Sigourney Weaver will play a teenager in Avatar 2

Hollywood icon Sigourney Weaver added another big role to a very long list when she appeared as Dr. Grace Augustine in 2009’s Avatar, currently the highest-grossing movie of all time. Her character died partway through the movie, so fans were a little confused when it was announced that she would also appear in the upcoming sequel, Avatar: The Way of Water. Now we’re finding out more details.

According to Empire, Weaver won’t be playing Dr. Grace Augustine. Instead she’ll play a wholly new character: a Na’vi teenager named Kiri, the adopted daughter of Jake Sully (Sam Worthington) and Neytiri (Zoe Saldana).

Weaver is 72 years old, so it’s been a minute since she’s been a teenager. She’s not worried, though. “I think we all pretty much remember what we were feeling as adolescents,” she said. “I certainly do. I was 5’ 10” or 5’ 11” when I was 11. I felt strongly that Kiri would feel awkward a lot of the time. She’s searching for who she is. I was thrilled to be given that challenge by [director James Cameron].”

At least it’ll be hard to mistake Weaver’s new character for Dr. Grace, since the Na’vi aliens are created mainly using motion capture technology and special effects. Although I wonder if this teenage role wouldn’t be better off in the hands of…well, a teenager. But I can reserve judgment.

Kate Winslet teases her Na’vi character in Avatar: The Way of Water

Kate Winslet will also play a Na’vi alien in the new movie; she told Empire that her character Ronal is “”deeply loyal and a fearless leader.”

Avatar: The Way of Water will come out on December 16 of this year.
