Avatar is a 2009 American science fiction epic film written and directed by James Cameron and starring Sam
Worthington, Zoe Saldana, Sigourney Weaver, Michelle Rodriguez and Stephen Lang. The film is set in the
year 2154 on Pandora, a moon in the Alpha Centauri star system. Humans are engaged in mining Pandora's
reserves of a precious mineral, while the Na'vi—a race of indigenous humanoids—resist the colonists'
expansion, which threatens the continued existence of the Na'vi and the Pandoran ecosystem. The film's title
refers to the genetically engineered bodies used by the film's characters to interact with the Na'vi.
Avatar had been in development since 1994 by Cameron, who wrote an 80-page scriptment for the film.[
Filming was supposed to take place after the completion of Titanic, and the film would have been released in
1999, but according to Cameron, "technology needed to catch up" with his vision of the film. In early 2006,
Cameron developed the script, as well as the language and culture of the Na'vi. He said sequels would be
possible if Avatar was successful and in response to the film's success, confirmed that there will be another.
