This 1944 thriller represents an epochal meeting of two masters of Catholic guilt and paranoia, novelist Graham Greene and director Fritz Lang. Ray Milland, just released from a sanitorium, finds the outside world more than a fit match for his delusions as he stumbles into an elaborate Nazi plot. The hallucinatory quality of the opening scene (an innocent country fair turns out to be a nest of spies) is reminiscent of Lang’s expressionist films of the 20s, but this is a more mature, more controlled film, Lang at his finest and purest.
