After the Civil War, Cord McNally (John Wayne) searches for the traitor whose perfidy caused the defeat of McNally's unit, a shipment of gold to be stolen, and the loss of a close friend.

I loved the beginning with the train robbery. Every part of it was executed perfectly, and the first ten minutes or so are probably the highlight of the film. And then the idea that the yanks and rebels could be friends was questionable but nice... and the shift from the war and the heist to tracking down a traitor, great. But it seemed to have a good deal of turns and subplots that were not quite necessary.

The worst was Jennifer O'Neill, who played Shasta. I would gladly give this film another star if it was not for her. Every line was delivered so poorly. I guess Howard Hawks feared John Wayne was too old for the role... I thought Wayne was great. It was O'Neill that was the weak link. She just has no acting ability to speak of.

Also, a special nod to Jack Elam, who was the comic relief. His wit and delivery (almost) make up for O'Neill, and on that count I have revised my 6 stars in 2015 to 7 stars in 2016 upon a second viewing. This may not be the best known Hawks-Wayne collaboration, but it certainly has its strong points.

This has to be unique in the history of Hollywood. Leading director and screen legend Howard Hawks loved this film so much that they made three variations of the same movie. By the time Rio Lobo was made, the theme was getting a bit thin, but it's still grand entertainment.

The first part of the film is set during the Civil War with John Wayne pursuing Confederates who are stealing army payrolls. He does catch up with them and the Civil War ends. He befriends his erstwhile enemies and asks for their help in locating the informer who was giving them information.

That all sets the scene for the third variant of Rio Bravo/El Dorado theme. Playing the old codger part is Jack Elam who by now had quit being a screen menace and was doing comedy and doing it well. The two younger sidekicks are the former Confederate enemies, Jorge Rivero and Chris Mitchum.

Rio Lobo had the presence of two stars of the Mexican cinema, Jorge Rivero and Susana Dosamantes. Dosamantes played Mitchum's girlfriend and Jennifer O'Neill played the Angie Dickinson part although Wayne was now deciding he was too old for the romance. She pairs off with Rivero.

In a small bit part is Sherry Lansing who left acting soon after Rio Lobo and really hit the big time, going into the production end of the movie business and becoming head of first 20th Century Fox and later CEO of Paramount.

The two principal villains are Victor French who played the neighbor on Little House On The Prarie and Mike Henry who was one of several screen Tarzans.

It's a good John Wayne western and that takes in a whole lot of territory pilgrim.

The third and final film in Howard Hawks's famous trilogy of westerns starring John Wayne; the first was RIO BRAVO and the second EL DORADO. This late-stage entry in the genre is far better than I was expecting, a bright and colourful western with an interesting cast and an ageing star who still has the power to kick backside with the best of them.

The opening of RIO LOBO is particularly astute, featuring a heist on a train carrying a gold shipment which is very well directed and exciting. Wayne plays the usual stock hero and wrings maximum presence out of his part, only this time around he's supported by a mixture of old hands (Jack Elam) and new faces (Mexican star Jorge Rivero and Christopher Mitchum).

The narrative slows down after the first section which is understandable given the passage of time. However, it soon picks up in scenes which are very reminiscent of RIO BRAVO, and keeps bubbling along pretty well until the action climax. I did find the villains to be rather weak in this film but the heroes are so larger than life that it doesn't really matter. Jennifer O'Neill's female lead is an irritant rather than an asset but she's not bad enough to spoil what is an overall fun picture.
