Avatar had been in development since 1994 by Cameron, who wrote an 80-page scriptment for the film. Filming was supposed to take place after the completion of Titanic, and the film would have been released in 1999, but according to Cameron, "technology needed to catch up" with his vision of the film. In early 2006, Cameron developed the script, as well as the language and culture of the Na'vi. He said sequels would be possible if Avatar was successful, and in response to the film's success, confirmed that there will be another.
The film was released in traditional 2-D, as well as 3-D and IMAX 3D formats. Avatar is officially budgeted at $237 million; other estimates put the cost at $280–310 million to produce and $150 million for marketing. The film is being touted as a breakthrough in terms of filmmaking technology, for its development of 3D viewing and stereoscopic filmmaking with cameras that were specially designed for the film's production.
Avatar opened on December 16, 2009 (and two days later in the US) to critical acclaim and commercial success. It grossed $27 million on its opening day domestically, i.e. in the United States and Canada.[17] On its opening weekend it grossed $77 million domestically and $232 million worldwide. Within three weeks of its release, with a worldwide gross of over $1 billion, Avatar became the second highest-grossing film of all time worldwide, exceeded only by Cameron's previous film, Titanic
