A: Even before the New York fair, in 1958, Walt Disney had produced America the Beautiful in CircleVision, to be shown at the Brussels World’s Fair. But after doing the four shows for the 1964–65 fair, Walt decided to build his park in Florida, so he had no time for outside work for world’s fairs. However, after Walt died, the Disney company did produce additional CircleVision films for fairs in Canada—Expo ’67 in Montreal and Expo ’86 in Vancouver, British Columbia.
