Canutt and Wayne pioneered stunt and screen fighting techniques still in use. Much of Wayne's on-screen persona was copied from Canutt. The characterizations associated with Wayne - the drawling, hesitant speech and the hip-rolling walk - were pure Canutt. Said Wayne, "I spent weeks studying the way Yakima Canutt walked and talked. He was a real cowhand." In 1934 the two appeared together in the western Randy Rides Alone in which Wayne starred and Canutt appeared as "henchman Spike."
In 1934, Herbert J. Yates of Consolidated Film Industries combined Monogram, Mascot, Liberty, Majestic, Chesterfield, and Invincible Pictures to form Republic Pictures, and Canutt became Republic's top stuntman. He handled all the action on many pictures, including Gene Autry films; and several series and serials, such as The Lone Ranger and Zorro. For Zorro Rides Again, Canutt did almost all the scenes in which Zorro wore a mask, and he was on the screen as much as the star John Carroll. When the action was indicated in a Republic script, it said "see Yakima Canutt for action sequences."
