Douglas Sirk was still establishing himself as director in America after fleeing German when he made this nifty bit of WWII propaganda. John Carradine chews the scenery as a sneering Nazi officer, the real-life Reinhard Heydrich, Nazi governor of Prague. This film is based upon true event, though I'm a bit dubious of the film's historical accuracy. However, dramatically the film is exciting, fast paced, and features some well drawn characters. Made on the cheap at a poverty row studio, this film was picked-up by MGM who then gave the film a much larger release. Overall, this is nowhere as great as Sirk's later films, but it is a tight and highly enjoyable little film.
