Have you ever seen foley artists? Probably not, because their job is to remain invisible and create a sense of reality within a movie using only sound. Foley artists recreate ambient sounds in a studio, and these reproduced sounds can be anything from footsteps to the swishing of clothing. Filmmaker Daniel Jewel has created an insightful documentary, called ‘The Secret World of Foley‘ which presents the backstage of foley art. Without these crucial background noises, movies feel unnaturally quiet and uncomfortable.
