Monsieur Ripois (aka Knave Of Hearts) (1954)

A Frenchman (Gerard Philipe) in London is a chronic womanizer. He'll say and do anything to get a woman to sleep with him. As his wife (Valerie Hobson) is away getting a divorce, he attempts to seduce her best friend (Natasha Parry) by playing on her sympathies and telling her about his sex addiction. It's fortunate for Rene Clement's amusing comedy that the immensely appealing Gerard Philipe is playing the title role because the character is an amoral and selfish creature with little concern for the feelings of his conquests. But with the charming Philipe in the part, it's hard not to like him and by the end of the movie, we're almost sympathetic to him. It's almost a rough blueprint for ALFIE (1966). Clement shot the film twice, in English and in French, and I only had access to the French language cut but since the British actors are speaking French rather than being dubbed, it was okay. With Joan Greenwood, Margaret Johnston and Germaine Montero.
