Es geschah am hellichten Tag

From IMDB: It gets everyone frightened and anxious! Great Movie.

Once I met an arabian, and while talking about cinema, he said, for knowing this movie he would forget five of his lovely movies, after watching it ! G. Fröbe and H. Rühmann are playing such fabulous, that you think somebody inconvenient is entering your near forest. Everybody I know is worn down after this Horror-criminal, where NO violence or anything bizarre is shown! Turn off the lights.

One of the best movies of the 1950ies.
