El Dorado opens with a montage of paintings by celebrated Western artists Olaf Weighorst. These beautiful pictures in many ways reflect the nature of the movie, depicting a stylised representation of the Old West that despite its beauty, never really existed. Director Howard Hawks includes every possible genre trope and meme into El Dorado but far from being a handicap, it makes the movie a perfect distillation of Hollywood Western. The pairing of John Wayne and Robert Mitchum is sublime as the two effortlessly riff off each other. If you need an example of how the Western is the most flexible and accessible movie genre, then El Dorado is a text book example.
