* ActorSharedBackground: Big Russ Thompson says he was captain of the football team in high school. Creator/MattFrewer was the quarterback of his high school team in real life.
* AdoredByTheNetwork: You would have been hard pressed to find a time in the early 2000s when the show ''wasn't'' being re-ran on Creator/DisneyChannel.
* BillingDisplacement: In the first film, all four of the actors who play the parents are billed above all four of the actors who play the kids, despite the kids getting much more screentime.
* CaliforniaDoubling:
** The first movie was set in Fresno, but was shot in Mexico.
** The TV series was set in Colorado, but filmed in Calgary, Alberta, Canada.
* CreatorsOddball: Creator/StuartGordon and Creator/BrianYuzna, both best known for making low-budget horror B-movies, writing a Disney family comedy.
* TheDanza: Amy O'Neill as Amy Szalinski.
* DawsonCasting: Averted. The kids were played by Amy O'Neill (17), Thomas Wilson Brown (15), Jared Rushton (14), and Robert Oliveri (10). Played straight on the TV series, where Hillary Tuck started playing Amy at 19, although Creator/ThomasDekker was 10 when he started playing Nick.
* FakeAmerican: The Canadian Creator/RickMoranis as American Wayne Szalinski.
* HeAlsoDid:
** The story was developed by Creator/StuartGordon, Creator/BrianYuzna, and Ed Naha. Gordon and Yuzna are known for the ''Film/ReAnimator'' series of horror movies, and Naha, who cowrote the screenplay, also worked heavily in the horror genre, writing, among other films, ''Film/Dolls1987'' and ''Film/Troll1986''.
** In addition, on the TV series, frequent director Tony Dow previously played [[Series/LeaveItToBeaver Wally Cleaver]], while Creator/JohnLandis served as executive producer.
* OnlySoManyCanadianActors: Applies to the television series, which was filmed in Canada and starred Canadian actors.
* TheOtherDarrin:
** Diane (Marcia Strassman in the first two movies, Eve Gordon in the third movie).
** The entire cast, in the TV show. For example, Wayne, portrayed by Creator/RickMoranis in the films, is played by the late Creator/PeterScolari.
** Within the TV show, Quark, who was a white terrier in the original movie, is inexplicably a larger, black-and-white dog named Matese in season one, and is replaced with another terrier in season two -- as a plot point.
** Due to Robert Oliveri's 1994 retirement, Josh Gad will be playing as Nick in the upcoming ''Shrunk''.
* PlayingAgainstType:
** In the series, Creator/GeorgeBuza played police chief [=McKenna=], instead of his usual "scary biker-thug" role.
** In the original film, Creator/MattFrewer plays a JerkJock father when his typical roles are more like Wayne.
* ReleaseDateChange: The film's original release date was December 1988, but delayed to June 1989.
* RomanceOnTheSet: While filming the TV series, lead actress Creator/BarbaraAlynWoods met and fell in love with assistant director John Lind. They married in 1999 and have three daughters, all of whom are also actresses.
* SleeperHit: ''Honey, I Shrunk the Audience'' was a surprise hit when it opened at Walt Disney World's Epcot park in 1994, running until 2010 there. It was so popular that the Imagination pavilion was re-themed to its "Imagination Institute" setting in 1999, though (thanks to Disney's penny-pinching at the time) it led to a case of TheyChangedItNowItSucks with regards to the ''Journey Into Imagination'' dark ride.
** The original film itself was one, as it unexpectedly grossed over $222 million at the box office.
* UnderageCasting:
** Creator/MattFrewer was only 30 when he played Russ Thompson in the first movie, but appeared older because of his high forehead and gaunt features. The character had two teenage sons, the elder of whom was played by Thomas Wilson Brown, aged 15 during the filming and just 15 years younger than Frewer. Frewer's onscreen wife, Creator/KristineSutherland, wasn't much older at only 33. Even Rick Moranis was only 35, and had just 18 years on Amy O'Neill, who played his daughter.
** Eve Gordon was ''35'' when she appeared as Diane in ''Honey, We Shrunk Ourselves''. She is twelve years younger than Marcia Strassman (who was 40 when she appeared in the original film), and just 11 years older than Amy O'Neill, who played her character's oldest child. (Luckily for her, both Amy and Nick are absent from ''Ourselves'' and a 35-year-old woman is perfectly plausible as the mother of a tweenage son.)
** Though less extreme than Gordon as the series is set earlier than ''Ourselves'', Barbara Alyn Woods, who played Diane in the series, was also 35 during filming of the first season. She is only sixteen years older than Hillary Tuck, who played Amy.
* WhatCouldHaveBeen:
** Creator/StuartGordon was originally intended to direct the first film, but had to bow out due to illness.
** The role of Wayne Szalinski was originally written with Creator/ChevyChase in mind due to his popularity in ''Film/NationalLampoonsVacation'', but he was busy with ''Film/NationalLampoonsChristmasVacation''. Creator/JohnCandy was also offered the role, but he declined and recommended Creator/RickMoranis. Creator/MartinShort was also considered.
** In an early version of the script, there were five kids, one of which died during the sprinkler sequence.
** ''Honey, We Shrunk Ourselves'' was originally slated for a $40 million budget, which got cut down to $7 million when Disney decided to try it as its first live-action direct-to-video release.
** Creator/RaulJulia was originally cast as Nigel Channing in ''Honey, I Shrunk the Audience'', but his declining health lead him to pull out at the last minute, with Creator/EricIdle stepping in after a chance meeting with Marcia Strassman at her hotel.
* WorkingTitle: ''The Teeny-Weenies'' (The film's script was written under this name), ''Grounded'' and ([[ExecutiveMeddling favored by Disney]]) ''The Big Backyard''.
