Deborah Stratman’s bewitching short film Hacked Circuit, which premiered at Sundance earlier this year, presents a roving, unbroken look inside the foley post-production process at an LA studio. Along those lines, this featurette with Interstellar‘s Supervising Sound Editor and Sound Designer, Richard King, provides perspective into the blockbuster’s unusually naturalistic and practical sound effects. To capture the essence of a dust storm, King and his team built a sand gun and fired it against a rusty car; to convey a car ripping through a cornfield, they built a rig and did it for themselves. Just as Nolan eschews green screens, he refrains from the use any computer generated sound as well.
