The amazing story behind the sounds of Star Wars: Episode IV

In this wonderful video, Ben Burtt, sound designer for Star Wars: Episode IV - A New Hope, reveals the secrets behind the fantastic zaps, beeps, and growls in that first film in the series. His first task was to figure out Chewbacca's voice that, ultimately, came from a pet bear on a farm in Tehachapi, California.

Also, I distinctly remember when I was a kid hearing for the first time that Burt discovered the blaster sound during a hike when he accidentally banged his backpack on a guy-wire anchoring a radio tower. After I learned that, I hammered on any guy-wire I came across for at least a week.
