* ActorAllusion:
** Puss, played by Creator/AntonioBanderas, ''is'' Zorro as a cat - right down to the trademark letter-carved-on-a-tree.
** In ''Shrek the Third'', listen to the queen's NonSequiturThud after [[spoiler:she head-butts the wall apart]]. Sound familiar? [[spoiler:It's a bit of "A Spoonful of Sugar" and "My Favorite Things".]]
** King Harold makes a excuse about his old "crusade wound" acting up. As [[Series/FawltyTowers Basil Fawlty]], Creator/JohnCleese made a similar claim about an old war wound.
*** Surely, 'twas [[Film/MontyPythonAndTheHolyGrail only a flesh wound?]]
*** This also isn't the first time that Cleese has played [[spoiler:[[WesternAnimation/TheSwanPrincess a frog in an animated film]]]].
** Surely Creator/MikeMyers as [[Film/AustinPowers a big guy with a Scottish accent]] counts; ''Shrek Forever After'' even has [[StealthPun Fiona mistakenly calling him "Scott"]].
** Shrek cracks a mirror by looking into it and smiling: the scene is [[IncrediblyLamePun virtually]] identical to the same one featured in Mike Myers' ''Film/AustinPowers'' films.
** Donkey's line "I had my mouth open and everything" actually came from part of Creator/EddieMurphy's "Delirious" routine.
*** And the line "I'm a donkey on the edge!" may be a reference to ''Film/FortyEightHours'':
-->"I am your worst nightmare! ''A nigga with a badge!''"
** In the fourth movie, Donkey very poorly sings the final line of Music/WhitneyHouston's "Greatest Love Of All", a reference to Eddie Murphy's role as the incredibly untalented Randy Watson in ''Film/ComingToAmerica''.
** Shrek tells Donkey "You're going the right way for a smacked bottom". Film/AustinPowers said the exact same thing to Music/{{Madonna}} in the ''Beautiful Stranger'' video.
** Donkey bragging about how he's [[Film/TheNuttyProfessor "the stairmaster"]].
%%Explain how this is an ActorAllusion.
%%** And how have not mentioned Shrek:
%%*** Having a Scottish accent
%%*** Being accused of eating his own children
%%*** Boasting about how his bowel movements could kill a donkey
%%*** Taking physical abuse first in his backside, then in his gonads.
* AFIS10Top10:
** #8, Animation
* AscendedMeme: A fanon interpretation of Donkey is that waffles are his favorite food. In the Swamp Talk videos on the [=DreamWorks=] TV Website/YouTube channel, he does say stuff that allude to that being canon.
* {{Blooper}}: In ''Shrek 2'', when Fiona knocks out Prince Charming with a headbutt, he's seen seconds later perfectly fine throwing the wand to the Fairy Godmother. You could argue that he recovered quickly, but then a few minutes later, he's seen getting up from the headbutt.
* CashCowFranchise: In the top 10 for "Highest grossing movie franchises of all time" list.
* CelebrityVoiceActor: The four main characters were played by Creator/MikeMyers, Creator/CameronDiaz, Creator/EddieMurphy, and Creator/JohnLithgow - all of whom were BilledAboveTheTitle. Creator/JimCummings, who has a relatively prominent role as the Captain of the Guard, is the only voice actor by profession to appear in the film.
** The Japanese dub of all the films raises this angle UpToEleven, as it will be easier to say ''which'' voice actors aren't this.[[note]]Creator/KoichiYamadera as Donkey, Creator/NobuoTobita as Pinocchio, Creator/KenjiUtsumi as the Big Bad Wolf, Creator/HiroYuki as Gingy, Creator/UnshoIshizuka as Prince Charming, Creator/TakeshiAono as King Harold, Toshiko Sawada as Queen Lillian, Creator/WataruTakagi as the Three Blind Mice, Creator/TesshoGenda as Mabel and Brogan, plus many other voice actors who voice minor roles.[[/note]]
* CreatorKiller: One of the franchise's sources of fuel was all the snark, bitterness and derision directed towards Creator/{{Disney}} boss and Katzenberg's former superior Michael Eisner, including having Farquaad be a caricature of him; this movie was one of the multiple punches that eventually knocked Eisner out of the Mouse House in 2005 (nearly losing Creator/{{Pixar}} was the final punch to send him to the floor).
* CrossDressingVoices: Gingy is puppeteered and voiced by a woman in each production. Averted in foreign dubs.
* DeletedScene: One from the first film has Fiona meeting a Gypsy woman named Bib Fortuna (a reference to the ''Franchise/StarWars'' character of the same name), who would eventually become the FairyGodmother. In this version Fiona is ''always'' an ogre, and Bib Fortuna gives her a potion that would make her beautiful, but tells her that she will alternate between her human and ogress forms until she finds true love. After that, she is whisked away by her dragon guardian and returned to the tower.
** Also, Wiki/TheOtherWiki says that the filmmakers intended to show the "Happily Ever After"-Form of Dragon as a pink winged Mare in ''Shrek 2''. They decided against it.
** There was going to be a scene shortly after Shrek and Donkey get Fiona out of the dragon's keep that would involve them riding a mine cart like a roller coaster, complete with at least three references to Disneyland via the talking skull from Pirates of the Caribbean, the yeti from Matterhorn Bobsleds, and the Country Bears. The storyboards for this scene are included in the DVD.
** After Shrek won the tournament in the first film, there was to be a scene where Farquaad explains the quest to Shrek and they're standing side-by-side to show their size comparison ([[AdaptationInducedPlotHole explaining Shrek and Donkey's size jokes to Fiona later in the film]]). One was storyboard which Farquaad wish to turn Duloc into a more modern city with convenient stores and mini-malls.
* FollowTheLeader: Several other {{fractured fairytale}}- based films, such as ''WesternAnimation/{{Hoodwinked}}'', ''Disney/ChickenLittle'' and ''WesternAnimation/HappilyNeverAfter''.
** It's difficult to imagine just how influential and popular ''Shrek'' was when it first came out, as just about every western animated feature has been influenced by its humor and style, not to mention "proving" that computer animation was the only way to go in the 21st century.
* GenreKiller: After the first film became a roaring success, it would take nearly a decade for non-ironic fairy tale movies, especially ones made by Disney, to be taken seriously again. It didn't help that, in the decade preceding ''Shrek'', Disney had done nothing but blockbuster princess musicals following the box office underperformance of ''Disney/TheRescuersDownUnder'' (which Katzenberg oversaw) and some of Disney's staff were losing interest in it at that point themselves, as evidenced by ''Disney/TheEmperorsNewGroove'' being a full-blown comedy and ''Disney/AtlantisTheLostEmpire'' being an adventure film.
** Along with Creator/BlueSkyStudios' ''WesternAnimation/IceAge'', another hugely successful non-Disney CGI film, this film became the final nail in the coffin for traditional feature animation in America. Disney shooting themselves in the foot in their attempts to revive it then and later by putting those movies against guaranteed blockbusters didn't help.

* TheOtherDarrin: Dean Edwards replaced Creator/EddieMurphy as Donkey in ''Scared Shrekless''. Murphy replaced Edwards for ''Donkey's Christmas Shrek-tacular''.
* TheOtherMarty: Creator/ChrisFarley was attached to ''Shrek'' early in its development, but after his death (and many story changes) the role went to Mike Myers, who then performed an odd same-actor version of this trope, switching to a Scottish accent partway through and re-recording already-done lines.
* PermanentPlaceholder: According to WordOfGod, the use of the Music/SmashMouth song "All-Star" at the beginning of the first movie was only intended as test footage track to get the timing of the opening down - they planned to use an original composition for the final product. However, "All-Star" worked so well that they kept it in.
* ThrowItIn:
** The line "You're on your way to a smacked bottom" was improvised by Creator/MikeMyers after he got annoyed at one of the directors.
** The scene where Princess Fiona burps was written after Creator/CameronDiaz burped during a recording session after drinking Coca-Cola.
* UnintentionalPeriodPiece: The movie's soundtrack features Music/SmashMouth and Music/TheBahaMen, and it stars Creator/MikeMyers and Creator/EddieMurphy, two men whose careers have cooled off considerably since the movie came out.
* WhatCouldHaveBeen:
** The film was originally going to be produced by Creator/StevenSpielberg, be hand-drawn, and star Creator/BillMurray as Shrek and Creator/SteveMartin as Donkey. Spielberg did however still serve as the executive producer for the film, albeit going uncredited.
** The original script had Princess Fiona born an ogre to the late King and Queen of Duloc. They had her locked in the tower under the lie that she was "of such rare beauty" she was kidnapped. They died, and the kingdom was left under the rule of an ambitious regent (implied to be Farquaad). When she 'became of age' to ascend the throne she escaped the tower and encounters a witch named Bib Fortuna (a reference to the ''Star Wars'' character of the same name) - who has narrated the entire sequence through her tarot cards. She gave Fiona a potion which would make her beautiful; but Fortuna warns her the potion has a side effect - she will change between her human and ogress form until she finds her true love. Later she was whisked away by her dragon guardian and returned to the tower. This storyline was not adapted to keep the story simple, but is mentioned through the "witch" Fiona tells Donkey about.
** Chris Farley was originally cast as Shrek and even recorded part of the dialogue. When Farley died, another ''SNL'' cast member got his part (Mike Myers). Farley's lines prior to his death can be [[https://www.youtube.com/watch?v=IcqJgC0WZ3o found here]].
** Creator/JaneaneGarofalo was originally going to voice Fiona, but with the recasting of Shrek's voice actor, Fiona's voice and character were changed so she could contrast with Shrek better.
** Music/PaulMcCartney originally was in talks to voice Rumplestiltskin, even going as far as having a musical number for him planned with a song written by [=McCartney=] himself.
** In the first movie, they wanted the crescent moon on Shrek's outhouse to be the [=DreamWorks=] logo moon. [[ExecutiveVeto But the studio said no.]]
** Shrek originally looked [[http://screencrush.com/files/2012/08/shrek-early-concept-art.jpg quite goofy]] (it's the picture on the right).
* TheWikiRule: [[http://shrek.wikia.com/wiki/WikiShrek The Shrek Wiki]].
* WriterRevolt: Well, ''producer'' revolt. Former Disney CEO Jeffrey Katzenberg made this film as a great big "Screw you!" to his previous company and especially his former partner Michael Eisner, whom he loathed, after Eisner shot down many of Katzenberg's idea and later beat him out of the studio head position. It worked, seeing as how this film put [=DreamWorks=] on the map and ended up indirectly contributing to Eisner being let go by Disney.
