The following review is for the original theatrical release of Avatar from December 2009 and NOT the special edition that's being released in theaters in August 2010. Our policy is not to re-review movies when they're re-released in theaters (or on DVD) as special editions, director's cuts, unrated versions and such. The reason is that such new versions are not made available from the studios for review, nor is just the newly added and/or edited material. All of which means we'd have to complexly re-review the film from scratch - usually around a 10 hour process - for a new version that's just a few minutes longer than the original work.
Regarding that new material, here's what we found in a story in The New York Post :
"We do see a little bit more between Jake and Neytiri on their night of romance, though it's absolutely nothing that changes the rating," Cameron said. "To be honest, there wasn't much more to show -- we're pretty much putting in every frame, and it's only an additional 20 seconds."
The other eight minutes and 40 seconds opens a Pandora's box of other moments:
More shots of a schoolhouse run by Sigourney Weaver's Dr. Grace Augustine. "That's a very interesting set piece, about two minutes long, a rich scene with big action-adventure stuff and a hunt featuring these herd animals called Sturmbeests," Cameron said.
Extra footage of the death of Na'vi clansman Tsu'tey, Jake's romantic rival. "You see him after the battle," Cameron said. "Jake and Neytiri come to him, and it's this incredibly powerful scene. In fact, I was practically booed out of the room when I told everybody I was going to take it out of the movie in the first place."
A scene Cameron calls "the drums of war," which he hopes will clarify why the humans choose to wipe out the Na'vi. He compared it to America's decision to invade Iraq. "We had to provoke Saddam to do something stupid, and it's like that with the humans invading Pandora," he said. "I felt when I was writing it that the Na'vi had to counter-react and do something that is called an atrocity that gave [humans] the moral right to go in and destroy and displace them. The additional footage is pretty short, but it fulfills that purpose."
