Tall, rugged and strong, George O'Brien was one of the most popular Western heroes of the 1930s, a consistent Top 10 box-office draw. Riding atop his trusty steed Mike, and armed only with his six-guns and a good-natured grin, the black-clad O'Brien made 16 shoot 'em-ups for RKO and this action-packed collection showcases three of his best. The Marshal of Mesa City (1939): A retired lawman (O'Brien) attempts to clean up a town run by a corrupt sheriff and his gun-crazy gang. Legion of the Lawless (1940): A lawyer (O'Brien) takes on the vigilantes that plan to seize a small town's land and sell it to the railroad. Triple Justice (1940): A rancher (O'Brien) sets out to clear his name after he's falsely accused of bank robbery and murder.
