Seems that making the highest grossing film of all time wasn¡¯t enough for James Cameron. The Academy Award winning director has confirmed that he is working on three more sequels to the Sci-fi groundbreaking film Avatar.

In a press release, Cameron announced dates for the next three films, starting with Avatar 2 being scheduled for released in December 2016. It will be followed by Avatar 3 in December 2017 and Avatar 4 in December 2018. Filming for the sequels will begin shooting next year.

Cameron also revealed that he has recruited a team of super screenwriters to collaborate alongside him on the scripts. This list includes a host of writers with Sci-fi knowledge, such as Josh Friedman (War Of The Worlds and the Terminator: Sarah Connor Chronicles TV series), Rick Jaffa and Amanda Silver (Rise Of The Planets Of The Apes) and Shane Salerno (Savages, Salinger).

Initially only two sequels were planned, making Avatar a trilogy. However, Cameron admitted last year that he was interested in making a fourth Avatar film that would possibly be a prequel.

At the time he said: ¡°It¡¯s a logical thing to do because we¡¯ll have completed the thematic arc by the end of Avatar three. The only thing left to do is go back to see what it was like on those first expeditions and create some new characters that then become legacy characters in later films. It¡¯s a plan.¡±

Cameron has since confirmed that there will be a fourth film, and in the statement release, he explained his reasons. ¡°Building upon the world we created with Avatar has been a rare and incredibly rewarding experience,¡±

In writing the new films, I¡¯ve come to realise that Avatar¡¯s world, story and characters have become even richer than I anticipated, and it became apparent that two films would not be enough to capture everything I wanted to put on screen,¡±

¡°And to help me continue to expand this universe,¡± he continued, ¡°I¡¯m pleased to bring aboard Amanda, Rick, Shane and Josh ¨C all writers I¡¯ve long admired ¨C? to join me in completing the films¡¯ screenplays.¡±

Stars of the original, including Australia¡¯s Sam Worthington, Zoe Saldana and Sigourney Weaver (who was killed in the first film, but somehow will be resurrected) are all expected to return for the sequels.

Release in 2009, Avatar became the highest-grossing movie of all-time, a title it still holds, with worldwide box office takings exceeding $2.7 billion.
