The St. Petersburg Times released an article in regards to an interview with some Disney engineers and artists explaining how they created and modified their attractions including Expedition Everest.
"...making life-sized statues of Disney characters can be tricky for flat-screen cartoon characters that only recently were fleshed out for 3-D films. To get the angles of a flying Peter Pan and Wendy right, Disney sculptor Joni Van Buren used photos of her 11-year-old nephew doing a bellyflop into a ball pit at McDonald's as a guide."
Wow! That is very interesting. I love to read little facts like that! Thanks for posting!
