The Big Trail is a 1930 American pre-Code early widescreen movie shot on location across the American West starring John Wayne in his first leading role and directed by Raoul Walsh. In 2006, the United States Library of Congress deemed this film "culturally, historically, or aesthetically significant", and selected it for preservation in the National Film Registry, saying "the plot of a trek along the Oregon Trail is aided immensely by the majestic sweep provided by the experimental Grandeur wide-screen process used in filming".
