I recently discovered that R2D2 and Wall-E share the same voice because the guy who created the sound effects for Star Wars is Ben Burtt who also created Wall-E's voice and I think it is so cool. It's hard to believe that many people consider Ben Burtt the father of modern sound effects for movies today
