The clip comes from Star Wars: A New Hope from 1977, during the duel aboard the Death Star when Darth Vader strikes down Obi-Wan Kenobi and Luke, watching from a distance, screams in horror. The moment became one of the most quoted deaths in the original trilogy, and the isolated cry circulated widely as a reaction sound in edits, memes and fan videos. It endures because it is instantly recognisable even without the film around it, giving creators a shorthand for grief, shock and sudden loss in just two seconds.
