‘Avatar' has already piled up USD 620 million in worldwide grosses and, of course, in our "what's next?" culture that means people are already peppering writer-director James Cameron with questions about a sequel. When asked about the follow-up possibilities for the film, Cameron hinted that it may indeed be a possibility.

When a journalist pointed out that Pandora wasn't the only moon shown orbiting the distant ‘Polyphemus', the filmmaker acknowledged that his story ideas for the ‘Avatar' universe aren't boxed in by Pandora.

"I have some story ideas in my mind, and I'll start working on them once we're settled with ‘Avatar'." Cameron replied.
