(Le Corbeau) During the Occupation, Henri-Georges Clouzot (Diabolique, Wages of Fear) filmed this disturbing probe into the group psychology of terror, couching it (as he always would) within the framework of an excellently mounted thriller. The story of Le Corbeau deals with the effects on a small town of an outbreak of poison pen letters from a source unknown to the inhabitants, or to the audience. As Clouzot establishes viable guilt in character after character, and tensions among the recipients of the letters begin to result in suicides, the mood of all-embracing suspicion is marvelously developed in visual terms as well. Based on a celebrated true story from before the war (the Tulle letters case), the tale was filmed again in 1951 as The 13th Letter by Otto Preminger.
