Tanz der Skelette (1929)

Originaltitel: The Skeleton Dance

The greatest talking picture novelty ever screened! -- A laugh riot from start to finish! A comically clever cartoon classic with music, sound, and original effects

The clock strikes midnight, the bats fly from the belfry, a dog howls at the full moon, and two black cats fight in the cemetery: a perfect time for four skeletons to come out and dance a bit.
