In this version of the Shakespeare tragedy, the king is a 16th-century warlord (Tatsuya Nakadai as Lord Hidetora) who decides to retire and divide his kingdom evenly among his three sons. When one son defiantly objects out of loyalty to his father and warns of inevitable sibling rivalry, he is banished and the kingdom is awarded to his compliant siblings. The loyal son's fears are valid: a duplicitous power struggle ensues and the aging warlord witnesses a maelstrom of horrifying death and destruction. Although the film is slow to establish its story, it's clear that Kurosawa, who planned and painstakingly designed the production for 10 years before filming began, was charting a meticulous and tightly formalized dramatic strategy. As familial tensions rise and betrayal sends Lord Hidetora into the throes of escalating madness, Ran (the title is the Japanese character for "chaos" or "rebellion") reaches a fever pitch through epic battles and a fortress assault that is simply one of the most amazing sequences on film.
