How the West Was Won (film)

How the West Was Won is a 1962 American epic-Western film. The picture was one of the last "old-fashioned" epic films made by Metro-Goldwyn-Mayer to enjoy great success. Set between 1839 and 1889, it follows four generations of a family (starting as the Prescotts) as they move ever westward, from western New York state to the Pacific Ocean. The picture was filmed in the curved-screen three-projector Cinerama process.
