John Wayne] Duke hasn't any patience with anybody: his family, other
actors, anybody. If you've got a Big Name Star, he'll keep quiet.
Howard Keel on
The War Wagon (1967), I remember. One day Duke started
pushing him around, grabbing him, showing him how to play the scene.
After the scene was over, Keel said, "If he puts his hands on me again,
I'm gonna clobber that son of a bitch."
