Alain Resnais, one of the towering figures of the French New Wave, demonstrates he still has plenty to say in this drama based on a novel by Christian Gailly. Marguerite (Sabine Azéma) is a successful dentist with a busy practice and an offbeat hobby, flying small airplanes. One day, while running errands, Marguerite loses her wallet, and it's found by Georges (André Dussollier), a seemingly happy man with a wife, Suzanne (Anne Consigny), and two children (Vladimir Consigny and Sara Forestier). As Georges looks through the wallet and examines the photos of Marguerite, he finds he's fascinated with her and her life, and soon his curiosity about her becomes an obsession. Georges' attempts to integrate himself into Marguerite's life begin to alarm her, and she hires a private security team (Mathieu Amalric and Michel Vuillermoz) to keep him away, but Georges is determined that his new love for her will not be denied. Les Herbes Folles (aka Wild Grass) received its world premiere at the 2009 Cannes Film Festival.~ Mark Deming, All Movie Guide
