On May 8th 1958, just one week into shooting Ricky Nelson celebrated his 18th birthday. As a gift, John Wayne and Dean Martin gave him a 300 lb. sack of steer manure, which they then threw Nelson into as a rite of passage.
John Wayne had deliberately moved away from westerns after The Searchers (1956), but none of his films since then had been particularly successful or well received. This film was a return to the genre for him.
Howard Hawks did not want to cast Ricky Nelson, whom he considered to be both too young and too lightweight, and deliberately gave him the fewest possible number of lines for a third-billed star. However, he later admitted that having Nelson's name on the poster had probably added $2 million to the film's box office performance.
For most of the film Chance (John Wayne) has the front of his hat turned up to make him look a little soft and friendly. However in the tough guy scenes when Chance informs Nathan Burdette that he will have Stumpy kill his brother if there is any trouble, the front of the hat is turned down, in traditional tough guy mode.
Howard Hawks always wanted someone who would connect with teenagers to play Colorado. Reportedly, his first choice was Elvis Presley, who was enthusiastic about the opportunity. Unfortunately, Presley's manager, Colonel Tom Parker, wanted too much money and top billing. Neither Hawks nor John Wayne would have any of it, so the search continued. Presley joined the US army in March 1958, two months before filming began.
There are only five close-ups in the movie: Joe firing his gun, Dude's hands trying to roll a cigarette, Dude pouring a shot of whiskey back into the bottle and a beer glass where a drop of blood falls in, alerting Dude to a gunman in the bar waiting above him in ambush. Chance's boots tapping together in Sheriff's office as he's sitting in a chair.
After seeing the film, Gary Cooper said it was "so phony, nobody believes in it." Ironically, Cooper had been a visitor to the set since he was filming The Hanging Tree (1959) nearby. "Rio Bravo" is considered to be John Wayne and Howard Hawks' reply to Gary Cooper's own film High Noon (1952) because neither Wayne or Hawks thought a real lawman would want or need to ask for help in handling a problem like Cooper's character did in that film.
Inside joke: When Chance (John Wayne) wants to deputize Colorado he asks Stumpy (who is off camera) where he keeps the deputies' badges. While Chance is looking for the badges, Stumpy (Walter Brennan) still off camera tells him to look after his own props. Wayne started off in movie as a prop man and was known to get irate if the props were not where they were supposed to be.
Dean Martin's agent approached Howard Hawks to consider his client for the role of the drunken deputy Dude. Hawks agreed to meet with Martin at 9:30 the next morning. When Hawks learned that Martin had done a show in Las Vegas until midnight, and hired a plane to fly him to the meeting, Hawks was so impressed that he simply sent Martin to get a costume and told him he had the part.
John Wayne's working script for the film was auctioned by Heritage Auctions for $20,315 by the Texas-based company. All but last three of its 122 pages were folded in half, a habit that the actor had of doing with all of his working scripts.
The movie had an interesting preview trailer. In the trailer, Ricky Nelson finishes playing his guitar, then he turns to the camera and talks about the exciting nature of the film. After some clips are shown, they cut back to Nelson who lists the cast members. When he does not mention his own name, we hear the voice of Dean Martin say off camera "What about Rick Nelson"?
Although Harry Carey Jr. was listed in the credits on-screen, he does not appear in the picture. Carey had a drinking problem at the time. He called director Howard Hawks "Howard" instead of "Mr. Hawks" on one of his first days on the set, infuriating Hawks. His contract, including his pay and his screen credit, was honored, but his part (a townsman) was cut.
In an interview Walter Brennan stated that for years after this film was released people who met him for the first time expected him to limp like Stumpy. He said he considered it a tribute to his acting since he had to constantly remember which leg to limp on.
Feathers's dialogue was occasionally inspired by the character of "Slim" To Have and Have Not (1944), as when, after the first kiss, she says: "...it's better when two people do it," recalling the phrase "it's even better when you help;" and again later when she says, "I'm hard to get - you're going to have to say you want me," recalling Slim's "I'm hard to get, Steve - all you have to do is ask me."
The score includes the hauntingly ominous "El Degüello" theme, which is heard several times. Colorado identifies the tune as "The Cutthroat Song". He relates that the song was played on the orders of General Antonio López de Santa Anna to the Texans holed up in the Alamo, to signify that no quarter would be given to them. The tune was used the following year, over the opening credits of John Wayne's film, The Alamo (1960). Composer Ennio Morricone recalled that Sergio Leone asked him to write "Dimitri Tiomkin music" for A Fistful of Dollars (1964). The trumpet theme is similar to Tiomkin's "Degüello" (the Italian title of Rio Bravo was Un dollaro d'onore, "A Dollar of Honor").
Once when Dean Martin appeared on Perry Como's Kraft Music Hall (1948), he mentioned that he was making a western starring John Wayne and that it was directed by Howard Hawks. He then said that he was playing the part of the drunken dirty deputy. He then said, as a joke, "Why they picked me, I don't know pal."
John Wayne regarded this film as marking his transition into middle age. At 51 Wayne was starting to get overweight and he believed he was too old to play the romantic lead any more. His last four movies since The Searchers (1956) had been unsuccessful, and he felt the only way to keep audiences coming was to revert to playing "John Wayne" in every film.
Because the film starred a crooner, Dean Martin, and a teen idol, Ricky Nelson, Howard Hawks included three songs in the soundtrack. Before the big showdown, in the jail house, Martin sings "My Rifle, My Pony, and Me" (which contained new lyrics to a Dimitri Tiomkin tune that appeared in Red River (1948)) accompanied by Nelson, after which Nelson sings a brief version of "Get Along Home, Cindy", accompanied by Martin and Walter Brennan. Over the closing credits, Martin, backed by the Nelson Riddle Orchestra, sings a specially composed song, "Rio Bravo" (written by Tiomkin with lyrics by Paul Francis Webster. Nelson later paid homage to both the film and his character, Colorado, by including the song "Restless Kid" on his 1959 LP, Ricky Sings Again.
L'homme à l'étoile d'argent (The Man with the Silver Star), a 1969 album from the French comics series Lt. Blueberry was directly inspired by the film. The plot is virtually the same. Blueberry plays the role of sheriff John T. Chance; McClure, a whiskey-adoring old man, combines the roles of Dude and Stumpy; Dusty plays the role of Colorado; Miss March, the teacher, plays the role of a less morally challenged Feathers; and instead of the Burdettes, here we have the Bass brothers.
One day after the April 4, 1959 release date, ABC aired Lawman: The Souvenir (1959), which starred John Russell playing Marshal Dan Troop. Instead of trying to break someone out of jail, Russell's character Marshal Dan Troop was trying to recapture a jail escapee. Both productions were filmed at the Warner Brothers Burbank studio.
