Cameron admits that Weaver is "just very serious about her craft. I'm very serious about my craft."
"We kind of meet in that sort of quest for perfection," he says. "She's amazing. She always brings it every time. I mean, you look at her character in the Avatar sequels. She's playing a 15-year-old at the age of 70-ish, 70 plus, and flawlessly."
Weaver portrayed a teenage Na'vi character, Kiri, in Avatar: Fire and Ash and 2022's Avatar: The Way of Water, following her role as Dr. Grace Augustine in the 2009 original.

Cameron previously told PEOPLE that Weaver was "70 and 71 across that period where she was capturing Kiri."
"I mean, she can capture Kiri tomorrow. Nothing's changed," he told PEOPLE in December 2025. "She's a little bit older now, but she just came in a different person. She came in lighter and more open. I mean, she literally looked like she had gotten younger."
According to Cameron, the role was "maybe one of the biggest acting challenges of her career."
"Because in her mind, she had taken herself back to her 14, 15-year-old self," he said. "And by the way, it wasn't all fun and light. It was the darkness of an anxious teenager."
