Dean Martin as "Dude the Drunk," eh? Why not -- it works in Rio Bravo a favorite among Western enthusiasts that nonetheless is far too long, spending too long setting up the story before getting to the powerful finale. Wayne is good, but Dean-o steals the show along with Walter Brennan's crusty jailkeeper, who owns every scene he's in. A definitive piece of Americana by way of Howard Hawks, Rio Bravo is what the late 1950s studio system was all about.
