Here’s a wonderful glimpse into the animation techniques that were pioneering at the time of Disney’s first feature-length animation, ‘Snow White and the Seven Dwarfs.’ You get to see some shots of Snow White being drawn and photographed, sound effects being recorded, and people arriving at the premiere. You also get a good dose of the Disney sexism in which all women who work on a film are referred to as ‘pretty girls.’ It’s basically an advertisement for the film, but it’s a good one.
