John Wayne

I just started reading John Wayne: The Life and Legend by Scott Eyman. It has been very favorably reviewed and I'm anticipating learning a lot about the man who said of himself:

That guy you see on the screen isn't really me. I'm Duke Morrison, and I never was and never will be a film personality like John Wayne. I know him well. I'm one of his closest students. I have to be. I make a living out of him. — Duke Morrison, AKA John Wayne, 1957 (from the book)
