- The film is the third collaboration between the veteran hero of the screenwriting world, Shinobu Hashimoto and Akira Kurosawa after the movie "Survival".
- In 1960, Kurosawa Akira's "Seven Samurai" was remade by John Sturges and named "Seven Noble Men". James Cowburn plays the flying knife cowboy, and the characters are directly drawn from the samurai swordsman of Akira Kurosawa.
- Due to a budget error in film shooting funds, Kurosawa had to find a new source of income. One of the options was to shoot a set of Japanese whiskey commercials. The shooting location was near his residence in Japan. He personally directed and played a guest role in it.
- "Seven Samurai" is the most expensive film shot by Toho Cinemas because the shooting time was four times the original plan. Kurosawa and his crew managed to complete the film, but Toho Cinema was on the verge of bankruptcy.

[on taking Katsushiro as a student]
Kambei Shimada: You embarrass me. You're overestimating me. Listen, I'm not a man with any special skill, but I've had plenty of experience in battles; losing battles, all of them. In short, that's all I am. Drop such an idea for your own good.
Katsushiro: No Sir, my decision has been made. I'll follow you sir.
Kambei Shimada: I forbid it. I can't afford to take a kid with me.

[Kambei is considering the farmer's offer]
Kambei Shimada: It's impossible.
Katsushiro: Sir! Why not arm them with...?
Kambei Shimada: I thought of that, too.
Katsushiro: But sir.
Kambei Shimada: [pointedly] This would not be a game. A band of forty bandits! Two or three "samurai" could accomplish nothing. Defense is harder than offense. Mountains in the back of the village?
Rikichi: Yes!
Kambei Shimada: Can horses get over them?
Rikichi: Yes!
Kambei Shimada: Fields in front. The village is wide open to horsemen... until the fields are flooded. One guard for each direction takes four. Two more as a reserve. You'll need at least... seven, including me.
