A Bullet for the General (Quién sabe?)

Damiano Damiani directed the 1966 Italian western A Bullet for the General, originally Quién sabe? ("Who knows?"). It is counted among the first and best-known Zapata Westerns, the spaghetti-western sub-genre set around the Mexican Revolution in which characters confronted with injustice turn into revolutionaries. Gian Maria Volonté, Lou Castel, Klaus Kinski and Martine Beswick star. In France it is known as El Chuncho and in Germany as Töte Amigo.

The story is set in Mexico during the revolutionary fighting; one source gives 1917. El Chuncho (Gian Maria Volonté) leads a gang poised between banditry and guerrilla struggle, and he and his men attack a regular army train. A young American on board, Bill Tate (Lou Castel), helps the raiders during the assault, then joins the gang and earns Chuncho's friendship. Their plan is to sell the captured weapons to General Elías's revolutionaries. But appearances deceive: Tate is in fact a counter-revolutionary hired killer. The relationship changes everything for Chuncho, who learns the hard way that a social revolution matters more than money. Andrea Checchi and Aldo Sambrell are also in the cast.

Franco Solinas and Salvatore Laurani wrote the screenplay, Luis Bacalov composed the music (Ennio Morricone is credited as supervisor) and Bianco Manini produced. It runs about 118 minutes.
