49th Parallel is a 1941 British war drama film; it was the third film made by the British writer-director team of Michael Powell and Emeric Pressburger. It was released in the United States as The Invaders. Despite the title, no scene in the film is set at the 49th parallel, which forms much of the Canada–United States border. The only border scene is at Niagara Falls, which is located farther south.
