Mathieu Amalric (The Diving Bell and the Butterfly, Quantum of Solace) writes, directs and stars in this tightlipped erotic thriller based on the book by Belgian crime king Georges Simenon. Julien (Amalric) is a discontented husband and father engaging in monthly hookups with his sexy (also married) mistress. Sounds like a very French thing to do. So why are the police questioning him? This slow-burn thriller features plenty of flashbacks and expends about half its run-time before we're even privy to what crime has been committed. Unfortunately, by that point, a lot of the tension has been used up. Fortunately, the film is only 76 minutes long, so things get wrapped up pretty quickly after that. Audience members will either appreciate the film's mysterious atmosphere or lament the lack of concrete answers.76 minutes R.
