"We're still in the early stages. Right now we're developing the software. I'm writing the scripts. We're designing all the creatures and characters and the settings, and so on. So, I'm not actually directing yet, but I'm doing all the other creative processes that lead up to that," Cameron said.
He added that he thinks "it's going very well. I think it's going to be spectacular. You'll see new worlds, new habitats, new cultures. The primary conflict between the human view kind of dominating nature and the Na'vi view of being integrated into nature is the same, but it manifests itself in very different ways."
As far as the tech behind the upcoming films, they have greatly reduced how long one movie will take to make. "The first film… took almost four years to make. We expect to be able to accelerate the process quite a bit, because we've improved a lot of the software and the computer graphics tools, and we've been working very closely with Weta Digital down here in New Zealand developing a whole new suite of tools to speed up the process."
Cameron also said they are "looking at high frame rate. I'm studying that. I haven't made a final decision yet, whether the entire film will be made at high frame rate or parts of it. You know, we'll be shooting at a native resolution of probably 4K and so then there should be a lot of true 4K theaters by then as well."
So what can we expect story wise? "The thing that's great about 'Avatar,' it's such a rich world, I can explore any theme or any idea that I want. Once you've got the characters that an audience loves, it's great to surprise them and make changes and turns that they don't expect. And you don't have to spend so much time of the movie setting up all that stuff, because the audience will remember from the previous film."
