Why are the Na'vi blue? James Cameron answered the question in a recent interview saying he wanted there be an "otherness" to the love story between Sully's avatar and the native alien, Neytiri. Since skin color is "such a big issue on our planet," Cameron decided to use that issue as a thematic driving point. Other skin tones were already taken by humans, while green was already a cliché in other alien movies. "We had big blue women, not little green men," Cameron said. No word on why the Na'vi's skin sparkles, but you have to admit it is a cool effect.
Meanwhile, the Houston Press' Hair Balls blog has video clips of other blue-skins that have come before AVATAR.Sponsored by Panasonic VIERA. Return to the world of AVATAR in stunning full HD with the Panasonic VIERA HD TV.
