* AFIS100Years100Thrills: #84
* AFIS100Years100MovieQuotes:
** #69, "They're here!"
* 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...
* HeyItsThatVoice: In the third film, Kane is voiced by Creator/CoreyBurton.
* InMemoriam: The third film was dedicated in memory of Heather O'Rourke, who tragically and unexpectedly died a few months before the film was released.
* 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.
* Main/TechnologyMarchesOn: If the 80's fashion doesn't date the film to the modern-day viewer, surely Carol Anne playing with a Speak & Spell in the third movie will.
