Legendary Japanese director Akira Kurosawa’s first samurai movie is considered one of the greatest and most influential films of all time. It was famously remade as the Western The Magnificent Seven, first in 1960 by John Sturges and last year by Antoine Fuqua. Its themes echo in today’s comic-book movie world. Set in 16th-century Japan, it’s about a group of helpless farmers who enlist seven samurai warriors to defend them from bandits intent on stealing their harvests. At 3 hours and 27 minutes, it’s Kurosawa’s longest movie, and making it was often a long, expensive battle, leading Toho Studios to shut down production twice. But Kurosawa got the kind of realism, drama, action and humor that helped carve out his reputation as a master.
