After a lengthy apprenticeship in bits and secondary roles, Gary Cooper was promoted to stardom in the Zane Grey western Arizona Bound. Cooper plays a character known only as The Cowboy, who rides into a small frontier town on the same day that a big gold shipment is departing. It so happens that the shipment has been targeted for robbery by two separate villains: "Trusted" driver Buck O'Hara (Jack Dougherty), and a swarthy stranger (Christian J. Frank). Even so, it is The Cowboy who is accused of the robbery, and soon our poor hero finds himself the guest of honor at a "necktie party." He escapes the mob in time to expose the crooks, recover the gold, and win the heart of the heroine (Betty Jewel). Discovered by stunt-rider Marilyn Mills, young Gary Cooper had appeared in a pivotal role in Samuel Goldwyn's production of The Winning of Barbara Worth and Paramount saw him as their answer to MGM's Tim McCoy or Columbia's Jack Holt. Cooper's contract would be shared by Goldwyn and Paramount for years to come ~ Hal Erickson, Rovi
