Western films have long served as inspiration in the course of film history. Orson Welles reportedly watched John Ford’s film Stagecoach repeatedly while preparing and editing Citizen Kane. Akira Kurosawa was said to have worshiped the work of John Ford and applied the Japanese sensibilities of samurai to a uniquely western genre of storytelling. Kurosawa made epic western-like films like Seven Samurai, Yojimbo, and Sanjuro.
One of his films in particular, Yojimbo, inspired one of the most influential directors of westerns, Sergio Leone. Leone turned Yojimbo, a samurai film inspired by westerns, into an Italian-made “spaghetti western” called A Fistful of Dollars. Seriously, it’s a direct remake with many of the same shots and lines directly paying homage.
