I heard that the original plan for the Narnia movie was to remove all the "Christian elements" from it to make it more "mainstream", but that plan was scrapped. Hollywood believes in the worship of self and nothing else.
I may be wrong, so don't accept this w/o checking, but I seem to remember a quote by the director of "Narnia" that made him sound almost hostile to the Christian underpinnings to the story.
But from what I've heard (I haven't read the books), Narnia is like Lord of the Rings in that an adaptation that is at all faithful can't help but have Christian themes.
You mean the movie "The Pagan Matriarch, the Carnivore, and the Storage Unit for the Skins of Murdered Animals"?
