In 1994, director James Cameron wrote an 80-page scriptment for Avatar. In August 1996, he announced that after completing Titanic, he would film Avatar, which would make use of synthetic, or computer-generated, actors. The project would cost $100 million and involve at least six actors in leading roles "who appear to be real but do not exist in the physical world". Visual effects house Digital Domain, with whom Cameron has a partnership, joined the project, which was supposed to begin production in the summer of 1997 for a 1999 release. However, Cameron felt that the technology had not caught up with the story and vision that he intended to tell. He decided to concentrate on making documentaries and refining the technology for the next few years. It was revealed in a Bloomberg BusinessWeek cover story that 20th Century Fox had fronted $10 million to Cameron to film a proof-of-concept clip for Avatar, which he showed to Fox execs in October 2005. In February 2006, Cameron revealed that his film Project 880 was "a retooled version of Avatar", a film that he had tried to make years earlier, citing the technological advances in the creation of the computer-generated characters Gollum, King Kong, and Davy Jones. Cameron had chosen Avatar over his project Battle Angel after completing a five-day camera test in the previous year.
Origins
From January to April 2006, Cameron worked on the script and developed a culture for the film's aliens, the Na'vi. Their language was created by Dr. Paul Frommer, a linguist at USC. The Na'vi language has a vocabulary of about 1000 words, with some 30 added by Cameron. The tongue's phonemes include ejective consonants (such as the "kx" in "skxawng") that are found in the Amharic language of Ethiopia, and the initial "ng" that Cameron may have taken from New Zealand Māori. Actress Sigourney Weaver and the film's set designers met with Jodie S. Holt, professor of plant physiology at University of California, Riverside, to learn about the methods used by botanists to study and sample plants, and to discuss ways to explain the communication between Pandora's organisms
