I heard about this and just found this story.

"The official Facebook page for The Chronicles of Narnia: The Voyage of the Dawn Treader has been updated with the first Production Blog on the film, scheduled to hit theaters on December 10. Directed by Michael Apted, the third installment stars Georgie Henley, Skandar Keynes, Ben Barnes, Will Poulter, Gary Sweet, Bruce Spence, Arthur Angel, Shane Rangi and Liam Neeson."
