Ministry of Fear

During the war years, there were quite a few propaganda films--particularly ones about Nazi spies. While many of them become pretty difficult to distinguish from the others, this one stands out as a well made and effective film that will hold your interest.

Ray Milland plays a man who had been hospitalized for psychiatric problems. When he stumbles upon a Nazi spy ring, no one believes him despite his best efforts. So, after receiving no help, he is forced to take matters into his own hands for the good of the free world.

The acting and writing are first rate and the film doesn't get mired down in clichés. By the way, Alan Napier ("Alfred the Butler" from BATMAN) plays one of the baddies!
