Ben Burtt demonstrates how he made Wall-E

"Ben Burtt demonstrates how he made Wall-E come to life and answers a ton of questions. This was a presentation I attended at Pixar and it’s seriously amazing to watch Ben as he demos how he made all the Wall-E sounds and what he bought on eBay to get new sounds. If you’re a fan of Wall-E and Star Wars, I really recommend watching some of this."
