Out talking up the Blu-ray release of "Titanic 3D," James Cameron talked to Hero Complex about the challenges of writing the scripts for the back-to-back "Avatar" sequels. In the process he gave a comparison to another high-profile sequel, and what he hopes to avoid:
"It's a little bit of a daunting writing task because it's two scripts and they've both gotta be done at the same time. I'm writing it as separate stories that have an overall arc inclusive of the first film. I don't want to suffer from the 'Matrix 2' problem, where it just ends, like, what the hell? It's gotta end. There's gotta be a sense of conclusion, but also a sense that the journey will continue, and that's a fine line."
He re-affirmed that the oceans of Pandora are the playground for much of the second film:
"We're making up an ocean ecosystem for Pandora. That's gonna have less to do with the deep exploration that I've done than it has to do with my concerns about conservation of Earth's oceans. These are the things that concern me… [The film]won't take place completely in or under the water. That's just part of the environment of Pandora that we're going to see."
