Le Dos Au Mur (aka Back To The Wall) (1958)

When a man (Gerard Oury) discovers his wife (Jeanne Moreau) is having an affair, he concocts a diabolical plot to get revenge on his wife and her lover (Philippe Nicaud). But the plan backfires resulting in dire consequences for all involved. Based on the novel DELIVREZ NOUS MAL by Frederic Dard and directed by Edouard Molinaro (LA CAGE AUX FOLLES) in his feature film debut. A detailed and precise film noir dealing with a domestic triangle that I found compelling despite its methodical pacing. It's a chilly film and its glacial characters are hard to latch on to but Molinaro creates an unsettling atmosphere that you know won't end well.  Nicely acted and fans of film noir should be pleased. With Claire Maurier and Gerard Buhr.
