Coming from the Official Swiss Dawn Treader page on Facebook is the first behind the scenes video for The Chronicles of Narnia: The Voyage of the Dawn Treader. The video is in English, and features comments from Georgie Henley (Lucy Pevensie), Ben Barnes (King Caspian), producer Mark Johnson, director Michael Apted, producer Andrew Adamson (who you’ll recognize as the director of The Lion, the Witch and the Wardrobe and Prince Caspian), and Will Poulter (Eustace).
Big thanks to Daniel J for the referral. He’s also posted screenshots for your viewing pleasure.
