Filmed in 1946, Tenth Avenue Angel is yet another treacly vehicle for little Margaret O'Brien. The juvenile star is cast as Flavia Mills, an 8-year-old tenement dweller who insinuates herself into the lives of several down-and-outers, among them ex-convict Steve Abbott (George Murphy). Flavia's well-intentioned efforts to help Steve go straight, and to promote the blossoming romance between Steve and Susan Bratten (Angela Lansbury), are destined to hit several emotional roadblocks before the "End" title. Disillusioned by the contradictory behavior of her adult friends, Flavia eventually learns not to give up on the human race just because of a few setbacks. The Harry Ruskin/Eleanor Griffin screenplay was based on a story by Angna Enders, which in turn was based on a vaudeville sketch by veteran mystery writer Craig Rice.
