Bob Clark did make an "official" sequel in the 90's.

It was retitled "My Summer Story" on home video. Obviously all the parts were recast because of the passage of time, but it did have Jean Shepard's narration.

Your images aren't showing up, SilverWook.

Several movies, TV and theatrical, were made based on Jean Shepard's stories and star the Parker family. There's:

A Christmas Story
My Summer Story
Ollie Hopnoodle's Haven of Bliss
The Great American Fourth of July and Other Disasters
The Phantom of the Open Hearth

I've read his book In God We Trust, All Others Pay Cash, from which most of these movies took their stories. It's really good, and A Christmas Story perfectly captures Shepard's tone.

I'm curious if A Christmas Story 2 is based on a Jean Shepard story, or is an original script.
