While you're waiting for Prince Caspian to come out, you might want to check out the BBC's production of The Chronicles of Narnia.
Starting with The Lion, the Witch, and the Wardrobe, this three disc series faitfully brings to life C.S. Lewis' classics. While these productions don't have the special effects of the Disney film, they have their own really special charm, with great acting and fabulous costumes and sets. If you're a big Narnia fan, you don't want to miss these.
