49th Parallel

This British-propaganda film from Michael Powell and Emeric Pressburger presents the Battle of the Atlantic in World War II as an imminent threat to the United States. In the early days of World War II, a German U-boat is sunk in Canada's Hudson Bay. Hoping to evade capture, a small band of German soldiers led by commanding officer Lieutenant Hirth (Eric Portman) attempts to cross the border into the United States, which has not yet entered the war and is officially neutral in 1941. Along the way, the German soldiers encounter brave men such as French-Canadian fur trapper Johnnie (Laurence Olivier) and soldier Andy Brock (Raymond Massey).
