The Chronicles of Narnia (film series)
Development
C. S. Lewis did not sell the film rights to the Narnia series during his lifetime, as he was skeptical 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 eventual literary executor, give approval for a film adaptation.
Development
Although the plan was originally to produce the films in the same order as the books were published, it was reported that The Magician's Nephew, which recounts the creation of Narnia, would be the fourth feature film in the series, instead of The Silver Chair. It was rumored that The Magician's Nephew was chosen in an attempt to reboot the series, after The Voyage of the Dawn Treader grossed less than the two previous films. In March 2011, Walden Media confirmed that they intended The Magician's Nephew to be next in the series, but said that it was not yet in development.
Development
In October 2011, Gresham stated that Walden Media's contract with the C. S. Lewis estate had expired and suggested that Walden Media's lapse in renegotiating their contract with the C. S. Lewis estate was due to conflicts between the companies about the direction of future films. On 1 October 2013, the C. S. Lewis Company announced a partnership with The Mark Gordon Company and announced that The Chronicles of Narnia: The Silver Chair was officially in pre-production.
