The film took five months to mix the soundtrack. One short battle sequence, two hundred feet of film in the final cut, took five days to dub. Another sequence re-created the 1975 American evacuation of Saigon. Michael Cimino brought Stanley Myers out to the location to listen to the auto, tank, and Jeep horns as the sequence was being photographed. The result, according to Cimino: Myers composed the music for that scene in the same key as the horn sounds, so the music and the sound effects would blend with the images to create one jarring, desolate experience.
