One of the big selling points for Avatar is the film’s state-of-the-art motion-capture CGI for the “Na’vi” aliens. I do say that the creatures look quite realistic — for blue cat-like beings that is.
As briefly seen in this trailer, the title comes by how the protagonist (played by Sam Worthington) mentally inhabits a Na’vi clone (or avatar). After that story set-up the rest of the trailer is just made up of action shots, which demonstrates how well done the CGI is (since about 90% of the action involves the Na’vi’s).
While I’m still disapointed I won’t get to see the extended preview tomorrow, this definitely looks to be a film I should not miss when it is released in December.
