Ran (1985)

If the role of the fool doesn't clue you in early on, the best way to approach Ran is to imagine yourself an audience member at a theatre and the film frame an elaborate stage. That way the pacing, framing, and blood, etc, will make perfect sense. Even the clouds are dramatic.
It's the story of a Sengoku-era Lord, Hidetora, with three sons of different temperament. He divides his Kingdom between each of them but the power, jealousy and greed tears the family stability apart.
Toru Takemitsu's minimalist score adds haunting atmosphere.
If you get confused about who's who, just remember the colours.
