The Train

The Train is a 1964 action war film directed by John Frankenheimer and starring Burt Lancaster, Paul Scofield and Jeanne Moreau. The picture's screenplay—written by Franklin Coen, Frank Davis, and Walter Bernstein—is loosely based on the non-fiction book Le front de l'art by Rose Valland, who documented the works of art placed in storage that had been looted by Nazi Germany from museums and private art collections. Arthur Penn was The Train's original director but was replaced by Frankenheimer three days after filming had begun.
