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。
