The Chronicles of Narnia is a series of seven high fantasy novels by author C. S. Lewis. It is considered a classic of children's literature and is the author's best-known work, having sold over 100 million copies in 47 languages. Written by Lewis between 1949 and 1954, illustrated by Pauline Baynes and originally published in London between October 1950 and September 1956, The Chronicles of Narnia has been adapted several times, complete or in part, for radio, television, the stage, and film.

Set in the fictional realm of Narnia, a fantasy world of magic, mythical beasts, and talking animals, the series narrates the adventures of various children who play central roles in the unfolding history of that world. Except in The Horse and His Boy, the protagonists are all children from the real world, magically transported to Narnia, where they are called upon by the lion Aslan to protect Narnia from evil and restore the throne to its rightful line. The books span the entire history of Narnia, from its creation in The Magician's Nephew to its eventual destruction in The Last Battle.

The Chronicles of Narnia is a series of fantasy films from Walden Media based on The Chronicles of Narnia, a series of novels written by C. S. Lewis. From the seven novels, there have been three film adaptations so far—The Lion, the Witch and the Wardrobe (2005), Prince Caspian (2008) and The Voyage of the Dawn Treader (2010) which have grossed over $1.5 billion worldwide among them.

The series revolves around the adventures of children in the world of Narnia, guided by Aslan, a wise and powerful lion that can speak and is the true king of Narnia. The children heavily featured in the films are the Pevensie siblings, and a prominent antagonist is the White Witch (also known as Jadis).

The first two films were directed by Andrew Adamson and the third film was directed by Michael Apted. The third film is the first of the Chronicles to be released in RealD 3D. The fourth film is now being developed by Mark Gordon Company.

Development

C. S. Lewis never sold the film rights to the Narnia series during his lifetime, as he was sceptical that any cinematic adaptation could render the more fantastical elements and characters of the story realistically. Only after seeing a demo reel of CGI animals did Douglas Gresham (Lewis's stepson and literary executor, and film co-producer) give approval for a film adaptation.
