Invites to Pixar's Emeryville, California headquarters are few and far between, so when we received one at Empire Towers there was much excitement, not to mention requests for toys from the gift shop.

Arriving at the impressive facility where Finding Nemo, Monsters Inc. and Ratatouille were created — and where, even now, the resident geniuses are working hard on Wall-E, next year's Up and Toy Story 3 — we were greeted by "Pixar University Dean" Randy Nelson (a man with more enthusiasm and perkiness than your average cartoon chipmunk) and shown around the place. Fortunately, Randy agreed to do an impromptu video tour for us, so now you can see all the sights for yourself.

Watch this video to find out just why everyone in Hollywood's jealous of the lucky few who score jobs there...

Ratatouille is now available on Blu-ray and DVD.
