- Career Resurrection: Before this movie, Pierce Brosnan's career was pretty stagnant, with his only real high profile role being the lead in Remington Steele. He was considered for his most famous role as early as the mid 1980s but his Remington Steele contract put a stop to that. Thankfully, this was the shot in the arm before finally landing the role of 007 in 1995.
- The Cast Showoff: Robin Williams has always been famous for his impersonations - and this is a movie revolving around it where he impersonates a Scottish, female Mr Rogers.
- The Danza: Todd the Bartender, played by Todd Williams.
- Deleted Role: Polly Holliday's part as the antagonistic next door neighbor, Gloria Chaney, was originally a prominent supporting character and had a much larger role in the film. Due to time constraints, most of her scenes were cut. As a result, Gloria is only seen at the film's beginning and briefly in the background during the Mercedes Benz scene. All of her deleted scenes were included as special features on DVD.
- Fake American: Lydia Hillard, the eldest daughter, is played by Canadian-born Lisa Jakub.
- Fake Brit: Technically Pierce Brosnan, who is Irish but moved to London when he was ten. Daniel is an in-universe example in his Mrs Doubtfire disguise.
- Pop Culture Urban Legends: One biography claims that Robin Williams tested out how believable the disguise was by going into a bookstore wearing it - and wasn't recognised at all.
- Real-Life Relative: Robin Williams' brother plays the bartender in the pool scene.
- Reality Subtext: Sally Field was going through a divorce during filming.
- Stillborn Franchise: Talk of a sequel began in 2003, with a script being written by Bonnie Hunt. Robin Williams was set to return in disguise as an old nanny like in the first movie. Due to problems with the script, re-writing began in early 2006 as Robin was allegedly unhappy with the plot. The film was expected to be released in late 2007, but following further script problems, the sequel was declared "scrapped" in mid 2006. The sequel's story was originally said to involve Williams, as Mrs. Doubtfire, moving close to his daughter's college, so he could keep an eye on her. Serious discussions regarding the sequel re-ignited in April 2014, with an announcement that Robin Williams and Chris Columbus would be teaming up with Fox 2000 to produce the sequel. Williams' sudden death just four months later ultimately sealed the project's fate once and for all. No one replaced him either.
- Stunt Double: No, that's not Robin Williams setting his blouse on fire. That's a stunt double, and a pretty obvious one at that. However, first time viewers are likely to miss it because the fire and frenetic action distracts from the stunt double's face.
- Technology Marches On: Daniel's scheme of calling several times as various nannies would not work today as Miranda would most likely figure out that the caller ID is the same for each nanny. He would have to use more elaborate means such as using various phones (workplace phones, prepaid or borrowed cellphones, what few payphones still remain, etc.), spoofing his caller ID or sending emails from various throwaway addresses (albeit at the cost of the whole Man of a Thousand Voices shtick).
- Throw It In!: Mara Wilson ad-libbed the princess line.
- What Could Have Been:
- The movie's ending changed several times. The first script had Daniel and Miranda becoming Amicable Exes as they do in the finished film. The original scriptwriter was fired, and a different ending was rewritten where they remarry. This was changed after executives realised that they didn't want to give the Unfortunate Implications that all divorced parents eventually get back together.
- The original author suggested Warren Beatty for the role of Daniel because she thought it would be funny to see him (a known womanizer) having to disguise himself as an old lady in a film. Other candidates included Jason Alexander, Rowan Atkinson, Kevin Bacon, Alec Baldwin, Jeff Bridges, Matthew Broderick, John Candy, Jim Carrey, Chevy Chase, Bryan Cranston, Billy Crystal, Jeff Daniels, Robert De Niro, Chris Farley, Harrison Ford, Michael J. Fox, Richard Gere, Mel Gibson, John Goodman, Tom Hanks, David Hasselhoff, Dustin Hoffman, Michael Keaton, Kevin Kline, Wayne Knight, Nathan Lane, Steve Martin, Dudley Moore, Bill Murray, Mike Myers, Bill Paxton, Dennis Quaid, Kurt Russell, Adam Sandler, Arnold Schwarzenegger, Martin Short and John Travolta.
- The role of Stu was written with Tim Allen in mind, but he turned it down due to scheduling conflicts with Home Improvement.
- Stuart was supposed to be more of a typical Jerkass—wanting to send the kids Off to Boarding School, etc.
- Blake Lively was considered for Natalie Hillard, and made it to the final round of auditions between her and Mara Wilson.
- Chris Columbus tried to get a sequel off the ground for a long time (despite the source novel not having any), but Robin Williams was unsatisfied with every script. In a tragic twist, it finally did get some forward momentum in 2014, but Williams' suicide naturally ended any chance of it.
