Avatar (2009 film) title refers to a genetically engineered Na'vi body operated from the brain of a remotely located human that is used to interact with the natives of Pandora. Development of "Avatar" began in 1994, when Cameron wrote an 80-page treatment for the film. Filming was supposed to take place after the completion of Cameron's 1997 film "Titanic", for a planned release in 1999, but, according to Cameron, the necessary technology was not yet available to achieve his vision of the film. Work on the language of the film's extraterrestrial beings began in 2005, and Cameron began developing the screenplay and fictional
Avatar (2009 film) were based on them. For the love story between characters Jake and Neytiri, Cameron applied a star-crossed love theme, and acknowledged its similarity to the pairing of Jack and Rose from his film "Titanic." An interviewer stated, "Both couples come from radically different cultures that are contemptuous of their relationship and are forced to choose sides between the competing communities." Cameron felt that whether or not the Jake and Neytiri love story would be perceived as believable partially hinged on the physical attractiveness of Neytiri's alien appearance, which was developed by considering her appeal to the all-male crew of artists.
