Love Lasts Three Years

Marc Marronnier (Gaspard Proust) can't say why his marriage ended, only that his wife called him immature and left him for a well-known writer. A literary critic, he pours the wreckage into a manuscript arguing that love lasts three years and no longer. Then he meets Alice (Louise Bourgoin), the wife of his cousin, and Frédéric Beigbeder adapts his own novel with the same dry, confessional voice.
