Oh, and Mary Steenburgen, who played Buddy's stepmother Emily in #Elf plays Ralphie and Randy's mother Mrs. Parker in #MySummerStory.

My bad, the first sequel is called #MySummerStory, aka #ItRunsInTheFamily. Jean Shepherd returned as Narrator Ralphie and Tedde Moore returned as Ms. Shields, but unfortunately everyone else was recast. The good news is Macaulay Culkin's little brother, Kieran (made famous by his depiction of Fuller, the manipulative soda-drinker in #homealone) plays Ralphie and their littler brother Christian plays Randy.
