E.T.'s Walking Sound Was Made by Jelly

The world of filmmaking is a symphony of sights and sounds, where every rustle, thud, and whisper contributes to the immersive experience. This intricate auditory landscape is often crafted by skilled sound designers and Foley artists, whose work, though frequently unnoticed, is essential to a film's realism and emotional impact. The practice of Foley artistry, named after Universal Studios sound engineer Jack Foley in the 1930s, involves recreating everyday sound effects in synchronization with the visual elements of a film. These artists perform actions like footsteps, clothing movements, and the handling of props on specialized stages, ensuring that the sounds perfectly match the on-screen action and enhance the viewer's perception of reality.

Among the most celebrated innovators in this field is Ben Burtt, a sound designer renowned for his groundbreaking work on iconic films. Burtt pioneered an approach that often blended "found sounds" – ordinary noises recorded from the real world – with more traditional effects to create unique and memorable auditory signatures for characters and environments. His philosophy was to seek out natural sounds that could be manipulated to evoke specific feelings or characteristics, moving away from purely electronic effects that were common in science fiction before his time.

For the distinctive squishing sound of the beloved extraterrestrial's footsteps, Burtt employed a wonderfully simple yet ingenious technique. Rather than relying on complex electronics or animal sounds, he achieved the desired effect by squeezing a wet cloth filled with grape jelly. The viscous texture of the jelly, combined with the damp fabric, produced a moist, slightly rubbery squish that perfectly conveyed the alien's unique gait, making the character feel more tangible and endearing. This creative solution exemplifies how Foley artists transform the mundane into the magical, using everyday objects to craft the sonic identity of fantastical worlds.

Such imaginative sound design is a testament to the artistry involved in filmmaking, where every detail, no matter how small or seemingly insignificant, is carefully considered to draw the audience deeper into the story. The subtle, squelching steps of the alien became an integral part of its character, proving that sometimes, the most extraordinary effects can spring from the most unexpected, and even delicious, sources.
