A Fistful of Dollars (Italian: Per un pugno di dollari) is a 1964 western film directed by Sergio Leone and starring Clint Eastwood alongside Gian Maria Volontè, Marianne Koch, Wolfgang Lukschy, José Calvo and Joseph Egger. Released in Italy in 1964 then in the United States in 1967, it initiated the popularity of the Spaghetti Western film genre. A Fistful of Dollars was shot in Spain, mostly near Hoyo de Manzanares close to Madrid, but also (like its two sequels) in the Cabo de Gata-Níjar Natural Park in Almería province.
The film's music was written by Ennio Morricone, credited as Dan Savio. Morricone recalled Leone requesting him to write "Dimitri Tiomkin music" for the film. The trumpet theme is similar to Tiomkin's El Degüello theme from Rio Bravo (1959) (that was called Un dollaro d'onore in Italy) while the opening title whistling music recalls Tiomkin's use of whistling in his Gunfight at the O.K. Corral (1957). "Some of the music was written before the film, which is unusual. Leone's films were made like that because he wanted the music to be an important part of it, and he often kept the scenes longer simply because he didn't want the music to end. That's why the films are so slow - because of the music." [wikipedia]
