为什么阿凡达中外星人是蓝色的？
为什么娜美人是蓝色的？詹姆斯卡梅隆在最近的一次采访中回答说他想在阿凡达与娜美人娜提丽间营造一种另类的爱情故事。既然肤色问题”在地球上是非常重要的一个问题“，卡梅隆决定将外星人的肤色作为故事的一个切入点。其他的肤色都已经被各个电影用过了，绿色的肤色在外星人电影中也非常土了。”我们有高大的蓝色女人，而不要绿色小男人。”但是对于为什么娜美人的皮肤会闪光，卡梅隆只字未提，但是每个人都承认那是个很好的效果。
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.
