Old Cowboy Movies, also known as Oaters, are a genre of Western films that were popular in the United States from the 1920s to the 1950s. These films typically featured cowboys and outlaws, often with a moral lesson at the end. Oaters often featured singing cowboys, such as Gene Autry and Roy Rogers, and were often set in the American West. They were usually low-budget productions and were often filmed in the deserts of California and Arizona.
