Acclaimed Hollywood filmmaker James Cameron is currently writing an Avatar Bible on which he will base the script for the sequel to his blockbuster 3D sci-fi epic adventure movie.
Sam Worthington who played the lead Jake Sully in the first movie has confirmed work has begun on the Avatar follow-up, with director Cameron writing a book on which to base the script, reports femalefirst.co.uk.
"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," said Worthington.
"Things like going underwater, going into the floating mountains," he added.
