The Jennings brothers were members of the outlaw band known as "The Long Riders." They were captured and imprisoned, but later given a pardon by President Theodore Roosevelt. Al J. Jennings then became a lawyer and evangelist and, in collaboration with writer Will Irwin, contributed a series of autobiographical stories to The Saturday Evening Post. The story from which this film was taken was "based on absolute facts" as noted by one reviewer.
The term "From soda to hock" means "from start to finish," and refers to the card game Faro.
Although some contemporary sources list the film's title as The Lady of the Dugout (1918), a print of the film reveals that the onscreen title was "The Lady of the Dug-Out."
The story takes place in Texas but the mountains of California are in the background in the outside scenes.
