Change came when one day she showed up at the lot of Action Pictures, which produced B westerns, and impressed its owner Lester F. Scott Jr., with her presence. He decided to take a chance on a complete unknown, and she was cast in over twenty westerns in a two-year period. Only receiving $25 a picture, Arthur suffered from difficult working conditions: "The films were generally shot on location, often in the desert near Los Angeles, under a scorching sun that caused throats to parch and make-up to run. Running water was nowhere to be found, and even outhouses were a luxury not always present. The extras on these films were often real cowboys, tough men who were used to roughing it and who had little use for those who were not." The films were moderately successful in second-rate Midwestern theaters, though Arthur received no official attention. Aside from appearing in films for Action Pictures between 1924 and 1926, she worked in some independent westerns, including "The Drug Store Cowboy" (1925), and westerns for Poverty Row, as well as having an uncredited bit part in Buster Keaton's "Seven Chances" (1925).
