"But Cameron fell hard for Sam Worthington and in the end, let’s be honest, it really didn’t matter who they cast. Avatar is all about spectacle. It’s the massive, epic scale of Pandora and all of Cameron’s whiz-bang 3D effects which have propelled it to the top of the box office. Mostly though, Cameron just loved Worthington’s accent. He says, “You hear Sam talk and he sounds like Crocodile Dundee — but you hear him in the character and he's utterly and completely the guy.” Start practicing your Croc Dundee impression Matt Damon and maybe you’ll get a part in Avatar 2".

"Even Cameron himself has thought about the prospects of further "Avatar" installments. In an interview with Hero Complex, the director revealed that future sequels could involve Pandora's neighboring moons and even the central planet, known as Polyphemus.
"The planet in Pandora's sky is called Polyphemus and it's the primary for a system of moons, just like in our solar system, Jupiter has fifty some moons and they're discovering smaller ones all of the time," said Cameron.Perhaps the fourth and sixth moons will be the subject of the next "Avatar" films. Do these moons contain new sources of unobtanium for Earth's population? Is there yet another indigenous race ready and waiting to protect their land from humanity?" Source: moviesblog.mtv.com
