As I explained here hundreds of years ago, when Stan Laurel and Oliver Hardy made their early "talkies," they made some of them several times. They'd shoot the version we got here in America and then they'd go back into the same sets and costumes and bring in a (mostly) new supporting cast and shoot the dialogue scenes in German, French and/or Italian for the foreign market. Stan and Ollie didn't speak those languages but a dialogue coach would teach them how to pronounce the words, which would be written out on a blackboard out of camera range. So in the clip we have for you today, you hear the actual voices of Laurel and Hardy speaking, in this case, German.
Later on, the technology for dubbing became better and the films were translated that way for the foreign market. But we still have some interesting remnants like this trailer for the German release of the 1931 movie, Pardon Us.
