Spine 30: M

Fritz Lang's M (1931) is the German directors first film with sound and star Peter Lorre's first film and first villainous role. Technology and star are both put to excellent use. M is also a film that the Nazi's tried to suppress before they were even in power. I can't think of a more glowing recommendation, but I will say that has always been one of my favorite films since I first saw it many, many years ago.
