Fortunately for Walter, he discovered at an early age that he had a gift for sound recording, even though he didn't take his youthful experiments seriously until after he had explored other paths, including architecture and oceanography. Always eager to push things and see what happens, he found himself in good company at USC film school, where he met George Lucas, another graduate student whom instructors identified as a troublemaker for daring to challenge cinematic conventions. Impressed by Ingmar Bergman's Seventh Seal, a film Walter saw while at USC, he had the revelation that maybe he could create something equally moving and monumental and at the same time earn a living. He had his chance as the sound designer for Francis Ford Coppola's Apocalypse Now, one of many award-winning productions with which Walter has been involved during a long and fruitful career. Known for taking risks and breaking the rules, he attributes his success to three main factors: luck, talent, and hard work. Each factor, he explains, functions like a leg of a tripod. The trick is to keep the tripod balanced, a skill he has mastered.
