Rio Conchos

Set in the years after the American Civil War, Rio Conchos follows two Army officers who travel into Mexico on a secret mission. A former Confederate colonel has stolen a shipment of rifles and intends to sell the weapons to Apaches. Captain Haven is charged with stopping the deal, and he takes along two prisoners: Lassiter, an ex-Confederate officer jailed after killing Apaches in revenge for the death of his family, and Rodriguez, a Mexican ex-soldier. The two men are offered their freedom in return for guiding the mission.

Gordon Douglas directed the film, the ninth of the sixteen features he made in chronological order, between Robin and the 7 Hoods and Harlow. Clair Huffaker and Joseph Landon wrote the screenplay, and David Weisbart produced it for 20th Century Fox. Richard Boone plays Lassiter, with Stuart Whitman as Captain Haven, Anthony Franciosa as Rodriguez, Wende Wagner as Sally, Warner Anderson as Colonel Wagner and Jim Brown as Sergeant Franklyn. The credited cast runs to twenty-eight names.

On IMDb the film holds a rating of 6.6 from around 2,600 votes, while on TMDB it stands at 6.3 from 61 votes. Both figures point to a modest but steady level of attention, with the larger IMDb sample indicating a somewhat broader and slightly more favorable response among viewers than the smaller TMDB group. Running 107 minutes, it is a Western produced in the United States and released in late October 1964.
