Also haven't seen this movie since my childhood (played on Channel 5 in NYC, which seemed to run a lot of 20th Century Fox movies; remember that's the channel that first showed LAURA) and agree that it's a charmer (from my memories) and one of the two starring vehicles for Peggy Ann Garner (in DAISY KENYON, for example, Garner is only in a supporting role as the elder of Dana Andrews's two daughters; Connie Marshall is the other, as she is also the sister in HOME SWEET HOMICIDE).
After A TREE GROWS IN BROOKLYN, 20th Century Fox knew they had a "star" (Garner won one of those juvenile Academy Awards for it), but they had no idea what to do with her.
But Garner was put into JUNIOR MISS and HOME SWEET HOMICIDE, her two starring vehicles. JUNIOR MISS has also not been shown in eons, but i remember it with great fondness. (Was the name of her best friend - played by Barbara Whiting - "Fuffy"? It's hard to forget that.)
I certainly hope that those two films will reappear again, but we all know how difficult Fox is!
(But DAISY KENYON is coming to DVD, one of the rare Crawford vehicles for 20th Century Fox, and Peggy Ann Garner and Connie Marshall are also in the cast.)
