A little tidbit related to horsemanship. Randolph Scott was in the Army field artillery during WWI in France. He learned to ride horses and shoot in the Army which he used extensively in his later years acting.
Now here's a Hollywood actor who could RIDE.....Ben Johnson. He went from being a horse trainer/stuntman to an actor, and then he took time off to do a rodeo tour and won the WORLD ROPING CHAMPIONSHIP in 1953.
