James Cameron’s 2009 film developed under the working title Project 880 was Avatar.
Avatar is a science-fiction film directed and co-written by James Cameron. Its story takes place on Pandora, a fictional moon inhabited by the Na’vi, where humans seek valuable resources and conduct scientific and military operations. The setting explains why the film is sometimes associated with the phrase “Pandora’s box,” but the movie is not an adaptation of the Greek myth.
Project 880 was an early working title used during the film’s development. Cameron had explored the project for years before advances in digital effects and performance-capture technology made production practical. Avatar was released in December 2009 and became a major worldwide commercial success.
The film’s Pandora is therefore a named fictional world, distinct from the mythological woman Pandora and from the 1929 German film Pandora’s Box. Keeping those three references separate avoids a common mix-up created by the shared name.
