Wake of the Red Witch (1948) dir. Edward Ludwig
Through a Glass Darkly (1961) dir. Ingmar Bergman
John Wayne plays an alcoholic, heartbroken, but inevitably likeable sea captain on-board a more subtle critique of colonial exploitation in the south Pacific. There's also a giant octopus that's probably a metaphor or something. Cut this gem with Bergman's Academy Award winner for Best Foreign Film** and you get a duel of schizoid protagonists that won't disappoint.
**This award most recently went to Dogtooth, an agreeably unsettling family drama/science-fiction/black comedy from Giorgos Lanthimos.
