He also thinks expensive, and has a reputation for big budgets (Avatar's was rumored to be between 200 and 300 million dollars). The thing is, you can see where the money went when you watch one of Cameron's films. He's a film techie who specializes in creating new ways of making films, and Avatar promises to revolutionize (again) digital filmmaking. The movie lives up to its promise, with gorgeous CGI, excellent and smart use of 3-D technology and the best use of performance capture technology to date. It also might be the first antiwar, anti-imperialist, tree-hugging environmentalist cowboys-and-Indians space Western. I'm pretty sure that it is, in fact.
The year is 2154, and Earthlings have invaded a distant planet called Pandora: a world that has the misfortune of being a rich source of unobtainium, a valuable mineral. Even more unlucky are the Na'vi, a race of tall blue-skinned people who live in harmony with Nature and object to the strip-mining of their world. You know how humans are: What they can't take by force, they take by using more force. The Na'vi have bows and arrows; the humans have heavily armed mercenaries with machine guns, hovering gunships and mechas.
They've also got it in mind to use a little deception. They've created avatars: hybrid creatures grown from human and Na'vi DNA, who look enough like the Na'vi to pass for the real thing, almost (although the avatars have five fingers to the Na'vis' four; the film is brimming with such small details). A human controls his or her Na'vi avatar from a remote, wired pod, walking among the natives in a tall blue body.
Jake Sully (Sam Worthington) has a Na'vi avatar, but he's also an avatar of sorts in his own right: He's a replacement for his identical twin brother, now dead, who was meant to "pilot" the Na'vi body. Jake, unlike the other pilots, is an ex-soldier, and a paraplegic who finds his Na'vi body liberating. It allows him to walk and jump and run again, and also to do all the things that the lithe, catlike Na'vi do well. The avatars were created by Dr. Grace Augustine (Sigourney Weaver), a botanist who wants to learn about the Na'vi and the very unusual and interesting planet on which they live. Colonel Miles Quaritch (Stephen Lang), the chief of security for the mining company, has other ideas: He wants Jake to infiltrate the Na'vi, all the better to destroy them. Jake throws a wrench into the colonel's genocidal plans when he goes native.
Cameron developed a new performance capture technique to create the Na'vi. Performance capture (or motion capture) uses live actors wearing sensors that track their movements, which are then used to render them digitally as animated figures. Efforts to use the technology thus far have generally failed in two important ways: The animated people fall into the Uncanny Valley (whereby human facsimiles look almost real, but also slightly off - the sum total being altogether eerie and disquieting), and they have dead eyes and expressionless faces, which adds to the creepiness. (Peter Jackson has used the technology to best effect thus far in the creation of Gollum in Lord of the Rings.)
Avatar gets it right: no Uncanny Valley, and the faces of the Na'vi are expressive, dynamic and alive. The overall movements of the Na'vi bodies are pretty close to perfect (the avatars are clunkier, as might be expected), and also a great leap forward. And Pandora, the beautiful jungle world, is just gorgeous: Filled with bioluminescent plants and creatures, flying dragonlike beasts, little things that look like flying jellyfish and a few carnivorous nasties lurking about among the giant ferns and flowers, it's a glowing, shimmery, unspoiled paradise - a paradise that will be lost and despoiled if Quaritch has his way (and worth seeing in like-being-there 3-D, or Imax 3-D, if you can).
Cameron wrote and directed Avatar, and it is peopled by the usual types who populate his films: heartless, mercenary military and corporate guys, a couple of nerds (Joel Moore and Dileep Rao) and a tough woman - or in this case, three of them, with Weaver's Augustine, Michelle Rodriguez's fighter pilot Trudy and Zoe Saldana's Neytiri, the Na'vi woman who mentors Jake. The Na'vi are pretty clearly meant to call to mind the aboriginal peoples of Earth, who haven't done so well by colonialists. In some ways, Avatar is a straightforward (if otherworldly) cowboys-versus-Indians Western - only the good guys are the Indians this time.
It is also entirely possible (and no doubt intentional) that the allegorical story can support an interpretation grounded in contemporary conflicts and politics. There's a running anti-corporate theme in Cameron's canon (also found in The Abyss and Aliens), and a seriously pro-green, antiwar tendency - which doesn't stop him from staging epic battles and blowing lots of things up. Avatar isn't just a long setup for a blow-'em-up payoff in the third act; you're meant to care about what happens to Pandora and the Na'vi. Avatar invests in its characters, the good and the bad, creating an engrossing story and a world worth caring about.
