We know that James Cameron is planning at least three Avatar sequels, and Sam Worthington, Zoe Sladana, and Stephen Lang are officially signed on to reprise their roles. But according to FOX CEO Rupert Murdoch, there could be more.
In a recent interview with Fortune, he said that Fox is planning to “step up our production of major films” and has “one or two or maybe more sequels to Avatar.” The first Avatar film is set to be released in 2016, and when talking about the release date, he said,
“If we make it, it will be the first time [director] Jim Cameron’s been on time or on budget. But he’s never lost me. When he finally comes through, they’re just huge hits.”
Again, we know that Cameron is planning on making three more Avatar movies and that he will shoot them back to back. If they all do well at the box office and make billions of dollars like the studio is hoping, then I'm sure the studio will want to keep making them, and they'll give Cameron whatever he wants to do it. Of course, Cameron could always say no and a new director could take over.
