For fans of the burgeoning Avatar franchise, this sneak peek was a long time coming. The first two sequels were originally announced in 2010 -- and at one point Avatar 2 seemed slated for a 2020 release. But over the past almost decade, more films have been announced -- and the Disney/Fox merger also led to a delay. And James Cameron has also been waiting for technology he feels is good enough to properly capture all the underwater action of Avatar 2. In other words, it’s been a long journey to get to the point where we even see behind-the-scenes pictures. And hopefully we’ll get a few more sneak peeks before Avatar 2 (probably) hits theaters in December of 2021.
