The Sound Of The Lightsaber
One of the things that made the movie truly iconic is the lightsabers. But did you know that lightsabers were supposed to not make any sound at all? According to George Lucas, the idea of creating a lightsaber was brought up in order to have a legendary weapon that will complement the storyline of the original trilogy.
Despite the setting being in old space-age time, they needed the lightsaber to be futuristic in a way. Thus, the idea for the lightsaber being a laser sword was solidified, with its sound being a combination of the hum of idling interlock motors in aged movie projectors and interference caused by a television set on a shieldless microphone. And voila, one of the most iconic weapons of all time was created.
