It has been announced that The Chronicles of Narnia: The Silver Chair is in the works for a movie adaptation.
The Mark Gordon Company has agreed with the CS Lewis Company to work on a fourth movie in the series based on Lewis’s fantasy series.
Gordon said "Like many readers, both young and old, I am a huge fan of CS Lewis's beautiful and allegorical world of Narnia. These fantasy stories inspire real-world passion among millions of devoted fans around the world. As we prepare to bring the next book to life, we are humbled and excited to contribute to the outstanding legacy of Narnia."
Lewis's stepson Douglas Gresham said: "I have a great deal of respect for Mark Gordon's work and am confident that together we can bring the beauty and magical delight that Narnia engenders in the hearts of those who read the books to the screen in The Silver Chair. I am very much looking forward to diving once more into Narnia, this time with Mark Gordon and his team."
