Who did the most of the stunts for John Wayne in the 1965 movie, The Sons of Katie Elder?
This picture marked the return of John Wayne to work after having a cancerous lung and two ribs removed just four months earlier. He insisted on doing all his own stunts to show the public that the illness hadn't slowed him down.
When John Wayne is dragged into the river, you can hear a child calling out, "Dad!". This was his three-year-old son Ethan Wayne, who was watching off camera and knew how ill his father was. Wayne nearly contracted pneumonia from filming this scene.
