Avatar producer Jon Landau has released new details on what fans can expect will happen in the following three films in the franchise. Most importantly, Oona Chaplin’s role in the upcoming Avatar 3  film.

The granddaughter of Charlie Chaplin and Game of Thrones alum will play Varang. The leader of Varang – the fire-themed Na’vi tribe known as the Ash People, who are eviler and will be the center point of the third installment.

“There are good humans, and there are bad humans. It’s the same thin on the Na’vi side,” Landau told Empire. “Oftentimes, people don’t see themselves as bad. What is the root cause of how they evolve into what we perceive as bad? Maybe there are other factors there that we aren’t aware of.”

Landau announced Avatar 4 would have “a big time jump” before the fifth film and takes place between the moon of Pandora to Earth. The Avatar Earth is similar to ours but is “ruled by over-population and a depletion of our natural resources that make life harder.”

The Avatar team doesn’t “want to paint a bleak picture for where our world is going. The films are also about the idea that we can change course.”

These comments come after the global release of Cameron’s long-awaited sequel Avatar: The Way of Water, released to theaters 13 years after the original epic. Cameron had said that if The Way of Water were to fail at the box office, he would be cautious and consider not releasing the rest of the franchise – despite already wrapping production for Avatar 3 and part of four.
