Avatar is a 2009 American science fiction adventure movie. The two main characters are played by Sam Worthington (Jake) and Zoë Saldaña (Neytiri). "Avatar" was directed by James Cameron. In 1994, Cameron wrote an 80-page story about Pandora. He did not start to develop the movie until 12 years later, in early 2006. He did this because the level of technology at the time was not good enough. The cost of the movie was high. It cost $280–310 million to make it and $150 million for marketing. The movie was released in traditional 2-D and 3-D. Only three weeks after it was released (December 18, 2009 in the United States), "Avatar" has earned more money worldwide than any movie other than Cameron's previous movie, "Titanic". In 2014, they announced that there will be a sequel in the 2020s. The Dates are December 2022, 2024, 2026 and 2028.
