[1] Skywalker Sound was founded as Sprocket Systems in San Anselmo, California.

For instance, Kentfield resident Pat Welsh was "discovered" while shopping at a camera store and went on to provide the voice for E.T.

During the sound recording of Raiders of the Lost Ark, Harrison Ford practiced his bullwhip technique in the parking lot.
