Oscar buzz is nothing new for Ben Burtt. Burtt won his first Oscar in 1978 for his work on the original “Star Wars” — he created the creature and droid voices — and his second in 1981 for “Raiders of the Lost Ark.” He has nine nominations in total.

But “Wall-E,” he says, was more challenging than any of them.

He stared working on the pic three years ago, and he needed almost every minute.

“On an Indiana Jones film, which is a big movie, I made about 700 new sounds,” he reports. “On ‘Star Wars,’ I made probably about 1,000 sounds per movie. ‘Wall-E’ had over 2,600 sounds, and it’s only 90 minutes long!”

After 30 years in the business, Burtt is still excited to add a sound to films like “Wall-E.”

“I would often drive home saying, ‘This is truly an unusual job.’ There are not many people who get to play a robot (in a film),” he says. “Nonetheless, I’ve thrived in that field and I’m thankful for that.”
