While the dubbing in various languages is competent for accessibility, the English audio track is essential for appreciating the film's sonic landscape. Heat is a film that speaks in the language of the city—distant sirens, the hum of LAX airplanes, and the deafening roar of gunfire. The sound design is dynamic and aggressive. The famous bank robbery scene, followed by the street shootout, is a benchmark for surround sound mixing. The echo of gunfire bouncing off the downtown Los Angeles skyscrapers creates a terrifying sense of space.
