Richard Barthelmess stars in a role for which Griffith had screentested Rudolph Valentino. In today's time, this film is considered by many to be one of Griffith's worst films though it might have worked better as a short film. This film was unlike others created by D.W. Griffith. According to an article written for The Cincinnati Enquirer, written on the 16 of November 1919: "Unlike other recent Griffith production, Scarlet Days is a story of the old West, of the gold rush days of 49- Bret Harte transferred to the screen!" The Western film genre was expanding at this time and Scarlet Days fits into this category. Western films were popular for this time.
