In the three Lord Of The Rings films there will be around 65 speaking parts, and while prosthetics and other special effects will be used, the only fully computerised character will be Gollum.
“He’s the little emaciated guy who’s been kind of poisoned by the ring over 500 years,” Jackson explained. “He is actually a key character in the second and third films, but he doesn’t do much in the first. There are all sort of creatures and monsters that will be created on the computer but Gollum’s different because he says dialogue and has to have an emotional connection in the story. He’s very much a real character.”
