Shine On, Harvest Moon is a 1938 American Western film directed by Joseph Kane and starring Roy Rogers and Mary Hart. Written by Jack Natteford, the film is about a crazed outlaw who looks up a former partner, who has "gone straight", and tries to blackmail him with his past into resuming a life of crime. When this plan fails, the outlaw and his two psychopathic sons re-establish their gang and begin a wave of violence and rustling in the surrounding area, and arrange evidence that his former partner is the actual criminal. The partner's daughter engages the sympathy of Roy Rogers in bringing the truth to light and the real villains to justice. The supporting cast includes Stanley Andrews and William Farnum, and features Lulu Belle and Scotty in their only film appearance.
