Dawn-Treading Where They Shouldn't?

Let's just be clear. These Narnia movies aren't supposed to be based on the books. They're supposed to be based on the filmmakers' memories of the books, which they might not have read since childhood. Because, you know, those memories will be so much better than the books. And who could expect a busy filmmaker to actually read the novel he's adapting?

The best I can hope, I guess, is that they come up with a compelling script, as Cuaron did when he "adapted" Children of Men while disregarding the source material. But the first two efforts haven't made me optimistic...

Here's the update, via a link that Glenn McCarty sent in:

He added that "Adamson said something that was so smart early on. I had just re-read the book and he said, I don't want to make a film based on 'The Lion, The Witch and The Wardrobe,' I want to make a movie based on my recollection of it. He took a 9-year-old boy's imagination. He saw things that are not even in the book. Lewis left, sometimes major battles, on a single page, so Adamson just re-imagined it."
