In 1938, Walt Disney produced an audacious film that was several years in the making: a full-length feature film that was all cartoon! Snow White and the Seven Dwarfs set the stage for everything that would come after for Disney, both Walt and the company he founded. Everything about the production was an experiment. Lets have a little Snow White trivia.
There are several “hidden Mickeys” in Snow White (and a website that tracks them). Look at the wall behind the Queen when she rushes into her laboratory.
Snow White is the youngest Disney princess. She’s 14 years old.
During the making of Snow White, Walt Disney paid his staff five dollars for each successful “gag” that could be used in the film. One example is Ward Kimball’s idea that the dwarfs’ noses should pop one by one over the foot boards while peeking at Snow White.
