There will probably never be another stuntman who can compare to Yakima Canutt. He had been a world champion cowboy several times and where horses were concerned he could do it all. He invented all the gadgets that made stunt work easier. One of his clever devices was a step that attached to the saddle so that he had leverage to transfer to another moving object, like a wagon or a train. Another was the "shotgun," a spring-loaded device used to separate the tongue of a running wagon from the horses, thus cutting the horses loose. It also included a shock cord attached to the wagon bed, which caused wheels to cramp and turn the wagon over on the precise spot that was most advantageous for the camera.
