La Notte

"Marcello Mastroianni and Jeanne Moreau are affluent but emotionally estranged spouses in Michelangelo Antonioni's 1961 post-neorealist classic La Notte. After ten years of marriage, Giovanni, a successful novelist, and his wife Lidia have grown apart. He is no longer attracted to her, and she finds him boring and self-absorbed. During the course of a single day, they are faced with heartache, desperation and personal loss. When the night comes, both are tempted by thoughts of infidelity but ultimately return to each another. Unable to come to terms with their emotions, they are left to ponder the fate of their marriage, and unstable union destroyed by indifference of habit and impenetrable loneliness." - from DVD Cover

I wonder if Stanley Kubrick has been inspired from this to have his Eyes Wide Shut. Another film seems very familar in the atmosphere to me is "Wild Strawberries".
