You know the sound effect, now check out the story behind the Wilhelm Scream.

A TikToker alleged that workers played “male screaming sound effects” while she was the only customer in a restaurant, and viewers think that was their way of getting her to leave.

The Wilhelm Scream sound effect has been heard in everything from 'Star Wars' to 'Avatar.' But why do so many filmmakers use it?

CalArts Professor Craig Smith discovered the original recording session of the now-famous "Wilhelm scream" while preserving an archive of old sound effects.

Favreau, challenging his audience to a sound hunt, later tweeted, ‘The Wilhelm Scream was used in Iron Man 1. Anyone know where?’ Feel free to leave a comment here if you know the answer.

While researching sound effect libraries, Burtt found that the scream had already been recorded for a different 1951 western film by actor and singer Sheb Wooley.

The Wilhelm Scream is one of the most famous sound effects in film history. It's been used in over 100 Hollywood movies and became an inside trope.
