Walter Satterthwait called my attention to this info about one of the actors in the film.
Paul Kelly (actor) - Wikipedia, the free encyclopedia: "Born in Brooklyn, New York, Kelly began his career as a child actor in silent films at age 7 before growing up to become a Broadway and film actor. Kelly appeared in over one hundred movies, most of them as a tough guy character actor in the 30s, 40s and 50s.
His career momentum was briefly halted with a two-year (1927-1929) forced hiatus when he spent 25 months in California's San Quentin prison for beating to death actor Ray Raymond in a fistfight. Raymond's widow, Dorothy MacKaye, later married Kelly. She was briefly imprisoned for being an accomplice in the murder."
