Set in August 1944, the film, shot in black-and-white, sets French Resistance-member Paul Labiche (Lancaster) against German Colonel Franz von Waldheim (Scofield), who is attempting to move stolen art masterpieces by train to Germany. Inspiration for the scenes of the train's interception came from the real-life events surrounding train No. 40,044 as it was seized and examined by Lt. Alexandre Rosenberg of the Free French forces outside Paris. - Wikipedia
