Sometimes, the less you know about a film, the more you are likely to enjoy it. This is one of those times. All I really knew about the movie was that it was French and appreciated by public and critics alike. That was enough for me and ensured that the surprises really were surprises.
You need to know more? OK, the film is based on a 1985 short Story by Ruth Rendell and the directed by François Ozon ("Potiche"). What? You want more? The core of the film is the relationship between characters - the husband and best friend of the recently deceased Laura - ably acted by Romain Duris and Anaïs Demoustier.
Oh, gosh. You want to know what it's about? Let's just say that it's an amusingly serious - if this is not too oxymoronic - examination of sexual identity. And that really is all I'm going to tell you about this enjoyable movie. Now see it for yourself.
