from Galin

if Jackson was so concerned with accuracy he could have easily achieved it by incorporating only the Elvish from the books. Ok he didn't, so, so much for 'accuracy' step one.

What Peter Jackson was concerned with was making the best possible film he could make and having that film be a success by the standard measurements common in the commercial film business. And by those measurements it was a wild success.

Accuracy ---- what the heck is that? No film adaption is anything near the realm of "accuracy". Its an entirely different medium. One cannot adapt anything accurately from a book into the far different medium of film unless you use the book as your shooting script . Anything else is change. Accuracy regarding something as an obscure language which hardly anyone speaks is irrelevant as far as a films success is concerned. It would mean nothing either way and as such is a non issue.
