Just found this show on YouTube called "Disneyland Goes to the World's Fair". It was made before the 1964 World's Fair in New York, hosted by Walt himself. He first goes over the history of world's fairs, a little part about Disneyland's Audio-Animatronics, and then goes in-depth about the attractions that Imaginerring put together for the World's Fair, which include Carosel of Progress, Its a Small World, Great Moments with Mr. Lincoln, and what is now Primeval World. I'd never seen this before and its fun to see Walt talk so passionately about his creations and directing his projects.
