Ran (乱, transl. "chaos" or "turmoil") is a 1985 epic period drama film directed, edited and co-written by Akira Kurosawa. The plot derives from William Shakespeare's King Lear and includes segments based on legends of the daimyō Mōri Motonari. The film stars Tatsuya Nakadai as Hidetora Ichimonji, an aging Sengoku-period warlord who decides to abdicate as ruler in favor of his three sons.
