JM's last film. She sings 5 songs (per Soundtracks).
5th of 7 Lassie films.
3rd of 11 films for Claude Jarman Jr (b. '34); first film was The Yearling ('46).

Exactly what you'd expect from the great JM, Lassie, and the teen from The Yearling, especially since that teen is an orphan, and JM is shown to lose her husband to the war and her son to a car accident: something musical and sentimental. But it's well done.

Percy Kilbride plays country sage, proprietor of the local store. Lloyd Nolan is an odd character, seemingly thrown in toward the end of the film, if only to argue with JM in the near-final scene. Margaret Hamilton is there purely for local color, to show JM adjusting to her new environment.
