"Avatar 2" fans, who have been waiting for almost six years now, finally are in for some interesting updates on the most-awaited CGI movie with producer Jon Landau releasing new "Avatar 2" artwork. Also, according to the latest buzz, Sigourney Weaver would reprise her original role from the first "Avatar" as Dr. Grace Augustine.

The sequel of the popular futuristic sci-fi epic has been under production since 2014. But now, some regular production updates and plot speculations like the film's theme and set-up have kept fans' doubts in check.

According to new reports, the film will bring back the character of Dr. Grace Augustine (Sigourney Weaver), who died in the first movie. The report said that there's no confirmation on how this will be included in the script, but chances are that Augustine will have a new avatar.

Meanwhile, producer Jon Landau has given fans a sneak-peek into the character of the upcoming "Avatar 2" film. The producer took to Twitter to reveal the brand new artwork that teases the features of the face of a female Avatar character.

He captioned it: "Avatar 2".

Back in July, at the Siggraph conference, the producer had hinted that the team is working to pay a lot of attention to characters' details. And he assured that the sequel's characters and storyline will be more complex compared to the earlier "Avatar" movie.

As of now, various reports have suggested that "Avatar 2" will have a prison theme, and focus on new creatures, underwater sceneries and the ecosystem of Pandora.

In addition to all this, James Cameron has earlier said that, "We're writing three films simultaneously. And we've done that so that everything tracks throughout the three films. We're not just going to do one and then make up another one and another one after that and parallel with that, we're doing all the design. So we've designed all the creatures and the environments."

20th Century Fox's "Avatar 2" will be released in December 2017. "Avatar 3" and "Avatar 4" are expected to be released in 2018 and 2019, respectively.
