Released a couple of months before the bombing at Pearl Harbor, this is a propaganda film aimed at rallying the world against the Nazi threat. After a disjointed start, it slowly gathers momentum and ultimately proves to be a satisfying adventure about a group of stranded Nazi soldiers surreptitiously trying to make its way across Canada. Although Howard, Olivier, and Massey get top billing, they have small roles. Olivier is a hoot as a French Canadian. Interestingly, Vaughan Williams gets above the title billing for his fine score, although it is underused. Powell, working from a script by partner Pressburger, tells the story in a stark, documentary style.
