It has been confirmed that James Cameron could shoot three more Avatar eventually. A fourth film, which is not actively being worked on and would probably follow his long awaited Battle Angel Alita adaptation, would be a prequel.
“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,” said Cameron. “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 in to a whole colonization.
“We’ll focus on Avatar for the next four or five years. Hopefully right after that . . . I am confident you will see [a Battle Angel movie].” said Avatar producer Jon Landau. “It’s one of my favorite stories, I think it is an incredible story, a journey of self-discovery of a young woman. It is a movie that begs the question: ‘What does it mean to be human Are you human if you have a heart, are you human if you have a mind, are you human if you have a soul ‘ And I look forward to bringing that film to audiences.”
