We’ll allow you one sentence just to reiterate: Sigourney Weaver plays a blue teenage alien in Avatar: The Way Of Water. For the actress, who also worked with Cameron all those years ago on Aliens, it was a chance to bring her inner child out to play. “I think we all pretty much remember how we felt as teenagers,” she tells Empire. “Of course I do. I was 5′ 10″ or 5′ 11″ when I was 11. I strongly felt that Kiri would be uncomfortable a lot of times. She is searching for who she is. I was thrilled to be given this challenge by Jim.” Cameron knew exactly what a leap it would be for the legendary actor. “As an acting challenge, it’s a big one,” he says. “We will have a 60-year-old actor playing a character [decades younger than] her actual biological age. Sig thought it was all kinds of fun.” Getting into that mindset meant Weaver workshopped a group of teenage girls to channel some youthful energy – and the results were remarkable. “Sigourney just got younger,” Cameron recalls. “She looked younger, had more energy, and never left Kiri’s side the whole time of conception. She had a sparkle in her face and a lightness in her step and a fun spirit.” While the reveal of Weaver’s role raises all sorts of other questions about what The Way Of Water has in store, one stands out the most: does this mean her mother, Neytiri, will inherit Ripley’s most famous streak? We’ll have a few months to wait and find out what “Get away from her, bitch!” translated into the Na’vi language.
