Although it is common practice nowadays, this was the first film to feature a fight sequence in which two samurai swung their swords down as they passed each other and then suddenly stopped moving as one of them collapsed to the ground and died, and the film also used sound effects to accompany the action in swordfights.
今ではよく見られる演出だが、侍同士の対決シーンで、すれ違いざま刀を振り下ろし、いったん静止して片方が倒れて死ぬという描写や、効果音として刀の斬殺音を使用したのは、本作が最初である。
