Product Description:
One of the most thrilling movie epics of all time, Seven Samurai (Shichinin no samurai) tells the story of a sixteenth-century village whose desperate inhabitants hire the eponymous warriors to protect them from invading bandits. This three-hour-plus ride from Akira Kurosawa—featuring legendary actors Toshiro Mifune and Takashi Shimura—seamlessly weaves philosophy and entertainment, delicate human emotions and relentless action, into a rich, evocative, and unforgettable tale of courage and hope.
