Production - Themes and inspirations

Avatar is primarily an action-adventure journey of self-discovery, in the context of imperialism and deep ecology. Cameron said his inspiration was "every single science fiction book I read as a kid", and that he was particularly striving to update the style of Edgar Rice Burroughs's John Carter series. The director has acknowledged that Avatar shares themes with the films At Play in the Fields of the Lord, The Emerald Forest, and Princess Mononoke, which feature clashes between cultures and civilizations, and with Dances With Wolves, where a battered soldier finds himself drawn to the culture he was initially fighting against.

The look of the Na'vi—the humanoids indigenous to Pandora—was inspired by a dream that Cameron's mother had, long before he started work on Avatar. In her dream, she saw a blue-skinned woman 12 feet (4 m) tall, which he thought was "kind of a cool image". He included similar creatures in his first screenplay (written in 1976 or 1977), which featured a planet with a native population of "gorgeous" tall blue aliens. The Na'vi were based on them
