《阿凡达》让人震撼的视觉效果

Behind Enemy Lines: With Earth in trouble, humans are off to Pandora - and the native Na'vi are ready to fight for their home. Genetically hybridized and assigned to infiltrate them, combat veteran Jake Sully (Sam Worthington, left) goes native himself when he meets Neytiri (Zoe Saldana).

阿凡达（Avatar）是一部即将上映的3-D科幻电影，由著名导演詹姆斯·卡梅隆执导，二十世纪福克斯出品。该影片预算超过5亿美元，成为电影史上预算最高的电影。官方网站公布本片在中国将于2010年1月2日上映。　

3D电影并不鲜见，但是运用如此之多的CG角色，包括人物、动物、植物，甚至是飞行器、武器系统，同时要在完全虚拟的、想象的空间中实现，不可谓工程不浩大。仅从已经公布的2D影片预告篇画面来看，已经足以带给观众震撼的视觉享受，而如果是3D效果，身临其境感觉必然更加强烈。

You've never experienced anything like Avatar, and neither has anyone else. Its shock-and-awe tactics restore a sense of wonder to the moviegoing experience that has been missing for far too long.
The year is 2154, and Planet Earth is in big trouble - big enough that people are going all the way to Pandora, six light-years away. The Na'vi - blue-skinned, 10-foot (computer-generated) creatures who live on the exotic moon - are not happy about that, which is why the speech the head of human security gives to his forces sounds less like a warning than a death sentence.

Listening to that speech is partially paralyzed combat veteran Jake Sully. He's come to Pandora to become the human mind inside an avatar - a genetically engineered hybrid between humans and the Na'vi. But once hothead Jake crosses the security barrier from the heavily protected base to enter Pandora proper, he can't help but be wowed by the vividness of the fantastical creatures there - flying dragons, anvil-headed rhinos and such.

You'll be wowed too: The creative intensity on display in Avatar is so potent, we're barely troubled by the same weakness for flat dialogue and characterization that put such a dent in Titanic. Those qualities are here, no mistake about that, but because of the nature of the story, they don't matter as much.

That's because to see Avatar is to feel like you understand filmmaking in three dimensions for the first time. In Cameron's hands, 3-D is no forced gimmick. It's a way to create an alternate reality and insert us so seamlessly into it that we feel like we've actually been there.
Avatar may be the most expensive and accomplished Saturday matinee movie ever made. But if spectacle and adventure are reasons you go to the movies, Avatar is something you won't want to miss.
