Avatar 2, 3 and 4 Will Be Shot Back-to-Back

Sigourney Weaver, who played Grace in Avatar, has told Showbiz411 that the second, third and fourth chapters of James Cameron's big, blue, 3D behemoth will be shot back to back starting September.

Despite dying in the first movie, Weaver says she's back on board. The actress didn't know the full schedule, claiming she'll just "show up".

But don't bother getting excited yet, the fruits of this profit-maximising move won't hit cinemas until the end of 2014. Cameron said last month that he may well spend the rest of his career dedicated to the Na'vi.
