Cast

Further information: Fictional universe of Avatar

Humans

• Sam Worthington as Jake Sully, a disabled former Marine who becomes part of the Avatar Program after his twin brother is killed. His military background helps the Na'vi warriors relate to him. Cameron cast the Australian actor after a worldwide search for promising young actors, preferring relative unknowns to keep the budget down. Worthington, who was living in his car at the time, auditioned twice early in development, and he has signed on for possible sequels. Cameron felt that because Worthington had not done a major film, he would give the character "a quality that is really real". Cameron said he "has that quality of being a guy you'd want to have a beer with, and he ultimately becomes a leader who transforms the world".
• Stephen Lang as Colonel Miles Quaritch, the head of the mining operation's security detail. Fiercely loyal to his military code, he has a profound disregard for Pandora's inhabitants that is evident in both his actions and his language. Lang had unsuccessfully auditioned for a role in Cameron's Aliens (1986), but the director remembered Lang and sought him for Avatar. Michael Biehn, who was in Aliens, read the script and watched some of the 3-D footage with Cameron, but was ultimately not cast in the role.
• Sigourney Weaver as Dr. Grace Augustine, an exobiologist and head of the Avatar Program. She mentors Sully and is an advocate of peaceful relations with the Na'vi, having set up a school to teach them English.
• Michelle Rodriguez as Trudy Chacón, a combat pilot assigned to support the Avatar Program who is sympathetic to the Na'vi. Cameron had wanted to work with Rodriguez since seeing her in Girlfight.
• Giovanni Ribisi as Parker Selfridge, the corporate administrator for the RDA mining operation. While he is at first willing to destroy the Na'vi civilization to preserve the company's bottom line, he is reluctant to authorize the attacks on the Na'vi, doing so only after Quaritch persuades him that it is necessary, and the attacks will be humane. When the attacks are broadcast to the base, Selfridge displays discomfort at the violence.
• Joel David Moore as Dr. Norm Spellman, a xenoanthropologist who studies plant and animal life as part of the Avatar Program. He arrives on Pandora at the same time as Sully and operates an avatar. Although he is expected to lead the diplomatic contact with the Na'vi, it turns out that Jake has the personality better suited to win the natives' respect.
• Dileep Rao as Dr. Max Patel, a scientist who works in the Avatar Program and comes to support Jake's rebellion against the RDA.

Na'vi

• Zoe Saldana as Neytiri, the daughter of the leader of the Omaticaya (the Na'vi clan central to the story). She is attracted to Jake because of his bravery, though frustrated with him for what she sees as his naiveté and stupidity. She serves as Jake's love interest. The character, like all the Na'vi, was created using performance capture, and its visual aspect is entirely computer generated. Saldana has also signed on for potential sequels.
• C. C. H. Pounder as Mo'at, the Omaticaya's spiritual leader, Neytiri's mother, and consort to clan leader Eytukan.
• Wes Studi as Eytukan, the Omaticaya's clan leader, Neytiri's father, and Mo'at's mate.
• Laz Alonso as Tsu'tey, the finest warrior of the Omaticaya. He is heir to the chieftainship of the tribe. At the beginning of the film's story, he is betrothed to Neytiri.
