The long awaited return of the Na'vis will not happen in December 2017 but shooting for the first of three sequels to the phenomenal film starts in April.

Reports have suggested that shooting for the film starts in April 15 in two locations, New Zealand and Manhattan Beach, California. Lead star Sam Worthington, who will reprise his role as Jake Sully, is joined by his love interest Neytiri, played by actress Zoe Saldana in the trilogy.

Actress Sigourney Weaver whose character, Dr. Grace Agustine, died in the previous movie will be back to play a yet unknown character. The actress revealed in The Jonathan Ross Show, "I don't play the same character." However, in another interview with Coming Soon, the actress said "Jim [Cameron] says no one dies in science fiction. He's told me the stories for the next two movies and I have to say that they're absolutely wonderful and there's a real treat in store."

At a press event back in 2010, creator-director James Cameron's teased Weaver's fate, saying, "Who said she died? Nobody dies in a science fiction movie." Cameron is known to be a perfectionist, and though no one in the production has confirmed that his attention to detail could be causing production delays, 20th Century Fox CEO Jim Gianopulos may have hinted at it at a conference in New York.

Variety shares that Gianopulos had visited Cameron's office in New Zealand and said, "It's a room… which is covered floor to ceiling with images, characters, worlds, settings… It's the most amazing, breathtaking thing you've ever seen. His challenge is to put all of that in a movie."

The first "Avatar" movie also went through multiple delays before it was finally shot and eventually shown. The three part sequel will be shot simultaneously and shown one year apart each other. No release date has been announced yet.
