* ActingForTwo: In the French dub, Creator/RogerCarel voiced both Roquefort and Lafayette.
* BillingDisplacement: The opening credits roll call list O' Malley's credit up first alongside Duchess and Roquefort, despite not appearing until the second third of the movie. Likewise, the voices for Marie, Toulouse, and Berlioz were listed as the third set following those for the Alley Cats, who don't appear until about forty minutes in.
* {{Blooper}}: The sidecar on Edgar's motorcycle constantly switches sides.
* ChildrenVoicingChildren: Toulouse and Berlioz were both voiced by child actors in the original release as well as all foreign dubs of the film.
* TheDanza: Contrary to popular belief, Scat Cat was ''not'' originally intended to be voiced by Creator/ScatmanCrothers, but by Music/LouisArmstrong. It was, in fact, a coincidence when Armstrong turned the role down and it ended up going to Crothers, who just so happened to have a similar nickname.
* DiedDuringProduction: This was the last film that Creator/WaltDisney personally greenlit, and the first film that [[Creator/{{Disney}} his studio]] made without him.
* FakeNationality: None of the main voice-actors are Parisians, despite the film taking place there, since the movie is an American production.
* FakeRussian: American actor Thurl Ravenscroft plays the Russian Billy Boss.
* FollowTheLeader: Basically Disney's version of ''WesternAnimation/GayPurree''.
* NonSingingVoice:
** Duchess's singing voice was done by Robie Lester, who also dubbed for Gabor in ''WesternAnimation/TheRescuers''.
** Frou-Frou's solo during the "Everybody Wants to Be a Cat" reprise was provided by Ruth Buzzi of ''Series/RowanAndMartinsLaughIn'' fame.
* OneBookAuthor: This film is the only voice acting roles for former child actors Liz "Louise" English and Dean Clark. After the film's release, Liz English (Marie) became a regular on The Benny Hill Show between 1978-1986 and one of the original members of Hill's Angels. Nowadays she's more active in plays, theaterical shows, and nationally-touring musical-theatre productions in the UK. Her most recent appearance on television was in a UK commercial for "Key Advice Release" from 2018 as one of the characters. Occasionally she would sign autographs featuring Marie such as animations cells from the film and various Marie merchandise. However, The Aristocats is the only acting role for Dean Clark (Berlioz), who hasn't reappeared in anything since then.
* TheOtherDarrin: In the [[https://www.youtube.com/watch?v=yH8cWdIaG-w Disneyland Records adaptation]] of the film, Duchess alongside Marie, Toulouse, and Berlioz are voiced by uncredited actors. However, the original actors from the film reprise their roles as Roquefort, alongside Napoleon and Lafayette.
* PropRecycling: Many of the vehicles in the film are actually recycled from ''WesternAnimation/OneHundredAndOneDalmatians'', especially the Baduns' truck and the moving van. The vehicles in that film were white models with outlines drawn on the edges, [[{{Rotoscoping}} filmed with a stop-motion camera]] and then photocopied onto cels. Because of time and money constraints, rather than give build new models for the milk truck and the baggage van, Disney simply reused them for these roles in this film, respectively.
* ReferencedBy:
** ''Film/OneHundredAndOneDalmatians1996'': When the puppies are about to receive their collars, they are shown watching TV, much like in [[WesternAnimation/OneHundredAndOneDalmatians the original film]]. Here, they are shown watching ''The Aristocats'', during the closing of the "Everybody Wants to Be a Cat" sequence before changing the channel to ''Film/HomewardBoundTheIncredibleJourney'', showing Shadow being reunited with Peter.
** ''WesternAnimation/FostersHomeForImaginaryFriends'': In "[[Recap/FostersHomeForImaginaryFriendsS2E5MacDaddy Mac Daddy]]", Bloo tries to send Cheese away to Timbuktu, much like Edgar tried to do to Duchess and her kittens. Cheese gets sent back to Foster's due to insufficient postage to tolerate smell.
** ''WesternAnimation/HouseOfMouse'':
*** O'Malley and the Alley Cats have appeared on the show from time to time. A RunningGag is that they are constantly invited to perform at the House, but something always happens that results in their act being canceled.
*** In the ''[=MouseWorks=]'' short "Pluto's Magic Paws", Pluto is looking for something dog-related to watch on television, only to find that [[YourTelevisionHatesYou every channel is showing cat-centric programming instead]]. One of the movies playing is ''The Aristocats''.
** ''WesternAnimation/RobinHood1973'' [[RecycledAnimation re-uses some animation from the film]], such as the band playing music and Maid Marian dancing with Robin in "The Phony King of England".
* StillbornFranchise: Creator/DisneytoonStudios planned to make [[http://animatedviews.com/2008/disneytoon-studios-and-the-sequels-that-never-were-with-tod-carter/ a direct-to-video sequel]]. While the first film had the kittens' nemesis as a misguided butler intent on stealing their fortune, ''The Aristocats II'' created a similar dynamic by pitting them against a jewel thief on the open seas aboard a luxury cruise ship. There was also a young kitty love interest for Marie who became the focal character of the film. The ship would travel from places like France, Scotland, England, Spain, etc, thus creating a creating a new atmosphere of different places in the early 1900s. It was scheduled to be released in 2007, but it was abandoned in early 2006 after Disney acquired Creator/{{Pixar}} and Creator/JohnLasseter pulled the plug on all the direct-to-DVD sequels that had not yet entered production. Creator/TaraStrong was also going to voice Marie for the sequel. In animatics for the sequel, Duchess was also going to be voiced by Russi Taylor.
* SwanSong:
** This was the final acting credit for Disney stalwart Creator/BillThompson. His arsenal of roles include [[WesternAnimation/AliceInWonderland1951 the White Rabbit]], [[WesternAnimation/PeterPan Mr. Smee]], [[WesternAnimation/LadyAndTheTramp Jock]], and Ranger Woodlore. He gives a rather memorable performance as Uncle Waldo.
** It was also actor/singer Maurice Chevalier's final film appearance before he died on January 1, 1972.
* WhatCouldHaveBeen:
** ''The Aristocats'' was originally developed as a two-part live-action episode of ''[[Series/WaltDisneyPresents Walt Disney's Wonderful World of Color]]''. It was later decided that the story would work better as an animated feature. You may have noticed that the opening credits say the film is, "based on a story by Tom [=McGowan=] and Tom Rowe." [=McGowan=] and Rowe were, in fact, the screenwriters of this never-filmed ''Wonderful World of Color'' version.
** A song called “[[https://youtube.com/watch?v=exIOVsVEQbY She Never Felt Alone]]” was recorded, but never animated, about how Madame was never alone with Duchess and the kittens. It was sung at the beginning by Madame (via a recording on a new phonograph she demonstrates to the cats) and with a reprise sung by Duchess while on the “magic carpet”.
** Scat Cat was originally written with Music/LouisArmstrong in mind, with his original name being Satchmo Cat. Unfortunately, illness kept Pops from being able to play the intended character who was then reworked and recast with Scatman Crothers. Since his facial features were already patterned after Pops, they told Crothers to "pretend you're Satchmo". "Everybody Wants to Be a Cat" replaced the song the Sherman Brothers wrote for Armstrong, "Le Jazz Hot". Armstrong died seven months after the movie's release.
** There was a deleted character named Elvira who was Madame Bonfamille's maid. She would have formed a BigBadDuumvirate with Edgar after singing a VillainLoveSong with him called "[[CutSong Court Me Slowly]]."
** Early on in production O'Malley was going to have stripes but Wolfgang Reitherman having learned from working with Shere Khan on their previous film decided stripes to be too expensive to animate and was so O'Malley was left a straight-up orange tabby.
** [[https://static.tvtropes.org/pmwiki/pub/images/l98u73e.jpg The original character designs for Marie, Toulouse and Berlioz]] looked very different compared to their final designs. Toulouse originally looked more like a tiger cub, Marie also used to look chubby complete with dimples, and Berlioz's original design was sweeter. The kittens also used to look fluffy, with a lot of fur.
** [[http://andreasdeja.blogspot.com/2015/05/roquefort.html The original character design for Roquefort]] had him looking very similar to the mice from ''WesternAnimation/{{Cinderella}}'' and ''Literature/BenAndMe''.
** According to the book ''Mouse Under Glass'', Creator/BorisKarloff was the first choice to play Edgar the Butler.
** At one point during the film's production, Toulouse was named "Dopey" [[https://static.tvtropes.org/pmwiki/pub/images/1sz3vft.jpg which is seen in this concept art for the kittens.]]
** Susan Olsen of [[Series/TheBradyBunch Brady Bunch fame]], was considered to voice Marie.
** Part of the movie would have taken place [[http://jimhillmedia.com/editor_in_chief1/b/jim_hill/archive/2012/08/21/would-walt-s-version-of-quot-the-aristocats-quot-have-been-a-bigger-hit-for-disney-studios.aspx in the sewers of Paris]] but Wolfgang Reitherman thought the water and lightning effects would cost too much to animate.
** There were plans for an ''[[http://jimhillmedia.com/editor_in_chief1/b/jim_hill/archive/2008/02/05/toon-tuesday-disney-s-the-aristocats-the-animated-series.aspx Aristocats: The Animated Series]]'' way back in 2003. [[http://i.imgur.com/JpA90aS.jpg Marie and her brothers, Berlioz and Toulouse, would be turned into teenagers]]. And it would've given Marie (who was supposed to be the main character of this new "Aristocats" show) someone new to bounce off of. They invented this teenaged cat similar to O'Malley the alley cat, called Delancey, who could dance like a combination of Music/JustinTimberlake and Music/{{Usher}}. And then to round out the cast "the Street Cats" were created. The basic idea here was to reinvent ''The Aristocats'' so that this franchise would then appeal to your typical Disney Channel/Toon Disney watcher. But when Disney bought Creator/{{Pixar}} in 2006, it was cancelled along with the planned sequel, the ''Aristocats II'' film. Only [[https://vignette.wikia.nocookie.net/disney/images/f/f9/AristocatsDesigns.png/revision/latest?cb=20130519231703 concept art of]] [[https://vignette.wikia.nocookie.net/disney/images/b/bf/Aristo11.gif/revision/latest?cb=20191115192204 Marie,]] [[https://vignette.wikia.nocookie.net/disney/images/b/b7/Toulouse_and_Berlioz.jpg/revision/latest?cb=20150706142328 Toulouse, and Berlioz]] survive.
