James Cameron says he wanted to give the fans more than a 3-minute trailer to give them an idea of what to expect from his first non-documentary feature film in 12 years, the very-eagerly anticipated (by fanboys everywhere) “Avatar.” So on Friday he allowed audiences to get an almost-20 minute preview, IMAX screen, 3D glasses and all. And I was there.

It was not exactly what I expected, more of a fantasy CGI film than live action with special effects. At first it felt more like a top-quality game without a controller than a movie. But then I was drawn into the story, thanks in part to the detail of the graphics but more because of the voice talent — Sam Worthington, Sigourney Weaver, Zoe Saldana. The movie opens in December and I am very much looking forward to it.

Here is the teaser trailer:
