The moment that has to work in any Narnia movie is the moment where the kids move from one world to the other.

After all, that's the thing that hooks you in the first place when you read the story for the first time.  If you start with The Lion, The Witch and the Wardrobe, the first time someone walks towards the back of the wardrobe and finds, instead of the back panel, a winter forest.  It's a magic image, primal and evocative.  It's an inviting fantasy moment, and one of the masterstrokes of the entire career of C.S. Lewis.

With this new trip back to Narnia, Michael Apted steps in as director.  The franchise has shifted studios, too, with Walden now releasing the film through Fox.  I keep forgetting there's actually a new Narnia movie out this Christmas, and that it stars my two favorite kids from the previous movies, now getting older and taking center stage.

In this clip, Lucy (Georgie Henley) and Edmund (Skandar Keynes) are about to make their return to the magical land where they are royalty, and the clip gives you a sense of how Apted's style is going to adapt to the already-established look and feel of this particular franchise.

It's interesting how very different this franchise is than either "Lord Of The Rings" or "Harry Potter" in terms of how it's been handled.  There's odd consistency from film to film, both in front of the camera and behind it, and based on what I've heard about this one, it seems like they're getting looser in terms of adaptation.

We'll see what they've done with "The Chronicles Of Narnia: The Voyage of The Dawn Treader" when it hits theaters on December 10, 2010.
