* AbilityOverAppearance:
** Lucy in the book is blonde. Creator/GeorgieHenley is brunette but captures Lucy perfectly. The two boys' hair colours are never mentioned, but the original illustrations and previous adaptations have Peter brunet and Edmund blond -- this is inverted in the film. The only Pevensie to keep the same hair colour is Susan.
** Jadis is also commonly depicted with black hair -- and she was going to be in this. However, they changed it to blonde so as not to make her look too gothic. Creator/TildaSwinton received unanimous critical praise for her performance.
* ActingForTwo: The 2022 West End adaptation features plenty of double casting due to the wide variety of characters spanning across the two worlds. Samantha Womack plays both Mrs. Macready and the White Witch; Johnson Willis plays both Professor Kirke and Santa, as well as a few Narnians. Though Aslan doesn't show up until Act II, Chris Jared plays a few different characters in Act I, such as a soldier and a Narnian creature.
* ActorInspiredElement: The Pevensies being from Finchley was added in because Anna Popplewell (Susan) is from there.
** Similarly, the Pevensies’ mother was named Helen after Lucy portrayer Georgie Henley’s mother.
* AdaptationOverdosed: Has received plenty of adaptations, especially stage ones, and is a popular choice for local theatres especially around the holidays. Most notably, a new major production opened in the West End of London in 2022.
* AwesomeDearBoy: Jadis is one of Creator/TildaSwinton's favourite roles to play and she reprised it in the subsequent films - even when the character didn't actually appear in the books[[note]]In ''Prince Caspian'' some characters talk about resurrecting her; in the film they partially succeed. In ''Voyage of the Dawn Treader'' an apparition of her appears to prey on Edmund's fears[[/note]]. She likewise expressed excitement at getting to play her in a potential film of ''The Magician's Nephew''.
* CaliforniaDoubling: New Zealand doubled for Narnia, London and Professor Kirke's country estate. The Czech Republic, Poland and Slovenia also filled in for other parts of Narnia.
* CastTheExpert: The 2022 West End production of the stage adaptation is an actor-musician show, where the cast also doubles as the orchestra. When not their main role, several actors also provide musical accompaniment as Narnian creatures.
** In addition, experienced puppeteers (who also had to know how to sing, dance, act, and/or play instruments) were cast in order to bring Aslan to life.
* CastTheRunnerUp: Peter looks at a World War II soldier walking through the train station for no apparent reason. This soldier is played by Jaxin Hall, the runner-up for the role of Peter.
* CelebrityVoiceActor: The animal characters are all voiced by these - Creator/LiamNeeson as Aslan, Creator/RayWinstone as Beaver, Creator/DawnFrench as Mrs Beaver, Creator/RupertEverett as Fox and Creator/MichaelMadsen as Maugrim.
* {{Corpsing}}: The reaction shot of Peter to Aslan's "Beaver mentioned you planned on turning him into a hat" wasn't in the script. A fly was buzzing around Creator/WilliamMoseley's head and he couldn't stop grinning.
* DescendedCreator: Edmund's horse Philip is voiced by producer [[TheDanza Philip Steuer]].
* EnforcedMethodActing:
** In the Walden film, Tilda Swinton (White Witch) flirted with Skandar Keyes (Edmund) to make him feel more uneasy for their scenes together.
** The entire film was shot in near-chronological order - so that the characters' emotional growth would be reflected by the physical growth of the actors. The obvious exception is the scene of [[spoiler: all four falling out of the wardrobe at the end]].
** Creator/GeorgieHenley was brought onto the set blindfolded when filming Lucy's first arrival in Narnia. As such her reactions to the wood are genuine. Likewise she hadn't seen Creator/JamesMcAvoy in his costume before filming the scene, so her reaction to Mr Tumnus is genuine too.
** Creator/SkandarKeynes likewise wasn't shown the set beforehand, so Edmund's reaction to Narnia is his own as well.
** Edmund was the last of the children to be cast, so the other three actors were already familiar with each other by the time Skandar Keynes was brought in. As such this adds to the detachment between him and the others. Also Skandar Keynes hates being hugged, so the director had the others {{Glomp}} him at every possible opportunity to drum up the animosity.
** Creator/AnnaPopplewell got Creator/GeorgieHenley to cry for the Stone Table scene by shouting at her.
* ExecutiveMeddling: Lewis was dead when the books were re-ordered. He had no intentions of re-ordering the story himself, his only public expression on the order of the books being a simple letter to a child telling him to read them in whatever order he thought best.
** From the first chapter it’s clear that this book is meant to be read first: if you’ve already read “The Magician’s Nephew” and know the wardrobe was made of wood that came from a magical tree in Narnia, then the surprise of Lucy opening the wardrobe and finding a portal is greatly reduced.
* ExtremelyLengthyCreation: After the series was concluded, Lewis wrote an essay revealing that he had had the image of a Faun carrying an umbrella and parcels in a snowy forest since he had been about sixteen, then later decided to try to make a story out of it when he was about forty (though this first attempt was quickly abandoned), before finally completing the book when he was was fifty.
* FakeAmerican: New Zealand actor Patrick Kake puts on an American accent to play the centaur Oreius.
* FakeBrit:
** Aslan is voiced by Northern Irish actor Creator/LiamNeeson, who tones down his accent to sound more English.
** Creator/JamesMcAvoy goes for an English accent instead of his natural Scottish to play Mr Tumnus.
** Creator/JamesCosmo (Father Christmas) likewise is Scottish but gives him an English accent.
** A few New Zealand locals affect English accents to play featured extras in Narnia.
* FakeIrish: Mrs Macready is given an Irish accent but is played by New Zealand actress Elizabeth Hawthorne.
* FollowTheLeader: The films were greenlit as soon as ''Film/TheLordOfTheRings'' and ''Film/HarryPotter'' became successes.
* ProductionPosse: The 2022 West End production of the stage adaptation is helmed and directed by Michael Fentiman, who brought on several collaborators from one of his previous shows, ''Theatre/{{Amelie}}'', following its limited West End run; creatives and cast include composer Barnaby Race, Robyn Sinclair (Cecile) as Susan, Jez Unwin (Raphael) as Tumnus, and Chris Jared (Nino) as Aslan.
* RealLifeRelative:
** Georgie Henley's older sister Rachel plays the adult Lucy at the end.
** Skandar Keynes's voice had broken during filming, so his [[CrossCastRole sister]] [[CrossDressingVoices re-dubbed]] some of his dialogue. That is why Edmund sometimes sounds a bit “dolls and dresses”.

--> '''[[cinnamon:Okiku]]:''' [[gray:(It's an absolutely normal wardrobe.)\\
(It's not like it's a portal to another dimension, or whatever!)\\
(Though, that would be pretty neat!)]]
* RemakeCameo: On the train, the two children sharing a compartment with the Pevensies are the children of Creator/SophieCook - who played Susan in the BBC adaptations.
* SavedFromDevelopmentHell: The film took forever to get picked up primarily because of the British setting. Producers felt they would need to relocate the story to America - quite difficult when the setting involves BlitzEvacuees. Then when ''Film/HarryPotter'' proved a success, setting the films in the UK was no longer a problem. Douglas Gresham had also opposed adapting the books again because he had hated the BBC adaptations featuring the animals played by actors in animal costumes - and didn't sign over the rights until he saw models of the animals created with CGI.
* ScullyBox: Creator/TildaSwinton -- already a StatuesqueStunner at 5"10 -- wore platform shoes to make herself seem taller and more intimidating than the children. Her character is half giant, after all.
* ThrowItIn:
** Creator/GeorgieHenley ad-libbed "My mother's name is Helen" when she meets Mr Tumnus. Notably the Pevensie mother wasn't given a name in the original books - making this a case of NamedByTheAdaptation (Helen being Georgie Henley's mother's name).
** The young soldier that Peter looks at in the train station is Creator/JaxinHall - who was the runner-up for the part. He was given this cameo as a consolation prize.
* WhatCouldHaveBeen:
** Early in pre-production, producers wanted to set the film in modern times and make the Pevensies American. Instead of being BlitzEvacuees, they would have stayed with the Professor because their home was destroyed in an earthquake, and the Witch's Turkish Delight would have been replaced with a cheeseburger and fries. Douglas Gresham opposed all that, resulting in Andrew Adamson's more faithful adaptation.
** Creator/GerardButler was originally going to voice Aslan, but when he auditioned for it, he asked "This isn't going to be like the BBC puppet Aslan, right? Because, if so, I'm leaving right now". Creator/SeanConnery, Creator/BrianCox and Creator/RussellCrowe were also considered.
** Creator/NicoleKidman, Creator/MichellePfeiffer, and Creator/KateWinslet were considered for Jadis the White Witch.
** Creator/GuillermoDelToro turned down the chance to direct because, as a lapsed Catholic, he couldn't see himself bringing Aslan back to life. Creator/MNightShyamalan was also offered the job, but declined.
** As said above, Jadis was going to have long black hair. However the director felt that looked too gothic and they went for a LightIsNotGood approach.
** Amy Lee from {{Music/Evanescence}} wrote a song for the film, but it wasn't included in the soundtrack.
* WordOfGod: Several readers (and their parents) wrote to Creator/CSLewis to ask what happened to the animals at the dinner party who were turned to stone by the Witch for refusing to lie about their having met Father Christmas. He always replied that Aslan did eventually get around to turning them back after the battle, and that he was sorry that his readers were distressed by [[WhatHappenedToTheMouse not knowing what happened to them]].
* WorkingTitle: The movie had two fake working titles: ''The Hundred Year Winter'' and ''Paravel''. Signs in Auckland that directed extras and crew to the sets had "Paravel" written on them.
