Winchester '73 is a 1950 American Western film noir directed by Anthony Mann and starring James Stewart, Shelley Winters, Dan Duryea and Stephen McNally. Written by Borden Chase and Robert L. Richards, the film is set in 1876 in a variety of famed western locations and follows the journey of a prized rifle from one ill-fated owner to another, as well as a cowboy's search for a murderous fugitive. It is the first Western film collaboration between Mann and Stewart, the first of eight films they made together, and was filmed in black and white. It was also the first film where an actor received a percentage of the receipts, a practice since known as "points", as compensation.
