At once a compelling piece of anti-isolationist propaganda and a quick-witted wartime thriller,49th Parallelis a classic early work from the inimitable British filmmaking team of Michael Powell and Emeric Pressburger. When a Nazi U-boat crew, headed by the ruthless Eric Portman, is stranded in Canada during the thick of World War II, the men evade capture by hiding out in a series of rural communities, before trying to cross the border into the still-neutral United States. Both soul-stirring and delightfully entertaining,49th Parallelfeatures a colorful cast of characters played by larger-than-life actors Laurence Olivier, Raymond Massey, Anton Walbrook, and Leslie Howard.
