Blood for a Silver Dollar (Italian: Un dollaro bucato), also known as One Silver Dollar, is a 1965 Italian-French Spaghetti Western film directed by Giorgio Ferroni, written by Giorgio Stegani and Ferroni and starring Giuliano Gemma and Ida Galli.
Upon release in the United States, nearly all of the cast members and production team had their names changed for the English audience. In France the film is known as Le Dollar troué. Gemma was billed as "Montgomery Wood" as with many of his other films. The title song had a successful cover version by Nini Rosso.
The original title music, composed by Gianni Ferrio, was used in Quentin Tarantino's Inglourious Basterds soundtrack. Some of Ferrio's remaining themes are also featured in the videogame Red Dead Revolver.
