After 20+ years of waiting for movie technology to catch up with his vision, James Cameron followed up his unsinkable Titanic with Avatar, a sci-fi epic meant to trump all previous sci-fi epics. Set in the future on a distant planet, Avatar spins a simple little parable about greedy colonizers (that would be mankind) messing up the lush tribal world of Pandora. A paraplegic Marine named Jake (Sam Worthington) acts through a 9-foot-tall avatar that allows him to roam the planet and pass as one of the Na'vi, the blue-skinned, large-eyed native people who would very much like to live their peaceful lives without the interference of the visitors. Although he's supposed to be gathering intel for the badass general (Stephen Lang) who'd like to lay waste to the planet and its inhabitants, Jake naturally begins to take a liking to the Na'vi, especially the feisty Neytiri (Zo Saldana, whose entire performance, recorded by Cameron's complicated motion-capture system, exists as a digitally rendered Na'vi). The movie uses state-of-the-art 3D technology to plunge the viewer deep into Cameron's crazy toy box of planetary ecosystems and high-tech machinery.
