Watch soap2day. What goes in to the phrase, "Let's go to the movies"? An off-screen narrator takes us back to the earliest days of film: clips remind us of early stars and blockbusters. He explains how sound came to motion pictures: we see Jolson singing "Mammy" and John Barrymore playing Richard III. Next is a salute to the 30,000 people working in Hollywood at 272 different crafts. A montage shows us some of those jobs. It ends with a look at the physical production of celluloid (cotton and silver) and the many aspects of movie making. The narrator promises more short films about each step in production. Preserved by the Academy Film Archive in 2012.
