The trick is how much of the backstory is true. Disney told us at D23 in 2011 they found a box in the archives that had all sorts of odd stuff like a type of Laser Disc that had a cartoon of the great energy leaders Einstein, Tesla, etc, as well as all sorts of other odd stuff. For a company that took comprehensive records and maintained them the fact that this was in a box with two other labels over it was odd so they decided to make a movie over what it all may have been about.
