SPOILER WARNING (for another movie, that is).

Gage Creed was the little boy in Pet Sematary who was hit by a truck, killed, and then reanimated in the burial ground.

Why is there a character of the same name in this movie (and, played by none other than King himself) ...??

A lot of King’s work cross references his other works. “The Dark Tower” mentions stuff from “The Stand”, for example.
