James Cameron shooting THREE Avatar sequels?

We already knew that James Cameron was planning on filming two follow-up films to his record-breaking blockbuster 'Avatar', but now Sigourney Weaver has suggested that there is also a fourth installment on the way.

Speaking to Showbiz 411, Sigourney Weaver has said that she will begin filming 'Avatar' 2, 3 AND 4 later this year.

Weaver says she doesn't know how long it will take to shoot the movies, or how it will all work. “I just show up” she said.

This is the first anyone has heard about a potential fourth film in the 'Avatar' series, so it still remains unconfirmed at this stage.

Cameron, however, has stated that the only films he is interested in making ‘Avatar’ flicks at the moment. One of the sequels will explore the underwater depths of the planet Pandora.

The director recently completed a successful descent to claim the world-record for the deepest ocean dive, so he's certainly done his research.
