Fans of 'Avatar' have been waiting eagerly for six years for a sequel to the 2009 epic science fiction film, which has been under production since 2014. All these years, fans did not have any clue as to what was delaying the film's release, but now director James Cameron has revealed the reason for the inordinate delay of 'Avatar 2.'

A report in IB Times states that 'Avatar 2' is being filmed in New Zealand and, according to earlier reports, the production and release of the film was delayed owing to lack of technology. Earlier, announcing the release dates of 'Avatar 2' and 'Avatar 3,' Cameron had divulged that the upcoming sequel would feature new creatures as well as scenery in Pandora.

The reports further stated that Cameron may possibly showcase the water ecosystem of Pandora. Therefore, he may require shooting various underwater scenes. According to the director, the reason behind the delay in completing and releasing 'Avatar 2' is the absence of technology necessary to execute his novel ideas. Clapway reports that such technology is yet to develop.

The website further states that while Cameron did not reveal much regarding the manner in which the new technology will add to in 'Avatar 2,' he has actually shared a few details about the highly anticipated upcoming futuristic science fiction movie. According to Cameron, the new technology will help him motion-capture underwater scenes effortlessly.

In addition, the director is also of the view that the restructured motion-capture technology will help show improved facial expressions. Aside from this, a latest lighting system will illuminate the frame featuring Pandora's jungle in a better way.

As of now, fans can only wait and watch how James Cameron's dreams turn into reality with the new technology in the 20th Century Fox's upcoming film 'Avatar 2,' which is scheduled to be released in December 2017.
