I have been very disappointed seeing that film. The story of a man who is a writer, who usually writes thrillers, on the edge of disaster, who asks another writer with no publisher to share the benefits of a mutual writing. Having to involve a perfect murder like they usually write was a good idea, it was just not well developed. Moreover, the emphasis on the overexposure of the images is ad nauseam. The violence, the blood, the sadistic attitudes of the characters might have been in the book (which I admit I did not read) but it did not show well on the big screen. There could have been good ideas, the performance as an actor of Bernard Giraudeau as Brice Kantor is undeniably good; he has this ability to play all kinds of characters and this one might not be his best but he excels in playing the bad guy. Karin Viard is yet again a bad actress, when she gets angry, it is just not credible; and François Cluzet should stay with Chabrol when he accepts his films.
