- Alternate Character Interpretation:
- The film adds the possibility that Susan's eventual denial of Narnia is due to the romance that could never happen with Caspian.
- In contrast to her stance as Queen Susan the Gentle, do Susan's rather aggressive tendencies on the battlefield come from somewhere else? She ruled as a Queen for fifteen years in what appears to be a progressive society - and then had to return to 1940s England where women were still in Stay in the Kitchen roles. That's bound to make her long for the power and freedom she once had. Likewise women did serve roles in the war, but Susan as a teenage girl probably wouldn't be able to - thus frustrating her even more.
- Author's Saving Throw: The Telmarines become a Fantasy Counterpart Culture of Mediterranean cultures - Word of God wanting to emphasise their pirate origins. In order to avoid Always Chaotic Evil, Prunaprismia and Glozelle are given Adaptational Heroism.
- Awesome Music: Regina Spektor 's "The Call" at the end of the movie.
- Big-Lipped Alligator Moment: Susan and Lucy partying with Bacchus while the boys rescue Caspian. It has no impact on the plot, the mythology crossover is never explained, and it's never mentioned again.
- Broken Base:
- The Caspian and Susan romance. Some invoke They Changed It, Now It Sucks! and Strangled by the Red String. Others were happy Susan had something to actually do in the film (as she did very little in the book) and liked the foreshadowing to her eventual fate.
- There's also Susan becoming an Action Girl. In the book her adult self is described as not liking fighting "like an ordinary grown up lady", which is why she was named Queen Susan the Gentle. On the other hand both Anna Popplewell and Andrew Adamson said "if she was going to Stay in the Kitchen she should have been given a slab of bread and some butter, and not a bow and arrow."
- Die for Our Ship: The Susan/Caspian shippers, despite the fact that there's absolutely no mention of it in the books, they never see each other again, and Caspian marries Ramandu's daughter at the end of Voyage of the Dawn Treader. Curse you Andrew Adamson for including that kiss.
- Ensemble Dark Horse:
- The geek at the train station (Warren) gained a fan club when some fans decided they didn't like the way Susan's and Caspian's relationship was treated and that "Phyllis" was a much better pairing.
- Asterius the minotaur (the one who held up the portcullis, which is the only reason anyone aside from griffon-riding Edmund escaped with their lives) is held in high regard as well.
- Harsher in Hindsight: The use of "The Call" at the end of Prince Caspian will likely become this if a film adaptation of The Last Battle is made.
- Hilarious in Hindsight: On the one hand, you have Ben Barnes, whose portrayal of Prince Caspian drew upon Inigo Montoya; and on the other you have Eddie Izzard, who based his sword-fighting mouse Reepicheep on Errol Flynn, who also famously inspired Cary Elwes' performance. So their first meeting is really a The Princess Bride reunion by way of Captain Ersatzes.
- Love to Hate: Sergio Castellitto's take on King Miraz, making him a very effective and ruthless villain - with the occasional Pet the Dog moment to humanise him. Likewise he also gets some good Deadpan Snarker moments.
- One-Scene Wonder: Tilda Swinton returns as Jadis for one scene, as an expansion of a point in the book where they consider resurrecting her.
- Rescued from the Scrappy Heap: Those who don't hate the changes feel the film did this for the Prince Caspian story.
- Retroactive Recognition: Tyrion Lannister is slightly grumpier, but quite recognizable.
- Sophomore Slump: Sort of. This was the second book published (though the fourth chronologically), and it's commonly regarded as the weakest. The film is a mixed bag. Some felt it was a step down, others loved it.
- Strangled by the Red String: The romance between Susan and Caspian is accused of this. There was none in the book and it was Doomed by Canon anyway. The whole thing is very chaste and never progresses beyond simple flirtation—culminating in a small kiss at the end. Word of God is that the romance was more detailed in the original script, but cut down to a more chaste thing because they wanted to avoid it taking over the movie.
- They Changed It, Now It Sucks!: This film provoked this more than the first. Due to the book's iffy pacingnote , a lot of things had to be changed. Things that were especially disliked were the castle raid and the romance between Susan and Caspian.
- They Wasted a Perfectly Good Plot: It seems like the movie is building up to something interesting with Miraz's wife being shocked to learn of his evil actions, but then she's largely forgotten about. It's likely done to put some shades of grey in the Telmarines (such as Glozelle's Adaptational Heroism) and it does get a minor payoff when Prunaprismia is the first of them to volunteer to pass through into the new world.
- Unintentionally Sympathetic: Peter and Caspian's fight is meant to show that both of them have messed up majorly. Except Caspian abandoned his post in the middle of a covert military operation just to get some revenge - which he didn't act upon. The castle raid failing was far more Caspian's fault than Peter's - who was more trying to salvage the mess that Caspian made.
- What an Idiot!: The assault on the castle in Prince Caspian (which did not happen in the book) gave huge helpings of this to Peter. To be fair, everyone from Caspian to Lucy calls him out on it. Caspian also deserves a share of this one because it was his fault in the first place that they lost the element of surprise; he went into the castle with his own agenda and despite the obvious results of him changing the plan in the middle of a Stealth-Based Mission he shows no responsibility or remorse for his actions. To maintain order among the Narnian army, Peter has no choice but to let it go and share the blame.
- What Do You Mean, It's for Kids?: Prince Caspian was allegedly a children's movie and rated as PG. But despite that, Prince Caspian is probably the highest-bodycount, generally-dark movie to be given a PG rating since Indiana Jones and the Temple of Doom spurred the creation of PG-13. In addition, the villains here are not just some fantastical creatures, but men and women who Would Hurt a Child.
YMMV / Prince Caspian
