Wellman and starring Henry Fonda, Dana Andrews and Mary Beth Hughes, and featuring Anthony Quinn, William Eythe, Harry Morgan and Jane Darwell. Two drifters are passing through a Western town, when news comes in that a local farmer has been murdered and his cattle stolen. The townspeople, joined by the drifters, form a posse to catch the perpetrators. They find three men in possession of the cattle, and are determined to see justice done on the spot.
The film premiered in May 1943 to positive reviews from critics. It was nominated for the Academy Award for Best Picture at the 16th Academy Awards, losing to Casablanca.
In 1998, the film was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant." The film was adapted from the 1940 novel of the same name, written by Walter Van Tilburg Clark.
