James Cameron reveals more details on the new tribes in Avatar: Fire and Ash
Varang, the leader of the Ash Clan, is played by Oona Chaplin, arguably known best for her role as Talisa in Game of Thrones. "I didn't quite appreciate how good her performance is until we got the Wētā animation back," Cameron said, praising the actress. "She's an enemy, an adversarial character, but [Chaplin] makes her feel so real and alive."
