* CreatorPreferredAdaptation: Creator/StephenKing preferred [[spoiler: the significantly bleaker ending of the film.]]
* FollowTheLeader: ''VideoGame/HalfLife1'' was inspired by the book.
* RealLife/MeanCharacterNiceActor: Marcia Gay Harden is everything Mrs. Carmody is not.
* WhatCouldHaveBeen:
** The original draft included some more details about the setting that was left out. Most noticeable was that there was supposed to be a scene that shows the Arrowhead Project going wrong.
** Mrs. Carmody was originally to be depicted as eccentric to begin with. There's also a scene cut out that was suppose to show that her cult caused more casualties.
