Legacy
* A Playstation 2 game called Seven Samurai 20XX is based on the film. Its setting is a poor, dystopian future. Most of the characters' names are taken directly from the film.
* In 2004, Kurosawa's estate approved the production of an anime remake of the film, called Samurai 7. The animated series, which alters some elements of the tale (changing Kikuchiyo into a steam-powered robot, a side-story involving merchants), was released in Japan and the US in 2005. In 2006, the Independent Film Channel began airing the 26 episode series.
* The Magnificent Seven and its many unrelated "sequels," Battle Beyond the Stars, and The Wild East are all remakes of The Seven Samurai set in Mexico, space, and the post-Soviet countries, respectively.
* Juzo Itami's film Tampopo has references to both this film and the Spaghetti Westerns that Kurosawa was an inspiration for.
* The Hindi Bollywood film Sholay has a similar plot, but also reflects the other films of Kurosawa.
* The film Once Upon a Time in the West has a different plot, but closely reflects the style of Kurosawa's film.
* The comedy film Three Amigos spun a twist on the plot of The Seven Samurai: the gunslinging ronin are actually professional actors who think they are being hired to pretend to save a town from bandits. The same idea was later replicated in the animated film A Bug's Life and the Star Trek spoof Galaxy Quest.
* The Seven Samurai theme has also been adopted in several novels. Stephen King's novel Wolves of the Calla, part of his Dark Tower series mimics the action of the film.
* The mystery novel Potshot by Robert B. Parker also follows this pattern. Parker's detective hero Spenser gathers a group of six tough guys (all of whom had appeared in earlier novels in the series) to defend a small Arizona community.
* "The Seven Samurai" is also used as a nickname for the seven astronomers (Alan Dressler, Sandra Faber, Donald Lynden-Bell, Roberto Terlevich, Roger Davies, Gary Wegner and David Burstein) who first postulated the existence of the Great Attractor, a huge, diffuse region of material around 250 million light years away that results in the observed motion of our local galaxies.
* In Nintendo's Advance Wars video game series, the character Kanbei is named Kikuchiyo in the Japanese versions of the games (Game Boy Wars Advance 1+2 and Famicom Wars DS).
* The Game Boy Advance game Double Dragon Advance by Atlus/Million also featured another character named after Kikuchiyo as a boss in the game's fourth level (his name is shortened to Kikucho in the English language version).
* The Deep Space Nine episode "The Magnificent Ferengi" also cites the movie.
* In Marvel comics, and more precisely in the Earth X continuity, Iron Man built seven giant robots which he called "The Seven Silver Samurai". The name pays homage to both the "Seven Samurai", and Marvel's own Silver Samurai
* In issue 39 of David Lapham's independent comic Stray Bullets, a ronin Amy Racecar (the fantastic imaginary alter-ego of the series 'main' character) meets Kikuchiyo as he is following the other six samurai and they have a brief conversation. The remainder of the issue is more a strange take on Akira Kurosawa's Yojimbo.
