Watching this stylish and nightmarish black and white movie was a great delight. I am really glad someone brings these hidden treasures to the light. The main subject of the story is the question whether the main character - a truly great performance by Jeffrey Hunter - is insane or not. The cinematography and the set design pull the viewer down into the same state of confusion as the main character. We share his insecurity as life seems to play tricks on him and everybody seems to be opposed to his view of events. Very interesting is the stark contrast between the ultra modern industrial complex in which the main character works and the Gothic interior of the residence of the owner of that corporation (small part but convincing under acting by film noir veteran Dana Andrews). Also great performance by Anne Francis as a kind of femme fatale - isn't she a vastly underrated actress who could have had a career like Ellen Burstyn? Anyway, after watching this I felt compelled to purchase the Honey West TV series in which Francis stars - another great delight in black and white.
