....back in the late 1960s when the book came out John Wayne read it and immediately bought the screen rights...he had been in the movie business long enough to know a good western when he saw one....and he knew this was going to be his baby all the way....at his age and with his experiance in the genre, there has never been an actor more perfect for a role.
Wayne was crushed, had to go to Wallis and plead with him to do the role of Rooster Cogburn.
John Wayne read a book?
