenage character. After the film's great success, several actors from the cast took part in Fort Boyard in 2009, a French TV show aimed at raising money for an association.
