Following the massive success of "Avatar", James Cameron announced that multiple sequels for the 2009 blockbuster were in the works. Fans, however, have barely learned anything about the plot details of "Avatar 2" since the project has been so long in development.

Recently, the helmer spilled the beans about the plot details of the second "Avatar" film while talking to Variety about "Toruk", the Cirque du Soleil "Avatar"-inspired show. Cameron revealed that "Avatar 2" would actually be a family saga. "The storyline in the sequels really follows Jake [Sam Worthington] and Neytiri [Zoe Saldana] and their children," he explained. "It's more of a family saga about the struggle with the humans."

Cameron also promised the second film would come out in Christmas 2018. "We haven't moved that target yet, but we will if we need to," he said. "The important thing for me is not when the first one comes out but the cadence of the release pattern. I want them to be released as close together as possible. If it's an annual appointment to show up at Christmas, I want to make sure that we're able to fulfill on that promise."

Production on the second "Avatar" film is expected to begin in 2017, with Stephen Lang and Sigourney Weaver returning to portray their roles from the first film as Colonel Miles Quaritch and Dr. Grace Augustine respectively. It's unclear how the two characters will be involved in the film since both of them died in the first film.

The next three films are scheduled to be released in 2020, 2022 and 2023 respectively.
