Edit: Oh, and silly me, I forgot Jean Shepard's four "Ralphie" films that appeared on PBS' American Playhouse. These are more stories about "Ralphie" from "A Christmas Story" at different times in his life. One of them, "The Great American Fouth Of July ... And Other Disasters" stars Matt Dillon as Ralphie in his High School years. The four films are:
The Phantom of the Open Hearth (1976)
The Great American Fourth of July ... (1982)
The Star-Crossed Romance of Josephine Cosnowski (1983)
and
Ollie Hopnoodle's Haven of Bliss (1988)
Look 'em up on IMDB for details.
