Caught some of the John Wayne festival on AMC over the weekend. Anyone ever notice that El Dorado and Rio Bravo are the same movie with different actors. In El Dorado, James Cann (Mississippi) plays the Ricky Nelson (Colorado) part. Arthur Hunnicutt plays the 'old coot hanging around the jail" ,Walter Brennan, part and Robert Mitchum plays the Dean Martin alcoholic sheriff part. John Wayne, of course, plays the John Wayne part. Wonder if they used the same script with changes penciled in.
