Kagemusha

Kagemusha is a 1980 film by Akira Kurosawa. In Japanese, kagemusha is a term used to denote a political decoy. It is set in the Sengoku period of Japanese history and tells the story of who is taught to impersonate a warlord in order to dissuade opposing lords from attacking the newly vulnerable clan. The warlord whom the kagemusha impersonates is based on daimyo Takeda Shingen, and the film ends with the climactic 1575 Battle of Nagashino.
