Trivia: El Dorado is actually part of a remake trilogy by the same director, Howard Hawks. The first was 'Rio Bravo' (1959); 'El Dorado' was next in 1967; and the final variation was 'Rio Lobo' in 1970. El Dorado is the only humorous (and by many critics acclaimed as the best) version of the three.
Trivia: In the scene near the end of the film where Mississippi, JP, and Bull are attempting to sneak into the saloon through the back, Mississippi disables the guard at the back door by disguising himself as a Chinese person. In the original release of the film, he puts on the disguise, then squints his eyes and speaks in vaguely Asian-sounding gibberish. This was deemed insensitive and inappropriate, and when the film is shown on television, the scene cuts awkwardly to avoid the offensive expressions and dialog.Jason Hoffman
