Kagemusha

Kagemusha is a 1980 Japanese epic jidaigeki film directed by Akira Kurosawa. It is set in the Sengoku period of Japanese history and tells the story of a lower-class petty thief who is taught to impersonate the dying daimyō Takeda Shingen to dissuade opposing lords from attacking the newly vulnerable clan. Kagemusha is the Japanese term for a political decoy, literally meaning "shadow warrior". The film ends with the climactic 1575 Battle of Nagashino.
