The Wilhelm Scream is a stock sound effect that has been used in over 400 films and television shows (and counting). It originated in 1951 in the film Distant Drums.
The Wilhelm Scream sound effect is most commonly used when someone is falling from a great height, shot, or thrown from an explosion. It’s inclusion in so many movies has become something of an inside joke for filmmakers and the audience who understand the reference.
