The first “epic” western of the talkie era, The Big Trail is motivated by a hero’s search for the murderer of his father. Twenty-three-year-old John Wayne, hitherto limited to bit parts, was thrust into the difficult leading role, a young mountaineer put in charge of a huge California-bound wagon train. Over the next several months, Wayne and his fellow pioneers face every imaginable hazard and disaster, from blistering desert heat to blinding snowstorms, negotiating steep cliffs, treacherous rivers, uncharted forests and other such natural obstacles.
