Jean Jacket is the mysterious, shape-shifting creature at the centre of Jordan Peele's 2022 film Nope, where a seemingly ordinary cloud hides a predatory being that terrorises a horse ranch in California. Its unsettling vocalisations became one of the film's most memorable sound designs, distinct from a conventional animal roar. Fans and editors have since reused short roar clips like this one in horror edits, reaction videos and parodies, where the sound instantly signals a huge, unseen threat without needing any visual explanation.
