    "The film is not a sophisticated expression of an intellectual, but a sincere outburst from an ordinary man, with simple metaphor," Lu wrote in his blog.

    With the mix of live-action dramatic performance, computer-generated effects and 3-D presentation, Avatar has also set the technical world on fire.

    "My inspiration is every single science fiction book I read as a kid," Cameron, who started moulding the movie in 1994, once told media in an interview.

    "To be certain, I wanted a film that could encompass all my interests, from biology, technology, the environment -- a whole host of passions," he said.

    Due to Cameron's persistence and patience, Avatar, having suffered production delays and fierce criticism for its floating budget, which was reportedly over 300 million dollars overall, eventually became one of the highest-grossing film of all time. Though someone thought the story was lack of creativity, Avatar gained most critics' favor.

    It was reported in the United States that 83 percent of 233 professional critics had given the movie a positive review.

    "Embrace the movie -- surely the most vivid and convincing creation of a fantasy world ever seen in the history of moving pictures," said Richard Corliss of TIME Magazine.

    Winning 11 Oscars, Cameron's Titanic has proved a legacy. Analysts say Avatar may surprise the world again when next Award Academy ceremony commences.
