Director James Cameron Previews Scenes from "Avatar," Starring Zoë Saldana

Ok, we are officially counting down the days until James Cameron’s Avatar is released in theaters on December 18th. The director debuted clips from his highly anticipated new 3-D film at the Cinema Expo in Amsterdam. The whole thing was very top secret and media wasn’t allowed to report on the screening, but people at the event posted anonymously online that the footage was "jaw-dropping" and "stunning.”

The film, which features Zoë Saldana and Michelle Rodriguez, is expected to take moviemaking to new heights. "Three years ago, I stood up here and said the 3-D renaissance is coming,” Cameron said at the screening event, “and from what we've seen in the business, we can now say it has arrived." In introducing the footage, Cameron said much of it came from the first third of the film but that there were also glimpses from unfinished portions of later battle scenes involving warring sides clashing over control of the fantasy world Pandora. The crowd reportedly gave the footage a standing ovation in the end.

One Twitter user, who was also at the event, wrote, "This will change movies forever," while another said: "Footage from Avatar was stunning, literally jaw-dropping. Amazing visuals unlike any before seen, with incredible detail."

Saldana was also on hand to talk about her character in Avatar, which was filmed using a mix of CGI, motion-capture animation and live action.
