The importance of sound in a movie

The movie "Deer Hunter" took six months to shoot, and a further five months to mix the soundtrack. Since this was his first Dolby film, Michael Cimino was eager to exploit the technology to its fullest potential. A short battle sequence, for example, (200 feet of film) took five days to dub. For the re-creation of the American evacuation of Saigon, he accompanied composer Stanley Myers to the location and had him listen to the sounds of vehicles, tanks, and jeep horns as the sequence was being filmed. Myers then composed music for the sequence in the same key as the horns, so that it would blend with the images creating one truly bleak experience.
