20th Century Fox had originally given Avatar 2 a December 2014 release date with Avatar 3 hitting a year later in December 2015, however while speaking at a screening of Titanic 3D producer Jon Landau said “it will be four or so years” before the second film will be released.
Assuming he’s got his numbers right, that means James Cameron and the team are now aiming for either December 2015, or 2016. In order to have hit the original 2014 release filming would have had to begin sometime this year, but in a recent interview Sam Worthington said Cameron still hasn’t got a complete script and he’s trying to “push the boundaries” in regards to the technology, which could be one of the reasons for the delay.
Cameron has previously revealed the sequels to Avatar would be “focusing on the oceans on Pandora, which will be equally rich and diverse and crazy and imaginative” as the rain forest environment we saw in the first film. This will require some underwater performance-capture, which has never been done before. Cameron is also planning to shoot at 60 frames per second which, again, has never been done before on a feature film.
The sequels will be shot back-to-back so whenever the second film hits, the third won’t be far off.
