Rio Bravo is a western that's rich in characterization and great dialogue; it also doesn't lack its share of awesome shootouts. John Wayne and Dean Martin give Oscar-worthy performances. Angie Dickinson, Ricky Nelson, and Walter Brennan aren't too bad themselves. A fine film worth watching over and over again.
This is one of those movies i have to watch when I come across it on cable. Wayne and Martin have great chemistry, and Brennan adds just the right amount of humor. Wayne is basically playing Wayne by this time, but he's so #!@%*# good at it, you just have to go along.
