Laurel and Hardy were really funny, even when they made sound films, but I think they were best in the silents. They made both short features and long ones. Try "Their Purple Moment" or "Two Tars" for something of greater length. There was also one (title escapes me at the moment) that involved trying to move a piano up a long flight of stairs. You wouldn't think they could make so much of that, but they did, and you keep laughing at their antics throug the whole thing.

You should look up some of the big name titles I've listed. Fritz Lang (Metropolis) and F. W. Murnau (Nosferatu) were your countrymen and their work must surely be available. Sergei Eisenstein (Potemkin) is still acclaimed as a master, and was partly of German descent.
