Set more than a decade after the events of the first film, Avatar: The Way of Water tells the story of the Sully family (Jake, Neytiri and their children), the troubles that haunt them, the extent of steps they take to stay safe, the battles they fight to stay alive, and the tragedies they endure.

Directed by Canadian filmmaker, screenwriter and producer James Cameron and produced by Cameron and Jon Landau, Lightstorm Entertainment Production's sci-fi film stars Sam Worthington, Sigourney Weaver, Stephen Lang and Kate Winslet.

Zoe Saldaña, who was been part of the production 13 years ago, was cast again in the sequel. 

"I hope it's well received because it certainly was special for me to be a part of this and to have worked with the people that I've worked with to grow old with them, grow with them in this industry with the opportunities that it's opened up for me, but also the conversation that started even for someone like me about the environment,” said the actress in an interview with Good Morning America.

In the sequel to Avatar, Saldaña plays the role of Neytiri, a Na'vi native who teaches Jake about her tribe, but ultimately falls in love with him.

The script for Avatar: The Way of the Water has been written by James Cameron, Rick Jaffa and Amanda Silver. David Valdés and Richard Baneham have served as executive producers of the film.

With Avatar: The Way of Water, the cinematic experience reaches new heights as Cameron transports audiences back to the magnificent world of Pandora in a spectacular and moving action-packed adventure. The film is more than three hours long.

"We didn't spend as much time on the relationship and the emotion in the first movie as we did in the second, and it's a longer movie, because there are more characters to attend to," Cameron explained to CBR.

The sequel to the Academy Award-winning film Avatar, the highest-grossing film of all time, will open in theaters on Dec. 16.
