As I said in a previous thread, and I will say this again;
Lord of The Rings, and any J.R.R Tolkien IP; is essentially Pandora's Box for the theme parks. You will deal with a world of pain, for whichever path they may take in how they adapt the works of J.R.R Tolkien's fantastical world. And yes, the films will be used; if they go in that path, but how they implement the films to a theme park setting will be the ultimate challenge.
