The Great Train Robbery is a 1903 American silent Western action film made by Edwin S. Porter for the Edison Manufacturing Company. It follows a gang of outlaws who hold up and rob a steam train at a station in the American West, flee across mountainous terrain, and are finally defeated by a posse of locals. The short film draws on many sources, including a robust existing tradition of Western films, recent European innovations in film technique, the play of the same name by Scott Marble, the popularity of train-themed films, and possibly real-life incidents involving outlaws such as Butch Cassidy.
Porter supervised and photographed the film in New York and New Jersey in November 1903; the Edison studio began selling it to vaudeville houses and other venues in the following month. The cast included Justus D. Barnes and G. M. Anderson, who may have also helped with planning and staging. Porter's storytelling approach, though not particularly innovative or unusual for 1903, allowed him to include many popular techniques of the time, including scenes staged in wide shots, a matte effect, and an attempt to indicate simultaneous action across multiple scenes. Camera pans, location shooting, and moments of violent action helped give The Great Train Robbery a sense of rough-edged immediacy. A special close-up shot, which was unconnected to the story and could either begin or end the film depending on the projectionist's whim, showed Barnes, as the outlaw leader, firing his gun directly into the camera.
