The all-new 3-minute, 30 second trailer for James Cameron's upcoming science-fiction/action epic Avatar that played in front of Saw VI last weekend is now online. The clip delves deeper into the film's plot and features far more dialogue and action than the previous teaser trailer.

A four-minute making-of featurette has also hit the net, detailing the extensive digital innovations Cameron has helped pioneer for the movie.

Finally, the film's official website has gone up at www.avatarmovie.com.

Avatar marks James Cameron's first dramatic feature film since he completed Titanic 12 years ago, which remains the all-time unadjusted domestic box office champion with a $600.7 million US take (just under $940 million when adjusted for inflation). The film opens on conventional screens, 3D screens and IMAX 3D screens on December 18th.
