20 Things You Somehow Missed In Star Wars: Episode IV: A New Hope
2. The Familiar Sounds That Went Into Some Sidekick's Voices
And it just wouldn't be right to spend so much time talking about the various familiar sounds occupying this first-ever trip to the galaxy far, far away without shining a light on the noises made by the real stars of the show: the trusty sidekicks.
When it comes to Han Solo's loyal companion Chewbacca, Ben Burtt opted to combine a whole host of different mammals together for his many varying growls and roars, including bears, badgers, seals, lions, and moaning walruses.
And Burtt also had a rather intriguing way of bringing R2-D2's various beeps and whistles into existence, too. An ARP 2600 analog synthesiser was mixed with his own vocalisations that were processed through other effects to create the baby-like cries and sounds associated with this cheeky little astromech.
