The line comes from Star Wars, spoken by Alec Guinness as Obi-Wan Kenobi in the original 1977 film, later titled A New Hope, when he senses the destruction of Alderaan by the Death Star. It has long been quoted by fans as shorthand for sensing disaster before it is confirmed, and the isolated audio clip circulates as a reaction sound for edits, memes and dramatic reveals. Its quiet, serious delivery keeps it useful whenever a creator wants foreboding without a jump scare or a punchline.
