Menaces (Threats) was originally filmed in 1938 under the title Cinq Jours d'Angoise. Thanks to a studio fire, the release of the film was held up for nearly two years, by which time its "rumors of war" subtext had taken on a new topicality. John Loder and Mireille Balin star as, respectively, a British newspaperman and his French fiancee. During the Munich crisis, Loder and Balin decide to take refuge in a Parisian hotel until they're certain that war will not break out. The other hotel guests include Austrian professor Erich von Stroheim, whose hopes of becoming a French citizen are dashed by the growing animosity against all things Teutonic. Though Von Stroheim's fate is a tragic one, Loder and Balin manage to weather the crisis and find lasting happiness.
