My boys! (spoiler)
Once again IMDB ignored my addition to "trivia" - but this speaks for itself. I wonder why IMDB acts the way they do when something is simple to confirm....
Anyway, at the end of the big gunfight between the Cleggs and Travis and Sandy, Uncle Shiloh is heard to exclaim: "My boys, you've killed my boys!" This is the same line that was uttered 4 years before By Walter Brennan as old man Clanton at the end of the big gunfight in "My Darling Clementine", also directed by Ford...Coincidence?
