James Cameron's plans for his Avatar trilogy have been largely locked inside the director's head. We know that he intends to shoot two sequels back-to-back, but beyond that, there's little information to go on.
But in a recent interview with MTV, Cameron has revealed a little more on the Pandora-set sequels, including his thoughts on a fourth movie, which could well be a prequel.
“I have an idea for a fourth. I haven't really put pen to paper on it, but basically it goes back to the early expeditions of Pandora, and kind of what went wrong with the humans and the Na'vi and what that was like to be an explorer and living in that world."
"Because when we drop in, even in the first film, in Avatar 1 as it will be known in the future, we're dropping into a process that's 35 years into a whole colonisation.
Given that the next two movies will tie up the trilogy, it seems like a logical way to continue making Avatar movies, ala The Hobbit or, ahem, Star Wars.
"We'll start, not imitating Star Wars, but it's a logical thing to do because we'll have completed the thematic arc by the end of three. The only thing left to do is go back to see what it was like on those first expeditions and create some new characters that then become legacy characters in later films. It's a plan."
"You know, Peter Jackson had it easy, he already had the books."
The technology Cameron used to make Avatar made for a fiddly process, something he's hoping to improve this time around.
"We've spent two years refining the whole pipeline. It was a hideously complex process to make that film and a lot has been said about that, but we don't want it to be done in the same prototypical way as the first one, we want it to be a much smoother workflow just for creativity reasons."
Avatar 2 is likely to land late 2014, with the sequel appearing a year later.
