James Cameron has revealed that Avatar is the first movie in a trilogy.
Avatar has been in production since 1994 but Cameron appears to be confident that any future movies would not take as long to make.
Speaking to MTV the director said: "I have a trilogy-scaled arc of story right now, but I haven't really put any serious work into writing a script.
"From the time we capture and finish the capture, it's literally nine to 10 months to get the CG characters working, to get their facial musculature working.
"So now we have Jake, we have Neytiri. Sam can step right back into it, the characters will fit them like a glove, and we'll just go on.
"So a lot of the start-up torque that had to be done for one movie really makes more sense if you play it out across several films."
According to MTV we could be seeing the sequel hit cinema screens as early "as soon as 2012, 2013."
The film has grossed $285 million in it's opening weekend at the global box office capturing the #1 spot in both America and the UK.
Avatar is out now.
