On May 1st, there was a Biolamedia conference at the CBS studios in Hollywood, where they showed the trailer to The Chronicles of Narnia: The Voyage of Dawn Treader. As word has it, Anna was actually in the trailer as Susan Pevensie! This is surprising because Susan and Peter are not in the Voyage of Dawn Treader book by C.S. Lewis, and Anna has said she did not return to film VDT. However, speculations are that this could be a flashback scene, or similar to when Tilda Swinton was CGI’d in Prince Caspian, from footage they had of her from the previous film. We also know that Anna did visit the set of VDT, although she didn’t formallly announce participating in filming while she was there.
The scene has Susan appearing in a spell book that Lucy is looking at. When Lucy turns to the spell of ‘beauty beyond the lot of mortals’, an image of Susan conjures into her mind and onto the page. Here are some reports on the scene:
Aslans Country:
Lucy walks down the hall to the magician’s book. She opens it as Aslan’s voice speaks in the background. Snow falls as she gazes around in wonder. Another clip of the book includes Lucy looking on the page of the spell of beauty beyond the lot of mortals, and her image in the books morphs into an image of Susan.
The Lions Call:
On the Island of the Voices, we see Lucy approach Coriakin’s Book. At first, it bears a number of scrambled letters placed at random on the cover, but once unclasped, the cover reads “The Book of Incantations.”
At one point, standing before the book, Lucy apparently causes it to snow, covering the room in white and bringing a smile to her face, reminiscent of her first foray into Narnia. Later in the trailer, she looks into the book and sees a picture of herself that morphs into the face of her sister Susan.
Narniafans:
There was a good scene of Lucy in the Magic Room. Beautiful set. Aslan fast forwards Lucy through the book. Lucy says a spell and Susan appears in the window. Yes, Anna Popplewell makes an appearance.
I hope this means the trailer is coming to the public soon! We will keep you posted
