John Wayne learned his famous walk, his swagger, and how to choreograph fight scenes from the greatest stuntman who ever lived and real life cowboy from Eastern Washington Yakima Canutt. Yak was a very good actor in his own right and was in plenty of silent westerns and doubled for Wayne many times,the most famous stunt being the scene in Stagecoach where Wayne (Canutt), is dragged under the horses.

Oh, I know about Yak. I have his book. And all his available silent films, like “Hellhounds of the Plains,” “Branded a Bandit,” “Desert Greed,” “The Iron Rider,” etc. He even lived long enough to go to several film festivals.
Although when it comes to Wayne’s “walk,” I always heard that it was character actor Paul Fix (later, Micah on “The Rifleman”) who in the early-1930s, taught Wayne that particular ‘cowboy’ gait, back when those Lone Star productions were being filmed.
