Any additions or structural changes to the story support the themes of the book nicely, including making one famous sequence with Aslan, rendered here potentially in a dream. Says Adamson: “There is a problem there that you can get away with in the book because the story is told in retrospect … Aslan is there and he doesn’t do anything. But we had a problem with that cinematically because once you show Aslan, if you don’t have him do something people are going to ask ‘Why is all this happening? Why doesn’t he do something.’ It became really hard to see how this magnificent creature came along and hung out with the kids, and not do anything to stop all this carnage.”

At its core, Prince Caspian is about belief verses doubt, a theme familiar to those who know the work of C.S. Lewis. The Telmarines don’t believe in Aslan and the old Narnians. Lucy sees Aslan but her siblings don’t believe her at first.

“You believe, then you see,” says Will Moseley about Narnia. “The analogy is there that Aslan represents God. People say every day ‘if God is there why can’t I see him.’ Peter, Susan and Edmund say the same thing, ‘why didn’t I see him, he is an unbelievably huge lion why can’t I see him?’ Because they don’t believe. When Peter feels remorse about his sins, then the magic starts to happen. Almost like you open yourself up to believe, then you can see. I don’t think it has anything to do with aging … it's more to do with your strength in belief.”
