!!The Movie
* ActingForTwo: Creator/JonathanHyde plays both Alan's father and Van Pelt. A common theory is that Jumanji conjures up Van Pelt by taking the form of the person you had dreaded the most, and for Alan, it's his father--especially since Van Pelt spouts out the same criticism as his father.
* BillingDisplacement: Sort of. Robin Williams is billed first, yet doesn't appear until nearly a half hour into the film.
* {{Defictionalization}}: A ''Jumanji'' board game was released when the movie came out. It shared many elements with the game in the movie, aside from the supernatural elements, like the automatically moving pieces or sucking in players...we think. It also used cards, not even attempting to copy the magic-8 ball style interface. It came full-circle again when ''Film/{{Zathura}}'' came out, which used cards.
* DeletedScene:
** The novelization contains an explanation for why Nora had to talk with the principal after Peter and Judy's first day: the realtor's son called Judy out on her lies, and Peter started a fight with him.
** The 2017 Blu-ray release revealed that Carl eventually became the president of Parrish Shoes. Also, the Christmas gifts Alan gave to Peter and Judy were pairs of sneakers inspired by the game, complete with Jumanji imprinted on the bottoms.
* EnforcedMethodActing: Creator/RobinWilliams admitted that he did not need to act startled for the scene where Van Pelt is shooting at him, as the blank gunfire was extremely loud on-set.
* FakeAmerican: Australian-born Jonathan Hyde plays Sam Parrish and Van Pelt. He uses a slightly American-sounding voice as Sam, but gives Van Pelt [[EvilBrit an English accent]].
* FontAnachronism: The typeface used for the board game Clue came out only in the 1990s.
* PlayingGertrude: Robin Williams was ten years older than Bonnie Hunt, and they play characters who are the same age and went to school together. David Alan Grier meanwhile is four years ''younger'' than Robin, even though Carl was an adult when Alan was a child.
* RealitySubtext:
** The gun shop owner asking Van Pelt if he's a postal worker. Around the time of the movie, there had been a lot of news stories about postal workers going crazy and shooting up their workplaces, from which we get the expression "GoingPostal."
** Robin Williams noted the parallels of Alan and his father's relationship to his own father's with his grandfather.
* SequelGap: [[Film/JumanjiWelcomeToTheJungle A stand-alone sequel]] was released 22 years after the original.
* ShownTheirWork:
** Alan advising everyone to get to higher ground when the monsoon hits. In a jungle, dense rainfall and heavy humidity can rot human flesh very quickly, so this is pretty apt advice.
** It was indeed a crocodile that Alan wrestled for Sarah.
* TechnologyMarchesOn: Referenced when they start playing the game in 1969, with Sarah remarking that the self-moving pieces must be done with magnets. When the kids continue the game in 1995, Judy suggests it's done with microchips, which actually makes ''less'' sense. Plus, Carl proudly showing off his prototype for a modern basketball shoe.
* TrollingCreator: Creator/RobinWilliams would often give fake answers to people who asked him what the title meant. "I tell them it's an island in the Caribbean. Book your travel there early".
* TypeCasting: Creator/KirstenDunst and Bradley Pierce played siblings in ''The Siege at Ruby Ridge'' a year later too.
* WhatCouldHaveBeen:
** Creator/TomHanks was the first choice to play Alan Parrish. Creator/DanAykroyd, Creator/ChevyChase, Creator/SeanConnery, Creator/KevinCostner, Creator/RichardDreyfuss, Creator/MichaelDouglas, Creator/RupertEverett, Creator/HarrisonFord, Andy Garcia, Creator/RichardGere, Creator/MelGibson, Creator/MichaelKeaton, Creator/KevinKline, Creator/BillMurray, Creator/BillPaxton, Creator/ArnoldSchwarzenegger and Creator/JohnTravolta were also considered.
** Creator/ScarlettJohansson auditioned for Judy Shepherd.
** In earlier drafts of the films, Nora was supposed to be Judy and Peter's ''mother.''
** Alan's parents wanted to send him to boarding school for a different (and better) reason than in the final draft. After Alan was beaten up by Billy Jessup and his gang, Alan's parents finally realized that Alan was not fitting in with the other children in Brantford, correctly guessing that it was because they were jealous of Alan's wealth and status as a Parrish. Therefore, they believed he would fit in better with boys at Cliffside (or "Boden" as it was called in the original draft) because they were more "his status." The end result was still the same with Alan though.
** In the original draft of the film, after being turned into a monkey, Peter slowly regressed to HulkSpeak, and lost his memory of being human and whatnot.
** In the book, the last roll produced a [[LethalLavaLand volcanic eruption]].

!!The Cartoon
* ActorAllusion: Aunt Nora in the movie is a pretty normal woman, played by Bebe Neuwirth. In the cartoon, she's basically [[Series/{{Cheers}} Lilith]] [[Series/{{Frasier}} Sternin]], in attitude and appearance.
* TheMerch: Parker Brothers released a handheld electronic game.
* WhatCouldHaveBeen:
** Creator/TimCurry auditioned for Van Pelt before being cast as Trader Slick.
** Trader Slick was intended to have a WesternAnimation/BugsBunny like New York accent.
