Actor Sam Worthington told Moviefone.com about a a sequel of ‘Avatar 2′

“We’ve been discussing that with Jim. He had some ideas he told us while we were filming, which were really cool and out there,” Worthington said during Moviefone’s visit to the set of his new movie, ‘Man on a Ledge.’ “At the moment, he’s still writing what he calls ‘The Bible’ and detailing the world. Once he’s detailed the world – more so than it’s already detailed in his big brain, anyway — then he said he can write the script and we can go explore the world – things like going underwater … going in the floating mountains.”

“I always joked and said that they were married and Jake Sully got lazy and Netiri kicked his butt,” he said.

“But there is something to [the notion of being] in a genetically-engineered body now, which he is. Is there a “use by” date on it? I don’t know. What’s the new dilemma? Is it just humans coming back, or is something even bigger than can threaten them, can threaten the world? We can look at our world again and see that we know we’re hurting the environment, and we know we can do things about it. But what else are we doing that’s wrong so it can reflect on our own life?”
