According to a source at Disney, who requested anonymity, Prince Caspian, the second story published in the Chronicles of Narnia, has been greenlit for a December 2007 theatrical release. Disney was hoping for a $60 million opening weekend for The Lion, the Witch, and the Wardrobe and since the film’s opening exceeded their expectation they are moving forward.
Don’t expect an official announcement until later in the week or possibly as late as January. Adamson hasn’t decided whether he will direct the new film, but most think he will be back. The script is very nearly finished, and the general feeling is that with a lot of the tech in place for the picture (e.g. Aslan) they could start the shoot on New Zealand’s South Island as early as this summer.
A big thanks to ‘Pogostick’ for the information. This hasn’t been officially confirmed by the studio.
Remember, Prince Caspian would be the next one filmed, because it’s the next one that features the four children from the Lion, the Witch and the Wardrobe.
