Wow. Such a difference between this site and NarniaWeb! Most people are having heart attacks over there. (And I say that with affection.)
They do kind of have a point. Until Walden gets a new distributor, VoDT simply isn't going to be made. One might hope that Fox would pick it up due to their close association with Walden, or some other company, but there's no guarantee of that.
I actually kind of preferred PC the movie to LWW the movie (though I like LWW the book better than PC the book). LWW the movie was more accurate to the "facts" of the story, but I have never seen an Aslan that was less of a Christ type. Andrew Adamson (the director) flatly said that Aslan is not Christ (as opposed to just leaving it open to viewers' interpretations).
And the script contained such cringe-worthy moments as Mr. Beaver calling Aslan the "top geezer" (!!), and all references to him being "the son of the Emperor Over the Sea" have been removed. Also, Aslan shows how "much" he knows about Peter by mentioning what Peter said earlier to Mr. Beaver (which Mr. Beaver clearly told him). In other words, this Aslan has no idea who the children are, or why they were called. That's a far cry from the Aslan who, in
The Silver Chair, would tell Jill, "My child, you could have not called me unless I was calling you first."
Meanwhile, while PC the movie wreaks havoc with the story and continuity (and I didn't care for this version of Reepicheep), one theme of the story came through loud and clear: Everything is a mess when the characters don't believe in Aslan or trust in him for help; everything turns around when they do. I won't attempt to defend PC as a whole, but in this regard at least, PC was superior to LWW the movie.
Whew. All of this to say, I'm not entirely broken up about the possibility of no more Narnia movies, because I haven't felt that Hollywood has gotten them right so far. On the other hand, I would like to see the series completed on film at some point. And a world where adorable little Georgie Henley doesn't get to keep playing Lucy would be a sad one by far.
