For anyone interested in motion picture sound design or creation of SFX. Check out the extras on the newly released Wall-e DVD. There's an excellent bio about 20 minutes long about Ben Burtt and the creation of the sound effects for the movie. Which in the case of this movie means 99% of the audio for the whole film. Wall-e's voice is actually Ben himself. It's got some great footage of old Disney sound effects creation as well. Well worth a look... and the movie's great too!
