Geheimnis der Nacht
Director: Alfred Hitchcock
This perfunctory German version of Murder, filmed at the same time on the same sets but with a mostly different cast, is 28 minutes shorter than the English version! It leaves out all of the touches that make the English version enjoyable, and also leaves out some of the clues that lead to the murderer.
One can hardly believe Hitchcock himself directed this totally lacking, colorless run-through of his delightful MURDER. You may never get a chance to see this one, which may frustrate Hitchcock completists, but, really, there's absolutely no reason to see it, even if you only understand German! See Murder a second time instead.
