History Film / TheVoyageOfTheDawnTreader

* AdaptationSpeciesChange: A partial one. Lilliandil is portrayed as being a full-blown star like her father Ramandu. In the book, she did not glow like her father, did not change form, and was implicitly half-human through her unmentioned mother. The description of her in ''Literature/TheSilverChair'' simply said that "the blood of the stars flowed in her veins" rather than that she was one.

* BallOfLightTransformation: Lilliandil, Ramandu's daughter, falls from the sky as a blue star before taking human form. Then she rises up again in the same shape. It's implied, though, that the star is her true form and that she could take any she wish.

** Lucy's jealousy of Susan's beauty is expanded. In the book, she almost reads the spell to become beautiful beyond the lot of mortals so that she'll eclipse her sister but is stopped by Aslan at the last minute. Here, she steals the spell and reads it later on the boat, getting a huge nightmare sequence where she imagines that she has ''become'' Susan, Lucy never existed, and her siblings never heard of Narnia because Lucy wasn't there to find the passage through the wardrobe. Aslan then appears in her dream to admonish her.

** Lucy's jealousy of Susan's beauty is expanded. In the book, she almost reads the spell to become more beautiful than her sister but is stopped by Aslan at the last minute. Here, she steals the spell and reads it later on the boat, getting a huge nightmare sequence where she imagines that she ''is'' Susan, Lucy never existed, and her siblings never heard of Narnia because Lucy wasn't there to find the passage through the wardrobe. Aslan then appears in her dream to admonish her.

** In the book, Ramandu's daughter only appears at Aslan's Table. Here she is foreshadowed as the Blue Star that guides the sailors to the various islands and serves to warn them about the Dark Island. She also gains a (rather [[Creator/JRRTolkien Tolkien]]-sounding) name, Liliandil.

** Ramandu, despite being mentioned a few times, never actually appears in the movie.

** The Minotaur Tavros and the faun crewmen were also created for the movie as the book had an all human crew with the exception of Reepicheep.

* NeverTrustATrailer: See MissingTrailerScene, which was there to give the impression that the two older Pevensie children feature in the plot too. Additionally the trailer made a point of showing the White Witch's cameo - which Tilda Swinton herself expressed surprise about.
* NiceJobBreakingItHero: Just as the heroes are about to escape the Dark Island, Lord Rhoop basically tells them "Whatever you do, don't think about the thing you fear most." Though in all honesty, if he's been trapped there fearing for his life for an indeterminate amount of time, no doubt his reasoning and sanity have degraded from what they were.
* NotEvenBotheringWithTheAccent: Caspian lost his Telmarine (i.e. Hispanic) accent between films 2 and 3. Although this may just reflect the fact that he's been King of Narnia for a good few years and has simply picked up the natives' (very British) accents, or even emulated them on purpose as a gesture of solidarity. After all, he is a ''Telmarine'' king. WordOfGod [[https://www.quora.com/Why-does-Prince-Caspians-accent-change-between-the-second-and-third-movies was]] that it was because it was a different take on the character with a new studio and new director, and since C.S. Lewis was a British writer, they would no longer use that accent.
* TheNotLoveInterest: Edmund and Lucy become this, as they constantly look for one another and [[CallMyName desperately call each other's name]] when they are separated. Edmund and Caspian have some elements of this as well as they become like brothers, but their friendship always takes a backseat to Edmund's concern and care for Lucy, when his BigBrotherInstinct kicks in. Basically, Lucy is the most important person to Edmund, as his first priority is to take care of her and keep her safe. The same for Lucy, who constantly looks for her brother.
* NotQuiteDead: [[spoiler: Eustace. Edmund and Caspian find his charred clothes and thought he died. He didn't]].
* OurMermaidsAreDifferent: In the beginning of the film, Lucy meets a group of aquatic beings in the ocean as she did near the end of the book. However the film replaces the ivory skinned, purple haired Sea People with naiads. While naiads where mentioned in the book versions of the first two films, they were omitted almost entirely save for the River God in the second film. The film naiads are basically similar to the mermaids that appeared near the end of the first film, except instead of being made of flesh, blood, bone, and scale like traditional mermaids, they are made entirely of non-dissolving liquid. The books and classical mythology state that naiads are fresh water nymphs and salt water nymphs are nereids and oceanids. The books and mythology also NEVER state that water nymphs have fish tails. Also falls under SadlyMythtaken.

** The film's main plot, about the mist of evil and gathering the swords, has no basis in the book series at all. On the other hand, the mist and swords help to tie everything together - the original book was a series of short stories tied together by the eponymous boat, the same characters, and the fact that they were trying to find the seven Lords. With the addition of the mist, it gave the story a kind of nebulous BigBad of a sort.
** The naiads. Naked sea people probably wouldn't fly in a family film these days.

** His eventual reversion is still painful ("like when you pull a thorn from your foot"), but Aslan removing his dragon-skin via FullContactMagic is much less physically disturbing than in the book where Aslan literally ''peels off'' Eustace's dragon-form with his claws.

** [[AvertedTrope Averted]] when the Dufflepuds come to get Lucy to recite the spell to make them visible (only a girl or the book's owner can cause the spell to work). One of them notes that [[TagAlongKid Gael]], a CanonForeigner, is also a girl. However, the Dufflepuds then note that Lucy has a book next to her, indicating that she knows how to read, justifying why they specifically kidnap Lucy like in the book.

** Gael Rhince's daughter, who isn't in the book. In a sense she acts as someone for Lucy to be a big sister to, having spent two films as the baby of the group.

** In the book, Ramandu's daughter only appears at Aslan's Table. Here she is foreshadowed as the Blue Star that guides the sailors to the various islands and serves to warn them about the Dark Island. She also gains a name.

** The seven Lords having swords associated with Aslan. At the time when they set sail, Aslan was known only as a myth believed by fantastical creatures and as a likely enemy to Telmarines like them.

However, the Dufflepuds then note that Lucy has a book next to her, indicating that she knows how to read, and kidnap her.

* AdaptationalContextChange: In the book, Caspian's desire to travel to the end of the world is treated as grossly irresponsible with everyone calling him out for shirking his responsibilities as king. In the movie no one has a problem with it.

** Ramandu's daughter only appears at Aslan's Table. Here she is foreshadowed as the Blue Star that guides the sailors to the various islands and serves to warn them about the Dark Island. She also gains a name.

* HiddenAgendaVillain / OutsideContextProblem: It's never really stated who or what the Mist is, or what it wants. [[spoiler: It is rather explicitly ''green''... which means it may be clever Foreshadowing for the Lady of the Green Kirtle/the Emerald Witch of ''The Silver Chair'', the next installment of the Chronicles. Which, in turn, would turn the sea serpent into a bit of foreshadowing as well. It's confirmed by WordOfGod that The Lady of the Green Kirtle is behind the green mist]].

* WolverinePublicity: Much like the last film, the trailer gives the impression that the White Witch is a villain in this film. (To a certain extent she is, at least as far as Edmund is concerned. And you can't help but wonder how many times Edmund has to smack her down before she gets the message and stops trying to tempt him.)

* AscendedExtra: [[spoiler: The sea serpent]].

* AsskickingLeadsToLeasership: Kings Edmund and Caspian are both extremely proficient swordsmen, and Lucy's not half-bad herself.

* AuthorityEqualsAsskicking: Kings Edmund and Caspian are both extremely proficient swordsmen, and Lucy's not half-bad herself.

** Lucy's jealousy of Susan's beauty is expanded. In the book she almost reads the spell to become more beautiful than Susan but is stopped by Aslan at the last minute. Here she steals the spell to replace Susan and reads it later on the boat, getting a huge nightmare sequence where she imagines that she is Susan, Lucy never existed, and her siblings never heard of Narnia because Lucy wasn't there to find the passage through the wardrobe.
** The argument at the Deathwater Island was just a random incident in the book, and implied to be partly the result of a sinister magical influence. In the film it's the escalation of a lot of conflict that's been building up for a while.
** Eustace has his epiphany and is turned back from being a dragon before they've even left the island. Here he doesn't get turned back until the end.

** Peter Pevensie's whereabouts are unmentioned outside of Lucy referencing him and Susan being on adventures. The book explains he was staying with Professor Kirke to study for an exam, and that due to the Professor's reduced circumstances Edmund and Lucy were unable to join him.

** In the book, Lucy finds a spell in Coriakin's house that will help her hear what her friends say about her. She uses it and then witnesses a friend being pressured into saying nasty things about her. Aslan later scolds her for this, and tells her that the friend did not mean the things she said. The book also shows her what would happen if she used another spell that would make her "beautiful beyond the lot of mortals". In the movie this is replaced with the Susan nightmare sequence.

** [[spoiler:Lucy secretly isn't happy with herself and she envies her older sister's beauty and life to the point that she wishes she had her sister's life]]. She gets better.

* DreamWithinADream: Lucy dreams that she is Susan and that she is in the USA with her ''only'' two siblings, Peter and Edmund. She wakes up from this dream to have Aslan appearing in a mirror and talking to her. Then she wakes up from this dream- and is now awake in Narnia.

** In the scene when Lucy has Susan's body, the first person she sees is Edmund who walks with her arm in arm saying "''You're beautiful, sister''". And Peter even joins them.
* InformedAttractiveness: Lucy is jealous of Susan's beauty. Then again this is mostly a case of sibling rivalry so it's justified either way. It's more to do with Susan being taken to America and having boys chasing her. Lucy just assumes it's because of Susan's looks.

* WhatHappenedToTheMouse: Given some AdaptationExpansion here. In the book, the fate of Lord Octesian is left unclear, although he presumably died on Dragon Island; in the film Eustace finds his skeleton.

* AffirmativeActionGirl: Gael, who isn't in the book. In a sense she acts as someone for Lucy to be a big sister to, having spent two films as the baby of the group.

** Why Lord Bern stayed in the Lone Islands is never explained. In the book, he fell in love and decided to settle down there.

** The seven Lords having swords associated with Aslan. At the time when they set sail, Aslan was known only as a myth believed by fantastical creatures and as a likely enemy to Telmarines like they.

* {{Xenafication}}: As with Susan in the other movies, and ''Prince Caspian'' especially, Lucy is now far more violent than in the book.

* MissingTrailerScene: The trailer showed a couple of shots of Peter and Susan in Narnian clothing with weapons over their shoulders.

** Lucy's jealousy of Susan's beauty is expanded. In the book she almost reads the spell but is stopped by Aslan at the last minute. Here she steals the spell and reads it later on the boat, getting a huge nightmare sequence where she imagines that she is Susan, Lucy never existed, and her siblings never heard of Narnia.

* AdaptedOut: In Corialkin's house, Lucy finds a spell that will help her hear what her friends say about her. She uses it and then witnesses a friend saying nasty things about her. Aslan later scolds her for this, and tells her that the friend did not mean the things she said. In the movie this is replaced with the Susan nightmare sequence.

* MrExposition: Corialkin helpfully explains a lot of things about their quest.

* BehemothBattle: There is a brief one between Eustice in Dragon-form and a Sea serpent.
%% * BeYourself: Somewhat [[{{anvilicious}} anviliciously]].

* ALoadOfBull: There are a couple of minotaurs in the film, one of them looks more like a goat rather than a bull.
