=== Casting ===
[[Sam Worthington]] and [[Zoe Saldana]] were confirmed in January 2010 to have signed on to reprise their roles in the sequels. Cameron also stated that [[Sigourney Weaver]] would be featured in all three sequels (the fourth film was not planned at the time) and that her character Grace Augustine would be alive, but it was later revealed she would instead be playing Kiri, Jake and Neytiri's adopted daughter. In August 2017, in an interview with Empire, Cameron revealed that [[Stephen Lang]] would not only be returning in all four sequels but he would also be the main villain in all four films.

In August 2017, [[Matt Gerald]] had officially signed on to portray his first film's role Corporal Lyle Wainfleet in all upcoming sequels. On October 3, 2017, [[Kate Winslet]] had signed on in all four sequels for an unspecified role in the film. Cameron commented, "Kate and I had been looking for something to do together for 20 years, since our collaboration on ''Titanic'', which was one of the most rewarding of my career", and added that her character was named Ronal. On January 25, 2018, [[Dileep Rao]] was confirmed to return as Dr. Max Patel. Winslet commented that her role was "relatively small comparative to the lengthy shoot", as she would only have one month of shootings, but also "a pivotal character in the ongoing story".

In June 2017, [[Oona Chaplin]] joined the cast as Varang, "a strong and vibrant central character who spans the entire saga of the sequels" starting with 3. [[Eiza González]] also auditioned for Chaplin's role. In April 2018, [[David Thewlis]] revealed his involvement in the franchise, stating that he would be featured in three of the four sequels, later stating in January 2020 that his character was a Na'vi. This led to Thewlis being largely reported as part of the cast of ''[[Avatar: The Way of Water]]''; however, he stated in June 2020 that the reports were wrong, and that he would actually be a part of ''Avatar 3'' to ''5''. In 2019, [[Michelle Yeoh]] joined the cast in a live-action role as Dr Karina Mogue.
