Factual error: Toshiro Mifune's character, Kikuchiyo, travels to the bandits' camp and steals one of their two remaining fuselock muskets. Shortly afterward, the bandits fire twice at the samurai within five seconds with their last firearm. A fuselock takes as much as two minutes to reload, prime, and fire.

Starring: Toshiro Mifune, Takashi Shimura, Keiko Tsushima, Yukiko Shimazaki
Revealing mistake: When Kikuchiyo tricks and kills the gunner, he chases him a short way, then stabs him with a sword. Even though there's a tree blocking the action, you can still see he never actually stabs him, he just lightly stabs the ground near him.
Kikuchiyo: This baby... It's me... It's what happened to me.
Trivia: Right after the battle scene where Kambei kills a bandit with a high stance strike, there's a shot of a bandit being swamped by peasant militia. Pay attention to another bandit riding up into this shot in the upper left corner. There's an unsuspecting extra who is standing right in the path of the second bandit's horse. The horse rams the extra, violently throwing him to the ground. (02:46:40)
