Cameos
Differences between the book and film
- In the film, Edmund attempts to enlist in the army, only to be thwarted by Lucy, similar to how she embarassed Susan in the previous film.
- In the film, Eustace makes up a limerick, not a couplet.
- In the film, Eustace addresses his parents as "mother" and "father" whilst in the book, he addresses them by their names, "Alberta" and "Harold".
- In the book, Reepicheep challenges Eustace to a duel before arriving at the Lone Islands; this challenge is replaced with a duel between Caspian and Edmund in the film and Reepicheep and Eustace later have their own duel after visiting Narrowhaven.
- At the Lone Islands, Caspian instructed his men to keep silent about their identities, and only revealed who he was to Lord Bern after he bought his freedom, having been reminded of Caspian's father. In the movie, Caspian shouts "I am your king!" the second they are ambushed by Slave Traders, and meets Lord Bern in the cell where the Slave Traders throw him and Edmund.
- In the book, Caspian learns from Lord Bern that the Slave Traders have been allowed to operate without interference from the Governor, Gumpas, who sees the practice as unavoidable and necessary for the economy. In the film, Caspian learns from Bern that the Slave Traders have been making sacrifices to a green mist.
- In the film, Lord Bern had not left Narrowhaven because he had been captured and imprisoned by the Slave Traders. In the book, he had not left because he had married and settled down there.
- In the film, Rhince is a Narrowhaven citizen who joins the voyage to find his wife, who is sacrificed to the mist. In the book, Rhince is a high member of the Dawn Treader crew.
- The Dark Island takes the form of a green mist, becoming a sort of sentient threat seeking to "corrupt all goodness" and "steal the light" from the world, rather than the embodiment of fear in Narnia.
- Caspian is much older and wiser in his personality and manner in the film than in the book, most likely because of the differences in his age. In the book, he is coming of age, close to Edmund and Lucy's ages, whilst in the film, he is in his early twenties.
- In the book, Eustace tries to steal water whereas in the film, he tries to steal an orange.
- The geography has been drastically changed for the film, resulting in some of the islands being visited in a different order than they were in the book. In the book, Dark Island came before Ramandu's Island; Dragon Island and Goldwater Island were two separate islands, neither were volcanic and both were visited before Coriakin's Island.
- In the film, Reepicheep never accompanies Caspian, Edmund and Lucy as they explore each of the islands.
- In the book, the ship is caught up in a violent storm for two weeks after departing Narrowhaven and arrives at Dragon's Island badly damaged. In the film, the storm comes after departing Magician's Island and before arriving at Goldwater Island and no serious damage is caused.
- In the book, though it's assumed that Lord Octesian died at Dragon's Island, it's implied variously that he was either killed by or transformed into the dragon that Eustace encounters. In the film, Lord Octesian's remains are found among the dragon treasure and identified by Caspian, though like in the book, it is uncertain what actually killed him.
- In the film, Edmund is tempted by the powers of the gold water pool on Goldwater Island. In the book, it was Caspian who was tempted.
- In the film, Coriakin turned the Dufflepuds invisible to protect them from the Green Mist, and they seek Lucy's help because they can't read. In the book, the Dufflepuds turned themselves invisible after Coriakin turned them "ugly" and they sought Lucy's help because only a girl could reverse the spell, but they were too afraid to send their own daughters.
- Eustace remains a dragon much longer in the film than in the book. In the book, he was unable to follow the Dawn Treader at sea, whilst In the film, he is able to pull the ship when there's no wind.
- In the film, a page from the Book of Incantations tempts Lucy by showing her as the exact image of Susan; she also casts a spell to make it snow indoors. In the book, she imagined her beauty surpassing Susan's and harmfully used a spell to spy on her friends.
- In the film, Ramandu's daughter is a star, not half-star and is named Lilliandil. Her father never appears in the film.
- In the book, Lilliandil's dress is blue whilst in the film, her dress is white, though the colour of her starly glow is blue as she is a blue star.
- Lilliandil says that the three Lords were put into a sleep because they were half-mad and threatening violence upon each other when they arrived on the island and "violence is not permitted at Aslan's Table", whereas in the book, they slept because one of them took the Stone Knife and they were not meant to touch it.
- In the book, Caspian flirts with Lilliandil by referencing Sleeping Beauty. In the film, he states in a formal manner that she is the most beautiful woman he has ever seen.
- In the book, the Sea Serpent was a dumb brute encountered before arriving at Goldwater Island. In the film, the battle with the Sea Serpent at Dark Island is the climax and the monster is a manifest of the green mist after Edmund accidentally conjures it when thinking of his fears.
- In the book, Caspian was forbidden by Aslan to sail to the World's End.
- In the film, Aslan nevers shows up at the World's End in the form of a lamb.
- In the film, Eustace and Jill Pole are already friends as Jill is mentioned to be visiting Eustace at the end of the film; they were not friends in the book and only knew each other by surname.
Production
Michael Apted was announced as director on April 17, 2007; Andrew Adamson, director of the series' first two films, and Mark Johnson are slated as co-producers. Apted grew up reading the Narnia novels. Bob Beltz of Walden Media said the production company deliberately set up a fast-paced, staggered shooting schedule for the Prince Caspian, The Voyage of the Dawn Treader, and The Silver Chair films "in a way that it won't have to be two and a half years between them. We'll be able to bring them out sequentially a year apart". Michael Apted described taking over direction of the series as easy, "What’s fascinating about this particular franchise is how different all the stories are... there’s no element of Narnia in it at all. This is a journey that Caspian the Tenth is making into the islands, outside to the east of Narnia. So it’s interesting, it’s a whole different tone to the other things".
Production designer Roger Ford was replaced by Jan Roelfs. The owners of an AUD 2.1 million 40 metre by 30 metre by 5 metre water tank at Warner Roadshow Studios in Queensland are negotiating with the production company, in the hope that The Voyage of the Dawn Treader will be filmed there. Filming began in May 2009.
Due to Prince Caspian.

In late November 2009, three stills from the film were released on the social networking site, Facebook.
