Kagemuša

In this dazzling epic from Akira Kurosawa, a petty thief named Kagemusha (Tatsuya Nakadai) gets saved from a death sentence because he resembles the warlord Shingen Takeda (also Nakadai). The warlord has been fighting two other leaders for control of 16th-century Japan and impersonators often take his place during battles to put him out of harm's way. Because of Kagemusha's strong physical similarities to the warlord, he's a perfect choice for a "shadow warrior." However, the arrangement suddenly changes when Shingen gets fatally wounded while watching a battle. Adhering to Shingen's final wish, the warlord's men keep the death a secret, and Kagemusha struggles to transform himself from a criminal into a leader. (official distributor synopsis)
