Movie: Sanjuro (Japan, 1962)
Scene: The Final Samurai Showdown
Aspect Ratio: 2.35 : 1
Sanjuro is a 1962 black-and-white Japanese film directed by Akira Kurosawa and starring Toshiro Mifune. It is a sequel to Kurosawa's 1961 Yojimbo.
The blood fountain in this scene became iconic almost immediately, and after that, it wasn’t possible to release a Samurai movie without fountains of fake blood spraying everywhere.
The scene is also mentioned in the book Alex Cox's Introduction to Film as an example of a composition that takes full advantage of the aspect ratio.
