* AFIS100Years100Thrills: #84
** #69, "They're here!"
* AllThereInTheManual: Spielberg gave James Kahn free rein on the novelization, leading to it having ''tons'' of backstory (including Tangina's battles with demons on the spirit plane, a spectral SouthernBelle who protected Carol-Anne on the Other Side, an even ''more'' nightmarish NightmareFodder sequence of Marty in the kitchen, and--perhaps most critically--a more thorough explanation of why the ghostly activity started ''now'' rather than when the family first moved into the house) that was never even hinted at in the film.
* BeamMeUpScotty: By way of PopculturalOsmosis; the line is "This house is 'clean'" not "'clear,'" thank you, [[AceVentura Mr. Ventura]].
* DawsonCasting: Dominique Dunne was a few years older than sixteen.
* FatalMethodActing: Averted. The scene with the clown nearly choked Oliver Robbins to death but Steven Spielberg saved his life when he realized that something wasn't right during the filming of the scene. The next take had the clown prop not be as tight as before.
** FridgeHorror: The actresses portraying Dana and Carol Anne died premature deaths. If Spielberg hadn't noticed something was wrong during the shooting of that scene...
* RealitySubtext: Dana Freeling was entirely absent from the second and third movies, and in fact not mentioned at all. Her actress, Creator/DominiqueDunne, was murdered by her ex-boyfriend in 1982.
* RecycledTheSeries: ''Series/PoltergeistTheLegacy'' had little to do with any of the movies in the franchise.
