To further that, I would have to note that Cameron really wants to add the oceans of Pandora to the mythos of Avatar. The place where he's heading,the Mariana's Trench is a site of sesmic activity. According to the Survival Guide, Pandora is supposedly sesmically active, and Hell's Gate has been built to withstand earthquakes. As someone who lives in a sesmically active part of the world, it interests me on how they will protray it. Hopefully not the stupid eath cracking open with landmasses falling into the oceans kind of spectacle like in 2012.

Well, now I can't wait to see Avatar 2 when it comes out.
