It was made by Lightstorm Entertainment and released by 20th Century Fox on December 18, 2009. The film is set in the year 2154 on Pandora, a fictional Earth-like moon in a distant planetary system. Humans are engaged in mining Pandora's reserves of a precious mineral, while the Na'vi — the sapient and sentient race of humanoids indigenous to the moon — resist the colonists' expansion, which threatens the continued existence of the Na'vi and the Pandoran ecosystem. The film's title refers to the remotely controlled, genetically engineered human-Na'vi bodies used by the film's human characters to interact with the natives.
