- Actor Allusion: In the BBC TV adaptation of The Lion, the Witch and the Wardrobe, Professor Kirke is played by Michael Aldridge, who essentially plays a softer version of his character Seymour Utterthwaite from Last of the Summer Wine, a former headmaster. This is particularly noticeable with his use of Kirke's Catchphrase:Kirke: What DO they teach them in schools these days?
- Channel Hop: The current film adaptation has jumped from Disney to 20th Century Fox to Sony and eOne. A rare example of a film series doing this, as only a few other film series such as Hellboy and Terminator have done it.
- The Danza: A minor one. Edmund's horse Phillip is voiced by Phillip Steuer.
- Development Hell: Due to rights issues, the fourth film in the series is "on hold indefinitely". The franchise isn't officially dead yet, but is certainly on life support. A director for the film was finally announced on April 2017.
- Dyeing for Your Art: A minor case. Georgie Henley's hair was actually lightened for the film (as Lucy is a blonde in the book) but it's not that noticeable.
- Enforced Method Acting:
- To create the right slightly creeped out vibe between the characters, Tilda Swinton (who played the White Witch) would spend time in between shots subtly hitting on Skandar Keynes. Who would have been around 14 at the time.
- The four principles were not shown the snowy Narnia soundstage until they were filmed first entering it from the wardrobe, so that their awestruck expressions would be genuine.
- In a bit of a meta case, the film was shot in as close to chronological order as possible (as opposed to a normal filming regimen, which is scheduled based on when sets are available and so on), so that the childrens' emotional growth onscreen would be reflected by their physical growth throughout the shoot.
- Extremely Lengthy Creation: C. S. Lewis first pictured the faun from The Lion, the Witch, and the Wardrobe when he was sixteen. He finished the book when he was fifty.
- Follow the Leader: The Narnia books had been adapted into live-action before, but the Narnia feature films came in the wake of the movie versions of Harry Potter and particularly The Lord of the Rings (the original being written by Lewis's fellow Inkling J. R. R. Tolkien). Just like (and probably because of) the latter, the battle scenes are considerably beefed up compared to the books.
- Franchise Killer: The Chronicles of Narnia: The Voyage of the Dawn Treader, while a box office success, received less than stellar reviews than Prince Caspian and The Lion, The Witch, & The Wardrobe, and the contract from Walden Media expired in April 2011, thus making it the third and final Narnian adventure.
- Keep Circulating the Tapes: Because the books, for most their entire published history, were ordered in publishing order and only recently re-ordered by a different publisher, older volumes of the series that maintain the classic numbering go for a lot more money today than they used to.
- Money, Dear Boy: Following the 2010 release of the film version of The Voyage of the Dawn Treader, 20th Century Fox planned to film The Magician's Nephew next instead of The Silver Chair, after noticing that the films have so far grossed back amounts that roughly correspond to the popularity of the book involved - and The Magician's Nephew is usually considered the second most-popular in the Narnia series. However, as of 2019, it hasn't been made and with Netflix taking the rights to the franchise, likely never will be made by Twentieth Century Fox.
- Network to the Rescue: After Disney was disappointed with Prince Caspian not performing quite as well as The Lion, the Witch, and the Wardrobe they decided to pass their option to release The Voyage of the Dawn Treader due to budget disputes, at which point 20th Century Fox promptly offered to pick up the contract. Some see this as a What an Idiot! move for Disney, as Prince Caspian is generally regarded as one of the least popular books in the series, while The Voyage of the Dawn Treader is the most.
- The Other Darrin: Now that a film adaptation of The Silver Chair has finally been announced, Eustace Scrubb will be recast since too much time passed between films and Will Poulter is now a grown man.
- Referenced by...: Kill Six Billion Demons. When heroine Allison returns to our world after an unwanted excursion to the parallel reality of Throne, one of her friends says "Because if you have been to Narnia, you better tell me."
- So My Kids Can Watch: Makeup effects artist Howard Berger, whose prior credits include Hostel and Sin City, mentioned in an interview that this would be the first movie he worked on that his kids could watch. He later won an Oscar for his work.
- What Could Have Been: Lewis originally had plans for an eighth book called Susan of Narnia, which would have been all about Susan after the events of 1949, and would have apparently been how the books themselves came to be, wherein Susan explained things to Lewis himself, and presumably ending with her joining the other Seven Friends of Narnia in Aslan's country. However, he died before he could write this. Since he died in 1963, and The Last Battle was written in 1956, this suggests the book was in Development Hell.
- The Wiki Rule: WikiNarnia.
- Edmund's actor, Skandar Keynes, is Charles Darwin's great-great-great-grandson.
- In Russian translations of the Narnia books, the land of Calormen is renamed as "Tarkhistan" (Тархистан), as a reference to the Tarkaan nobles and its Turkish and Persian cultural influences..
