Seven Samurai

Akira Kurosawa's original idea for the film was to make it about a day in the life of a samurai, beginning with him rising from bed, eat breakfast, go to his master's castle and ending with him making some mistake that required him to go home and kill himself to save face. Despite a good deal of research, he did not feel he had enough solid factual information to make the movie. He then pitched the idea of a film that would cover a series of five samurai battles, based on the lives of famous Japanese swordsmen. Hashimoto went off to write that script, but Kurosawa ultimately scrapped that idea as well, worrying that a film that was just "a series of climaxes" wouldn't work. Then, producer Sōjirō Motoki found, through historical research, that samurai in the "Warring States" period of Japanese history would often volunteer to stand guard at peasant villages overnight in exchange for food and lodging. Kurosawa then came across an anecdote about a village hiring samurai to protect them and decided to use that idea. Kurosawa wrote a complete dossier for each character with a speaking role. In it were details about what they wore, their favourite foods, their past history, their speaking habits, their reaction to battle and every other detail he could think of about them. No other Japanese director had ever done this before.

In the closing moments of the final battle, the bandits fire two musket shots only seconds apart. It is clear from the plot that at that time they possess only one musket. The black powder muskets of the age required much more time to reload. This error was pointed out in the commentary of the deluxe DVD edition.

The film's original Japanese release version runs 207 minutes, plus intermission, which includes four minutes of entr'acte music against a blank screen. This is the version that has been generally shown worldwide since the 1980s, though sometimes it is shown without the intermission and entr'acte, resulting in a listed running time of 203 minutes. The initial U.S.A. release was re-titled 'The Magnificent Seven' and released November 1956, with English subtitles, and ran 158 minutes. Some European releases were even further shortened to 141 minutes. Landmark Films re-released the film in the U.S. in December 1982, the first time outside Japan the film saw a major release with its running time intact (although the intermission and entr'acte were removed). Later U.S.A. releases by Avco-Embassy Pictures, Janus Films, and Films Incorporated, and by BFI in the UK, are also the full original version of the film.
