Query: A Hollywood Western

Rio Bravo had the potential to be a great western, but the studio moguls had other ideas...like making money at the box office. What else could justify the casting of lightweights Dean Martin and Ricky Nelson? I suppose with the breakup, Jerry Lewis wasn't available to play Colorado. The song near the end of the film didn't help matters either. How could John Wayne criticize High Noon and then make this kind of fluff? This is not The Searchers (perhaps the definitive John Wayne film), but even as a light hearted western, it's about two hours too long. The Duke has the sissy walk down and Angie Dickinson is not hard to look at, but Walter Brennan is the only gem in this clinker.
