Rostros (Faces)

An old married man leaves his wife for a younger woman. Shortly after, his ex-wife also begins a relationship with a younger partner. The film follows their struggles to find love amongst each other.

This was one of the most influential films of the 1960s, if you consider how it inspired Robert Altman and Woody Allen, as well as employing Steven Spielberg as a production assistant while he was still making short films and had not yet broken into feature films.

How well the film has aged is debatable. While its influence is clear, the film itself is not necessarily the most fun. Some have called it "meandering", and it is hard to believe that at one point Cassavetes had a six-hour cut (allegedly).
