A lot has been said about the upcoming sci-fi movie "Avatar 2" and while the film is still in very early stages of its pre-production, many rumours are surfacing online related to plot details, cast updates and what a Na'vi fan can expect to see in the James Cameron movie.

According to Master Herald, it is reported that "Titanic" director, James Cameron is still circling around with various idea for the sequel to 2009 sci-fi "Avatar." It is also reported that James is now in the discussion with the CGI team so that he can understand how he would carry out the idea that he has on his mind.

Fans have waited for a long time to watch the sequel of epic science fiction film but the delay of the movie is because James Cameron is preparing a special graphic technology that would allow him to create an entire new world underneath the ocean of Pandora.

In 2014, James Cameron said during an interview with RTL that he is busy on the script of "Avatar 2." Cameron added that the team has come up with a software that will help them in designing the new characters and creatures of Pandora.

"You'll see new worlds, new habitats, new cultures. The primary conflict between the human view kind of dominating nature and the Na'vi view of being integrated into nature is the same, but it manifests itself in very different ways," Cameron added.

Goksan Ozman, an artist tasked to design the posters for "Avatar 2" stated that the movie is going to have a darker theme and will deal with the prison. Unfortunately, there is no further details about the look of any creatures, inside or outside the prison.

According to Cinema Blend, James Cameron is working on three "Avatar" movies at the same time and this is causing the delay in "Avatar 2." Apparently, the director is trying to make the films in the franchise that will have parallel or more connected stories.

"Avatar 2" is set for a December 2017 release and the two follow-ups are expected to release in 2018 and 2019.
