* AlternateCharacterInterpretation: The Girl who rescues Dorothy at the Beginning [[spoiler: whom Dorothy sees as Ozma at the end]]. Is she just [[spoiler: Ozma's real world counterpart]] like how the other characters are, and if so did she drown? Is she [[spoiler: Ozma's soul]] reaching out to Dorothy, thus making her the same character? Or is she [[spoiler: Ozma's soul]] appearing to her as a figment of her imagination, as she get's into closed rooms, and the Doctors never seem to acknowledge her? If that's the case, can she interact with the real world in a limited capacity, seeing as she untied Dorothy, or was that also imagined, and she just wasn't tied in well?
* CompleteMonster: [[VainSorceress Princess Mombi]] is a deranged, tyrannical sorceress who usurped control of the Emerald City by trapping the true ruler inside an enchanted mirror. A {{narcissist}} whose looks are fading with age, Mombi [[OffWithHerHead collects the heads of beautiful women]] and [[SwissArmyAppendage swaps her own head for one of theirs]] every so often. When not in use, the heads are [[AndIMustScream kept alive and conscious]]. When Dorothy arrives in the Emerald City, Mombi has her imprisoned with the intention of adding her head to her collection once she becomes an adult.
* CrowningMusicOfAwesome: The whole soundtrack can go from eerie to sad or magnificent, and sprouts a wide variety of music, going from orchestra to silent era piano to a creepy mandolin or a modern techno for the Nome King.
* CultClassic
* HellIsThatNoise: The Wheelers's laughs and ''especially'' the squeaking sounds they make when they roll around.
* HilariousInHindsight: Or a FunnyAneurysmMoment depending. The nome hands reaching out to pull open a passageway to the Nome King's ornament room rather resembles a certain well-known shock site.
** Before that, the Nome King was serving [[WesternAnimation/MyLittlePonyFriendshipIsMagic limestone pie]].
* GermansLoveDavidHasselhoff: The film did well in Japan, possibly because they marketed toward its dark side.
* {{Narm}}: The Nome telling the Nome King that Dorothy has [[spoiler: '''A CHICKEN!!''']]
** The Nome King rising up gigantic and surrounded with flames as the embodiment of satanic evil and the first line that comes out of his mouth sounds like "S'UP!!!" in a deep rumbling voice (he's actually saying "STOP!!!").
** Additionally him revealing that he has the Ruby Slippers. Yep the BigBad king revealing he's wearing a pair of glittery red high heels.
* NarmCharm: Tik-Tok hugging Dorothy and [[TearsFromAStone shedding green oil tears]] should be ridiculous. [[TearJerker It isn't.]]
* RetroactiveRecognition: Creator/FairuzaBalk is Dorothy.
* StrawmanHasAPoint: The Nome King points out that as the precious stones of the world are made and owned by Nomes, those humans who mined and used them are actually guilty of theft. True, it doesn't actually excuse him for invading Oz just to retrieve the Emeralds and turning the inhabitants to stone, but still...
** Apparently diplomacy and negotiating went right out the door when he became king.
* TearJerker: The end credits and ending in general have a very sad tone, even with the happy ending.
* UglyCute: Jack Pumpkinhead.
* WhatDoYouMeanItsForKids: The film is meant to be seen as a kids' adventure film, yet there are the infamous scenes such as shock therapy, the disembodied heads of the Lollipop Guild, and of course, the Nome King.
* TheWoobie: Dorothy and Jack.
