"While George was still working on the screenplay for the first film, we decided that sound was going to be an important part of Star Wars. So I went down to the
USC cinema department, where George and I went to film school, and asked the head of sound if he had any finishing students who were particularly creative.
He gave me
Ben Burtt, who became our
sound designer. Ben worked for over a year collecting noises from all kinds of unusual sources, and we'd meet to listen and chat about them. By the time we finished shooting he had an enormous collection of sounds, which we used for everything from
R2-D2's bleeps to the laser effect created when the space ships fire at each other."
