From the very beginning film was shot on 35 mm wide material. One reel contained negative film for about ten minutes, then the operator had to change the reel. Until today we divide a movie into 3, 6 or whatever reels. The material was nitrate film, not safe, very inflammable und not durable. So it is a small miracle, that only two out of the 106 films of Laurel & Hardy are considered lost, but the search goes on. When Warner Brothers came with "The Jazz Singer" in the cinemas, sound turned the film industry unside down. Laurel & Hardy had no problem with sound, but a problem with the demanding foreign countries. Dubbing was still a problem, so they got - like many other filmstars - a language teacher, memorized their dialogue and shot half a dozen sound shorts and one feature after they finished the english version in different languages, movies exist in French, Spanish, German and even Italian. We show in the museum a trailer from "Pardon us", Stan und Ollie sprechen deutsch.
