We’ve all heard it. It’s in Star Wars, Raiders of The Lost Ark, and even in A Star is Born with Judy Garland. It was originally recorded by an unknown performer for a 1951 Gary Cooper film called Distant Drums, and has been used countless times in horror, action, comedy, animated, science fiction and even musical films.  It’s a scream.  And the scream is known in the industry as “The Wilhelm.”
