AVATAR

Avatar is a 2009 American science fiction film written and directed by James Cameron, and starring Sam Worthington, Zoe Saldana, Stephen Lang, Michelle Rodriguez, Joel David Moore, Giovanni Ribisi and Sigourney Weaver.

The film is set in the mid-22nd century, when humans are mining a precious mineral called unobtanium on Pandora, a lush habitable moon of a gas giant in the Alpha Centauri star system. The expansion of the mining colony threatens the continued existence of a local tribe of Na'vi—a humanoid species indigenous to Pandora. The film's title refers to the genetically engineered Na'vi-human hybrid bodies used by a team of researchers to interact with the natives of Pandora.

Development on Avatar began in 1994, when Cameron wrote an 80-page scriptment for the film.Filming was supposed to take place after the completion of Cameron's 1997 film Titanic, for a planned release in 1999, but according to Cameron, the necessary technology was not yet available to achieve his vision of the film.

Work on the language for the film's extraterrestrial beings began in Summer 2005, and Cameron began developing the screenplay and fictional universe in early 2006.Avatar was officially budgeted at $237 million. Other estimates put the cost between $280 million and $310 million for production and at $150 million for promotion.The film was released for traditional viewing, 3-D viewing (using the RealD 3D, Dolby 3D, XpanD 3D, and IMAX 3D formats), and "4-D" viewing. The stereoscopic filmmaking was touted as a breakthrough in cinematic technology.

Avatar premiered in London on December 10, 2009, and was internationally released on December 16 and in the United States and Canada on December 18, to critical acclaim and commercial success.

In 2154, the RDA Corporation is mining a valuable mineral called unobtanium on Pandora, a lush, Earth-like habitable moon with an atmosphere poisonous to humans in the Alpha Centauri star system. Pandora is inhabited by the Na'vi, 10-foot (3.0 m)-tall, blue-skinned, sapient humanoids who live in harmony with nature and worship a mother goddess called Eywa.

To learn about the Na'vi and Pandora's biosphere, scientists use Na'vi-human hybrid bodies called avatars that are operated via mental link by genetically matched humans. Jake Sully (Sam Worthington), a paraplegic former marine, replaces his twin brother, a scientist trained as an avatar operator who was murdered in a robbery. Dr. Grace Augustine (Sigourney Weaver), head of the Avatar Program, considers Sully an inadequate replacement and assigns him as a bodyguard.

While protecting the avatars of Grace and scientist Norm Spellman (Joel David Moore) on their expedition to collect biological samples and data in the forest, Jake's avatar is attacked by a jungle predator thanator. Fleeing for his life, Jake strays from the rest of the group and gets lost in the forest. Neytiri (Zoe Saldana), a female Na'vi, stumbles upon Jake and reluctantly rescues him from Pandora's wildlife. Seeing portents from Eywa, she takes him to her clan's dwelling, Hometree; there, Jake meets Neytiri's father, clan chief Eytukan (Wes Studi). Neytiri's mother Mo'at (C. C. H. Pounder), the clan's spiritual leader, orders her daughter to teach the "warrior dreamwalker" their ways.
