Without doing much research I think that the movie El Dorado had Wayne and Mitchem and was a remake (I believe) of a movie called Rio Bravo which starred Wayne, Martin and Ricky Nelson. Rio Bravo is considered by some to be one of the best westerns ever to hit the silver screen. It would easily make my top 5 list.
