Sam Worthington and Zoe Saldana will both be reprising the role of Jake Sully and Neytiri for three Avatar sequels.
Avatar smashed box office records when it was released back in 2009 and fans have been waiting for the sequel to hit the big screen.
There are three sequels in the pipeline, and The Hollywood Reporter says that both Worthington and Saldana will be back.
Talking about the two actors James Cameron said: "Jake Sully is a rare combination of passion, strength, street smarts and soul, which requires a lot from an actor.
"Sam brought to the role a combination of sensitivity, vulnerability and strength.
"Zoe captured every aspect of the character I envisioned, bringing to Neytiri a mix of delicacy, fierceness and incredible physicality. I am beyond pleased they'll be returning with us to Pandora."
Production begins this autumn in New Zealand, with the films scheduled for release in December 2016, 2017 and 2018.
The movie will see Cameron back in the director's chair, while he will also produce alongside Jon Landau.
