Deep Water(Eaux Profondes)

We see the icy beauty Isabelle Huppert dancing romantically with a man at a party. However, her husband isn't her dance partner, but rather the stoic Jean-Louis Trintignant who is staring quietly with an ominous gaze from a corner. So starts Michel Deville's provocative thriller about a dysfunctional open marriage that turns lethal when the husband is suspected of murdering his wife's lovers. Patricia Highsmith's novel about a marriage's slow disintegration through mutual destruction even played a major influence on Gillian Flynn's hit novel Gone Girl.
