!!Trivia Tropes
* ActingForTwo: Creator/BenBurtt provides the voices for both WALL-E and M-O.[[note]]Not counting "Foreign Contaminant"[[/note]]
* AwesomeDearBoy: Creator/SigourneyWeaver took the role of the ship’s computer so she could see what it was like to be [[Film/{{Alien}} the Mother]].
* TheDanza: Creator/JohnRatzenberger (a.k.a. Pixar's Mascot, a.k.a. Pixar's Good Luck Charm) plays John.
* {{Defictionalization}}:
** It may not be directly something out of the film, but Anki's [[https://www.anki.com/en-us/cozmo Cozmo]] is practically a working version of a robot in the film's universe.
** And yes, [[MegaCorp Buy n Large Corporation]] exists [[https://www.nationstates.net/nation=bnl_corporation as a nation]][[{{Beat}} ...]] in Website/NationStates.
* EarlyDraftTieIn: At one point in the tie-in game, WALL•E has to [[spoiler:rescue EVE from the garbage airlock and repair her.]] This is because the game was developed before the movie was rewritten to [[spoiler:have EVE be the one to rescue and repair WALL•E]].
* ExtremelyLengthyCreation: Andrew Stanton came up with the idea for the film while ''WesternAnimation/ToyStory1'' was still in production, during the same lunch meeting where he, John Lasseter, Pete Docter, and Joe Ranft came up with ''WesternAnimation/ABugsLife'', ''WesternAnimation/MonstersInc1'', and ''WesternAnimation/FindingNemo''. It was not released until fourteen years after that lunch.
* FocusGroupEnding: The scenes of the Earth recovering that appear during the credits were added after test audiences said that they didn't think the people on the spaceship would survive.
* HeyItsThatSound
** WALL•E's recharging sound effect is the Mac boot-up sound.
** A behind-the-scenes short reveals that the sound of WALL-E's treads is made with a WWII crank-operated radio generator.
** Some of Ben Burtt's sound designs are derived from those used in the ''Franchise/StarWars'' films, as well as Creator/SkywalkerSound's library.
* PermanentPlaceholder
** Elissa Knight recorded the lines for Eve just to give the directors something to work with until a more famous voice actress was contracted, but they liked her performance so much that they kept it in.
** The use of ''Music/AlsoSprachZarathustra'' in a climactic scene was originally put in as a joke, until the filmmakers saw a test audience member pumping his fist in triumph. They left it in.
* RealLifeRelative: Benjamin A. Burtt, who was a sound effects apprentice on the film, is the son of sound designer Ben Burtt.
* RevivalByCommercialization: The use of ''Theatre/HelloDolly'' songs generated massive publicity and sparked some talk of a revival, which would happen in 2017.
* TechnologyMarchesOn: If you look closely at the HAN-S robots, their display shows one of the sample images from Windows XP.
* ViralMarketing: Pixar set up [[http://buynlarge.com/bnl.swf a realistic Buy n Large website]] before the movie came out. Sadly, the link now sends you to the official Disney website for ''WALL•E''.
* WhatCouldHaveBeen
** One of the film's earlier cuts (which is shown in the film's commentary and bonus material) has a lot of trivia of its own. Act 1 (which has WALL•E meet EVE) was mostly the same, but Acts 2 & 3 were vastly different from the finished movie.
*** Originally, [[HumanitysWake humans were extinct]], and EVE was instead brought to Earth by [[BlobMonster gelatinous blob aliens]] called the Gels that were revealed at the end to be [[HumanAllAlong highly-evolved humans]]. They would have spoken in a [[SpeakingSimlish made up language that the audience would not be able to understand]] (averting EternalEnglish). Basically, the sounds-as-dialogue-replacement would have been present through the ''whole movie''.
*** The Gels had a very different society when contrasted with the humans in the final movie. They weren't all stuck sitting on hover chairs, had a king and queen, and the Axiom was actually a small fleet of ships that could attach to each-other. Also, they all treated the Axiom's robots very poorly, antagonizing them at every opportunity and even senselessly destroying them on some occasions.
*** Captain [=McCrea=] was a lot more slovenly in an earlier draft, and spoke in very slurred speech that sounded like degraded English, a holdover from when the humans were still blobs. He also depended on AUTO to do just about everything and freaked out at the slightest hint that something wasn't exactly as he was accustomed to. This was cut because viewers couldn't take the character seriously and thought he was simply dumb.
*** Ultimately, as appealing as the blob characters were to animate, and as visually interesting as their society was, [[UnintentionallyUnsympathetic it was very difficult to like or relate to them as characters]] because of how they treated the robots on the Axiom, their bizarre made up language, and the fact that they were distracting the audience from WALL•E & EVE's story. The blobs were changed to fat "big baby" humans and made more to seem like they were [[LotusEaterMachine distracted by the ship they lived on]]. Also, the Captain [=McCrea=] was made smarter and more like his life was unchallenged rather than he was actually dumb. This made it much easier for audiences to connect with them and helped serve WALL•E & EVE's story.
** In the original cut, WALL•E and EVE's roles in the garbage airlock were reversed so that [[spoiler:EVE was the one who was shocked by AUTO, and WALL•E had to come to her rescue and fix her]]. However, Andrew Stanton found himself highly dissatisfied with the scene because of how disconnected it was from the rest of the film, and felt that swapping their roles would simultaneously showcase EVE's CharacterDevelopment and raise the stakes of the final act. Mind you, this decision came about during a pre-release film screening in Portland, meaning the movie was practically finished before the change was made at the last minute, ''narrowly'' putting this trope into effect. The tie-in games, [[EarlyDraftTieIn being developed before this change]], retains their original roles.
** When [[spoiler: WALL•E's body falls out of the Holo-Detector, the original plan was that he'd be leaking oil, and if the storyboards are any indication, he'd eventually be lying in a small pool of it.]] This detail is present in the junior novelizations, storyboards, and scripts. It's likely it was removed because it looked [[DoesThisRemindYouOfAnything a little too much like]] [[MachineBlood something else]]. There's also the fact that WALL•E was only shown relying on solar power, so it wouldn't have made much sense.
** Auto was once a typical moving droid rather than the steering wheel of the ship.
** According to the commentary, the ''Film/HelloDolly'' songs were originally generic French cabaret music. Then Andrew Stanton recalled that [[WesternAnimation/FindingNemo his previous film]] had beaten out [[WesternAnimation/TheTripletsOfBelleville a French film with a cabaret soundtrack]], which he'd recently watched and become a fan of, for the "Best Animated Feature" Oscar and decided against it so as not to come across as a sore winner.
** In addition to "Put On Your Sunday Clothes" and "It Only Takes a Moment", one more song from ''Hello, Dolly!'' was considered for inclusion: "Dancing", for the scene where Wall-E and [=EVE=] race around the outside of the AXIOM.
* WorkingTitle: In development, this film was known as "Trash Planet".

!!Misc. Trivia
* ''WALL•E'' is the first film to start production and be released past the end of the original distribution agreement between Disney and Pixar. This agreement was extended to ''WesternAnimation/{{Ratatouille}}'', but Disney's purchase of Pixar invalidated it immediately.
* This is the first new Pixar film to use the new standard 2006 Walt Disney Pictures VanityPlate with the excerpt of ''WesternAnimation/{{Pinocchio}}'s'' "When You Wish Upon A Star" in place of the custom Walt Disney Pictures logo with the sky-blue background and an unique fanfare composed by Music/RandyNewman.
* The follow-up DVD/Blu-ray release was the second-highest selling animated DVD and the third highest-selling DVD period of 2008. This specific DVD is the first Pixar DVD (in the US at least; internationally, ''Ratatouille'' was the first) to use the [[WesternAnimation/PeterPan Tinker Bell Disney DVD]] logo prior to the film; all [=DVDs=] between the 2000 releases of the first two ''Toy Story'' films (which used the 1992 Gold Walt Disney Home Video logo) and this one had no Disney DVD logo on them.
* ''WALL•E'' was inducted into the UsefulNotes/NationalFilmRegistry in 2021, making it the second Pixar film inducted after ''WesternAnimation/ToyStory1'' in 2005.
* In November 2022, Creator/TheCriterionCollection released a 4K Blu-Ray edition of this film, making it - as Criterion proudly noted in their press release - the Collection's first Pixar film, first Disney-backed animated feature and first Disney-branded feature[[note]]prior Criterion titles licensed from Disney came from the libraries of Creator/TouchstonePictures, Creator/TwentiethCenturyStudios and the Creator/{{ABC}}, as well as their first and now out-of-print Blu-ray of ''Film/ChungkingExpress'' in 2008 being licensed from the then-Disney-owned Creator/{{Miramax}}[[/note]].
