Love Lasts Three Years (2011)

Original title: L'amour dure trois ans

A heartbroken literary critic turns his despair into creativity following a bitter divorce, only to encounter an enchanting beauty who poses a major challenge to his newfound cynicism. Marc Marronnier thought his marriage was going well until his wife deemed him immature, and left him for a high-profile writer. Devastated, he began filtering all of his heartache into a misanthropic manuscript decrying the virtues of true love. But later, when Marc falls hard for his cousin's radiant and gorgeous wife, his entire life is turned upside down. Louise Bourgoin and Gaspard Proust star in a film by actor and author-turned-director Frederic Beigbeder.
