"Back to Neverland" is a short film that featured legendary newscaster Walter Cronkite and Robin Williams that took audiences on a tour through the different stages of hand-drawn animation. It even features Williams being turned into an animated character, one of the Lost Boys from Peter Pan. The film was a part of an attraction at Disney MGM Studios called "The Magic of Disney Animation." It was made in 1989, two years before Williams would star in the live-action Peter Pan sequel, Hook. I've never seen this before and it's really entertaining so I'm sure you'll enjoy it! Thanks to /Film.
