John Ford

 John Ford liked to bully actors on the set, and "Stagecoach" (1939) was no exception. At one point, he said to Andy Devine, "You big tub of lard. I don't know why the hell I'm using you in this picture." Undaunted, Devine replied, "Because Ward Bond can't drive six horses." Likewise, he attacked Thomas Mitchell, who eventually retorted, "Just remember: I saw [Ford's earlier film] 'Mary of Scotland' (1936)," effectively humbling the director.

Worst of all was Ford's treatment of John Wayne. He called him a "big oaf" and a "dumb bastard" and continually criticized his line delivery and manner of walking, even how he washed his face on camera. However, at least part of this was to provoke the actor into giving a stronger performance. Claire Trevor recalls how Ford grabbed Duke by the chin and shook him. "Why are you moving your mouth so much?" he said. "Don't you know you don't act with your mouth in pictures? You act with your eyes." Wayne tolerated the rough treatment and rose to the challenge, reaching a new plateau as an actor. Ford helped cement the impression that Wayne makes in the film by giving him plenty of expressive reaction shots throughout the picture.

Stunt coordinator Yakima Canutt explained how the stunt was accomplished where, as an Apache warrior attacking the stagecoach, he is "shot," falls off his horse, and then gets dragged underneath the stagecoach: "You have to run the horses fast, so they'll run straight. If they run slow, they move around a lot. When you turn loose to go under the coach, you've got to bring your arms over your chest and stomach. You've got to hold your elbows close to your body, or that front axle will knock them off." After the stunt was completed, Canutt ran to Ford to make sure they got the stunt on film. Ford replied that even if they hadn't, "I'll never shoot that again."

Asked why, in the climactic chase scene, the Indians didn't simply shoot the horses to stop the stagecoach, Ford replied, "Because that would have been the end of the movie." In addition, Apaches would have stolen the stagecoach horses rather than killed them because, in their culture, horses were valuable in calculating a warrior's worth.
