James Cameron has confirmed that there will now be three sequels to his 2009 movie Avatar, to form a four-film storyline. These films will be shot back-to-back and released in December 2016, 2017 and 2018 respectively. Cameron has hired new writers to help him get the three scripts ready in time.
Previously, Cameron had suggested there would be two sequels and locations visited would include Pandora's oceans and other moons in the same system. However, his ambitions for the sequels have grown larger, requiring three full movies to explore.
Avatar was released in December 2009 and is the highest-grossing movie of all time, making just under $2.8 billion worldwide. A limited run for the extended edition of the film plus DVD and Blu-Ray sales have extended that to well over $3 billion worldwide.
