Today it's Yul Brynner as he was in the Magnificent Seven. There is a great story out there about how Steve McQueen taught Yul how to draw and hold a gun. Story is that basically McQueen was messing with him and Yul thought he was serious. Watch the movie, when Yul pulls his weapon it just looks goofy. Trouble is no one ever told Yul it was a joke.
He did it again in Westworld.
I bet Steve is still messing with Yul somewhere.
