Bushido (1963)

In this classic piece of Japanese martial arts cinema, modern-day businessman Susumu (Kinnosuke Nakamura) ponders seven generations of his samurai family, their codes, traditions and history of stark violence, as he comes to terms with his own place in the lineage. Nakamura takes on multiple roles, portraying not only Susumu, but his succession of ancestors, stretching back through 350 years of Japanese feudal history.
