James Cameron is giving fans a taste of what to expect in the upcoming “Avatar” sequel.

In an interview with Empire, the award-winning director says things are about to get personal between on-screen couple, Jake (Sam Worthington) and Neytiri (Zoe Saldana), who now have an 8-year-old daughter.

And one “critical” scene, a fight between the pair, helps kick off the storyline. “There’s a three-page argument scene between Jake and Neytiri, a marital dispute, very, very critical to the storyline,” Cameron, 64, told the outlet. “I wound up shooting it all from the point of view of the 8-year-old hiding under the structure and peeking in.”

Cameron will also reunite with “Titanic” star Kate Winslet, who will have a new role in the sequel to the record-breaking 2009 blockbuster.

Winslet, according to Cameron, “was a phenomenal collaborator and just so gung-ho” with her new character, Ronal. “She was really excited about doing the water work and at her peak, I think she held her breath for 7-and-a-half minutes – not during the scene but just during the training,” he said. “She was regularly doing 2 or 3-minute scenes, underwater acting and swimming.”

Adding, “She truly embraced the physicality of the character.”

“Avatar 2” is set to hit big screens in December 2020.
