After years and years of waiting and hearing all about the groundbreaking technology that Cameron has been using, we finally get to see what the world on Pandora looks like, and it's as awe-inspiring and amazing as I'd imagined. 20th Century Fox is bringing James Cameron's Avatar to both IMAX and regular theaters in 3D around the world on December 18th.
