I’ve seen a little around the web about how Disney has pulled out of the deal with Walden Media to produce the Voyage of the Dawn Treader:
Officially Disney is simply failing to take up its option to partner on the planned third film in the series, The Voyage of the Dawn Treader, although it is rare for a studio to pull out of a franchise before it has been completed. It may be, however, that the fantasy bubble has burst, following the huge success of the Lord of the Rings and Harry Potter series: last year’s big budget adaptation of Phillip Pullman’s Northern Lights, The Golden Compass, tanked in the US with a haul of just $70m (£47m) – although it did better in the rest of the world, taking more than $300m (£200m). Nevertheless, Warner Bros and New Line made the decision not to film the rest of the series, despite the presence of Nicole Kidman and Daniel Craig on its cast list.
Narnia’s problems may have been inspired by the fact that the first film is based on a book which is far better known than any of its successors, unlike JK Rowling’s tales which have all proved equally popular.
