After his divorce, Marc Marronier (Gaspard Proust) dumps all his cynicism into a book that is summed up by its title: Love Lasts Three Years. As his work is rejected by several publishers, he meets the amazing Alice (Louise Bourgoin). Her freshness blows away his conviction that he's done humanity a good service by waking them up to the masquerade that is love. As their relationship chips away at his pessimism, Marc's book is finally published. Protected by a pseudonym, he manages to keep Alice from guessing he's the author of the ideas everyone is talking about. But for how long?

Debut by Frédéric Beigbeder adapted from his second novel of the same name. «Love Lasts Three Years» has the complete range one expects from a pretty-boy womanizer. The movie is charming, funny, with a stylized aesthetic. The writer's touch is evident, with good dialogue and snappy comebacks, all presented in chapter style because it's hard to change one's ways.
