However, there are some influences that can be seen in the film, such as:
* Native American cultures: The Na'vi, the indigenous people of Pandora, are inspired by Native American cultures and traditions, particularly those of the Lakota and Cheyenne tribes.
* Environmentalism: The film touches on themes of environmentalism and the importance of preserving nature, a concept that is prevalent in many works of fiction.
* Sci-fi classics: Cameron has cited classic sci-fi films like "Star Wars" and "Dune" as influences on his work.
Therefore, while Avatar is not directly adapted from a book, it draws inspiration from various sources and themes, creating a unique and compelling story.
