Faking flatulence in the movies is an art. A real-life stinker toots out of the human bottom with a pitch, a dimension, a viscosity, and a soul. If you want the breakage of wind to ring true, like the creative forces behind Swiss Army Man did, then you hire ears tuned in to the finer parts of farting. Steve Nelson, the movie's on-set sound mixer, and Brent Kiser, the supervising sound editor, have those ears.
Swiss Army Man stars Paul Dano as Hank, an emotionally shattered man preparing to off himself on a deserted island. But before he can jump, Hank discovers the dead body of Manny (Daniel Radcliffe), whose active anus provides the island-dweller with a jet-powered escape. The mainland is where the pair's real adventure begins. Manny's spring-loaded body becomes Hank's survival tool. His naïveté, courtesy of a reanimated consciousness, guides Hank's spirits. Awakening, and more farts, follow.
"[The movie] uses farts to address the issue of shame," says Kiser. "If you're like, 'Well, you shouldn't feel shame that you're gay,' that carries so much context. There's emotional weight and context to that that somebody will understand. But farts are so universal and just so harmless that you can actually really address a huge, deeper issue through the thing."
