Undercover is a British-made WWII picture glorifying the efforts of a small group of Yugoslavian resistance fighters who struggled against the Nazis. In the tradition of Hollywood, virtually all the Slavic characters are played by such doggedly British types as Tom Walls, Michael Wilding and John Clements. As was customary, the Nazi invaders are shown to be the products of an evil totalitarian regime (quite true) while the Yugoslavs are freedom-loving individuals treated with equanimity by their expansive Communist government (not quite true). After the war, it became common knowledge that many supposedly patriotic Yugoslavian partisans, notably those commandeered by General Mihajlovic, were actually pro-Nazi. As a result, films like Undercover and Hollywood's Chetniks were hastily, and without explanation, withdrawn from circulation. ~ Hal Erickson, Rovi
