The Wilhelm scream was first used in the 1951 western Distant Drums and got its name from Private Wilhelm in The Charge at Feather River in 1953. The recording, believed to be voiced by actor Sheb Wooley, sat in the Warner Bros library until sound designer Ben Burtt revived it for Star Wars in 1977. Burtt and other editors then slipped it into hundreds of films, games and shows as an inside joke, turning a stock library scream into one of cinema's most famous Easter eggs.
