Approximately 10+ uses of profanity including 's--t', 'damn', 'hell', 'ass', 'SOB', 'bitch', and 'crap'. One or two uses of 'GD' or near-equivalents. Colonel Quaritch uses coarse military language throughout. Sigourney Weaver's character uses 's--t' and 'damn' multiple times.
Extensive military combat sequences with explosions, gunfire, and arrows striking soldiers. Characters are killed by gunfire, crushing, and falls. A massive battle sequence involves the wholesale destruction of the Na'vi Hometree, killing many civilians including implied children. Creatures attack and are attacked throughout. A character is fatally shot with arrows. Colonel Quaritch is stabbed and killed. Animals are shown being injured and killed in battle. Some blood shown but not excessively graphic.
Jake and Neytiri share a romantic/mating scene under a glowing tree. The scene is brief but clearly implies sexual union (they intertwine their neural 'queues' and embrace). This occurs outside of marriage in a traditional sense, though presented as a sacred Na'vi bonding. Na'vi females wear minimal clothing throughout the film — essentially loin coverings and beaded necklaces across the chest, with much of their bodies exposed. While they are alien creatures, the Na'vi females are designed with human-like female anatomy.
The Na'vi religion is a central element of the film. They worship 'Eywa,' a goddess-like planetary consciousness/deity connected to all living things through a biological neural network. This functions as a pantheistic/animistic religion. Characters pray to Eywa, perform rituals at sacred trees, and commune with the spirits of ancestors through a biological connection. Eywa ultimately intervenes in the final battle by sending creatures to fight. Jake undergoes a spiritual transfer of consciousness from his human body to his avatar body through a ritual at the Tree of Souls. This closely parallels New Age and Eastern mystical concepts of interconnectedness, Mother Earth worship, and consciousness transfer.
Sigourney Weaver's character Dr. Augustine is shown smoking cigarettes in several scenes and references wanting a cigarette. Brief social drinking scenes. No drug use per se, though the avatar link pods could be seen as altered-consciousness devices.
Na'vi characters (male and female) wear minimal tribal clothing throughout the entire film, exposing most of their bodies. While they are alien beings, the female Na'vi are designed with clearly feminine human anatomy. Their breasts are covered by thin beaded straps. Jake's human body is shown shirtless. One brief scene of Jake's bare backside when he first emerges from the avatar pod.
A few uses of 'Oh my God' and 'God damn.' The film's overall spiritual framework replaces the God of the Bible with a pantheistic nature deity, which some Christians consider a form of theological blasphemy.
Themes of self-sacrifice, protecting the vulnerable, standing up against greed and injustice, loyalty, and courage. Jake risks everything to defend an innocent civilization against corporate exploitation. The film portrays respect for creation and living things. However, these positive values are embedded within a pantheistic/animistic worldview rather than a Biblical one.
In the 22nd century, a paraplegic Marine is dispatched to the moon Pandora on a unique mission, but becomes torn between following orders and protecting an alien civilization.
