Director James Cameron mesmerized audiences with his film “Avatar” back in 2009. The film was initially planned for a 1999 release after Cameron’s last movie, “Titanic” in 1997, but was delayed for a decade due to the lack of technology needed for the film to proceed. It was worth the wait though, as “Avatar” was praised by critics for its stunning visuals and masterful storytelling. The film was also a box office success, to say the least, as the film earned more than a billion dollars worldwide.

After years of waiting, fans of the first film have a reason to rejoice as the sequel for “Avatar” reportedly started production and is scheduled to be released in December 2020.

Until then, here are a few things you need to know about “Avatar 2.”

Old and new cast members who will be joining the ‘Avatar’ sequel

Fans of the first film will be looking forward to seeing their favorite characters on the big screen once again, which is why the movie will be bringing back Sam Worthington and Zoe Saldana to reprise their roles as Jake Sully and Neytiri, respectively, according to a report by Screen Rant.

Furthermore, Stephen Lang and Sigourney Weaver will also be returning for the sequel despite their character deaths in the first film.

The new actors that will be joining the sequel include Cliff Curtis from “Fear the Walking Dead,” who will be playing the role of Tonowari, and Oona Chaplin, who is best known for her character as Talisa, Robb Stark’s wife, in “Game of Thrones.” Chaplin will reportedly be playing the role of Varang.

The storyline of ‘Avatar 2’

According to Screen Rant, the sequel takes place eight years after the events of the original film, which is why it’s safe to assume that Jake and Neytiri may have already produced an offspring of their own that could play a significant role in the upcoming movie.

Cameron initially stated that he wanted to expand the “Avatar” universe to other moons of Polyphemus.

However, this has been changed and the storyline will remain on Pandora instead, particularly on Pandora’s ocean. Cameron reportedly created a new technology specifically for underwater motion capture, which is why it took this long for the sequel to begin production according to reports.

Lastly, Screen Rant stated that there will be a total of four sequels in the works and all will be shot in 3D. After the 2020 release of “Avatar 2,” further sequels are expected to be released in 2021, 2024 and 2025.
