It looks like we are going to returning to Narnia
The Silver Chair is set decades after “Voyage of the Dawn Treader” and sees “Eustace Scrubb and his friend Jill Pole are brought to Narnia by Aslan to find the missing heir of a now elderly King Caspian. The missing Prince Rilian disappeared while on a quest to find the green serpent that killed his mother. Eustace and Jill set off to the giant lands north of Narnia to find him, and encounter the Lady of the Green Kirtle and a young man who must be bound nightly to a magical Silver Chair.”
With the film acting as a reboot, the roles played by Ben Barnes (Caspian), Will Poulter (Eustace), and Liam Neeson (who voiced Aslan) will be recast but no information on any casting has yet been announced. Screenwriter David Magee (Life of Pi) will be writing the screenplay for the film.
The series began in 2005 with The Lion, The Witch and The Wardrobe and grossed over $745million; it’s sequel, Prince Caspian, earned $419million on its release in 2008; while the third film, Voyage of the Dawn Treader earned $410million. Walden Media, who distributed and financed the films thus far, saw their rights expire in 2011 before Mark Gordon stepped in.
