Empire recently spoke with Avatar producer Jon Landau, who revealed that the highly-anticipated sequel Avatar 2 will not take place completely underwater in the oceans of Pandora. Here's what the producer had to say:
"Water will be a part of the movie, but it won't be all of the movie. There's been a lot of rumors that it's an underwater movie - it's not. Just like the Floating Mountains, and the Na'vi's interaction with the mountains, were a part of Avatar, it'll be the same type of thing."
