The title is a French expression that means something that backfires. This 1957 film had four great actors: the seductive French actress Michele Morgan, Daniel Gelin, Peter Van Eyck, and the great Bernard Blier. It was based on a novel by British writer James Hadley Chase. In this film, Van Eyck plays the role of a formerly rich man who's lost his fortune. One night, he emerges drunk from a nightclub on the French Riviera and is nearly run over in the street. A young, somewhat naive man (Gelin) helps him get home to his lavish villa which he shares with his wife, an absolute ice princess (Morgan). Van Eyck offers him a job as his chauffeur. Gelin becomes attracted to Van Eyck's lovely wife. Van Eyck is faced with financial ruin and a wife who is incapable of love and so commits suicide. To punish his icy wife, he removes the suicide clause from his insurance policy, meaning that to collect his money, his wife will have to hide the suicide and make it look like her husband was murdered and he tells her about it before he kills himself. The trick is to make it look like someone else killed him, not her. She enlists Gelin in the scheme who is a slave to her icy charms. But they do too good a job in making it look like someone else murdered her husband and the the police detective (Blier) suspects the wife and her boyfriend. Morgan plays a beautiful icy woman every bit as evil as Barbara Stanwyck in Double Indemnity. An American version of this film could be interesting.
