For more than seventy years now, filmmakers have been using and reusing a particular scream. Without a doubt, this is Hollywood’s most famous sound effect. Many people even know it by name. But despite how widely-known this sound is, lots of people still don’t know its surprising origin story. To set the record straight, we’ve remixed one of our classic, early episodes. Featuring Steve Lee, sound designer, film historian, and creator of the Hollywood Sound Museum. Watch our video shorts on Youtube, Instagram, and TikTok. Follow us on Reddit, Twitter, and Facebook.
