To record realistic movement, the cast performed in a 250,000-gallon tank. They were trained in free diving; notably, Kate Winslet held her breath for over seven minutes during filming.

Set approximately 16 years after the first film, the story begins with Jake Sully leading a peaceful life as chief of the Omatikaya clan. However, the Resources Development Administration (RDA) returns to colonize Pandora, bringing "recombinants"—Na'vi avatars implanted with human soldiers' memories, including a new version of Miles Quaritch.

The production used the "Deep X 3D" system with submersible lenses to eliminate distortions common in underwater filming.
