- Acting for Two: Jonathan Hyde 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.
- 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 Zathura came out, which used cards.
- Deleted Scene: 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.
- Enforced Method Acting: Robin Williams 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.
- Fake American: Australian-born Jonathan Hyde plays Sam Parrish and Van Pelt.
- Font Anachronism: The typeface used for the board game Clue came out only in the 1990s.
- Lying Creator / Trolling Creator: Robin Williams 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".
- Reality Subtext: 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 "Going Postal."
- Technology Marches On: 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.
- What Could Have Been:
- Tom Hanks was the first choice to play Alan Parrish. Dan Aykroyd, Chevy Chase, Sean Connery, Kevin Costner, Richard Dreyfuss, Michael Douglas, Rupert Everett, Harrison Ford, Andy Garcia, Richard Gere, Mel Gibson, Michael Keaton, Kevin Kline, Bill Murray, Bill Paxton, Arnold Schwarzenegger and John Travolta were also considered.
- Scarlett Johansson 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. A Fter Alan was beaten up by Billy Jessup and his gang, A Lan'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.
- Actor Allusion: Aunt Nora in the movie is a pretty normal woman, played by Bebe Neuwirth. In the cartoon, she's basically Lilith Sternin, in attitude and appearance.
- The Merch: Parker Brothers released a handheld electronic game.
