Desperate Journey is a 1942 American World War II action and aviation film directed by Raoul Walsh and starring Errol Flynn and Ronald Reagan. The supporting cast includes Raymond Massey, Alan Hale Sr., and Arthur Kennedy. The melodramatic film featured a group of downed Allied airmen making their way out of the Third Reich, often with their fists.

49th Parallel is a 1941 British war drama film. It was the third film made by the British filmmaking team of Michael Powell and Emeric Pressburger. It was released in the United States as The Invaders. The British Ministry of Information approached Michael Powell to make a propaganda film for them, suggesting he make "a film about mine-sweeping". Instead, Powell decided to make a film to help sway opinion in the then-neutral United States. Said Powell, "I hoped it might scare the pants off the Americans" and thus bring them into the war. Screenwriter Emeric Pressburger remarked, "Goebbels considered himself an expert on propaganda, but I thought I'd show him a thing or two". Powell persuaded the British and Canadian governments and started location filming in 1940, but by the time the film appeared, in March 1942, the United States, which had been trying to stay out of the war in Europe, had been drawn into taking sides against Germany after being attacked three months earlier.
