There used to be something similar in a movie at Disneyland about how they made Great Moments with Mr. Lincoln. It used to freak me out as a kid.
I saw the animatronic Presidents in Walt Disneyworld, sure they were astonishing but like everything else there is outdated. It was kinda sad going to both the Disney parks in America just to see outdated tech from 20 years or more.
However I bet the Tokyo Disney park is cutting edge.
