Trivia: At the end of the film when the Stranger (Clint Eastwood) is riding out of Lago, he passes a midget who is painting a name on a tombstone. In the next shot you see two more tombstones to the left. The names on these are "Sergio Leone" and "Don Siegel."
Trivia: Yul Brynner, The Man in Black, has only 9 lines of dialogue throughout the movie, only 32 words. In the first saloon scene, Brynner intentionally bumps Richard Benjamin and says, "Sloppy with your drink"; after some silence, Brynner says to the bartender, "Get this boy a bib"; a few moments later, Brynner taunts again, "He needs his momma"; Benjamin finally summons the courage to speak, and Brynner replies, "You say something, boy?" Benjamin says Brynner talks too much, and Brynner challenges, "Why don't you make me shut up?" Whereupon, the two men square off for a duel, and Brynner finally says, "Your move." Later, about half-way through the film, when the Man in Black invades their hotel room, Richard Benjamin overhears Yul Brynner say the line "Not a word" to James Brolin. Even later, Brynner challenges Benjamin and Brolin in the street: Brynner first says, "Hold it," and shoots Brolin dead; Brynner then smiles at Benjamin and says, "Draw."
