Chewbacca’s voice
Another very lovable character that added comedic relief to the films and was the right-hand man to Han Solo himself. Chewbacca is a giant creature that resembles Bigfoot in many ways. We can not help but feel like that was the inspiration for the character. But there seem to be more things we did not know about him.
For example, Chewbacca’s voice is something that no one even bothered to investigate just where they get that sound. Well, it’s a combination of a bunch of animals from our own planet, then mixed together in the studio. The twist is that those are recordings of dying animal sounds, pretty morbid stuff.
