Query: Good movie!

Howard Hawk's swansong is a good one. The train robbery at the beginning of the movie is exceptionally done, and it gets this film off to a fast start. It sags a bit in the middle, but is bolstered by the comic performance of Jack Elam, who is downright hilarious. Great gunfight at the end. Supporting actors are OK, but could have been a whole lot better. You couldn't find two more beautiful women than Jennifer O'Neill and Sherry Lansing, and they certainly add to the dynamics of the movie.Duke, as usual, delivers a fine performance. The similarities in plot line to El Dorado and Rio Bravo are obvious, but Hawks again does a very nice job. Jack Elam's character really saves this movie, though, because the middle is downright slow. Overall, not John Wayne's best, but good.
