Pakistan, May 6 -- Zoe Saldana is set to deliver what may be the most powerful performance of her career in Avatar: Fire and Ash, according to legendary director James Cameron. With the upcoming instalment in the Avatar saga exploring darker emotional terrain, Cameron has described Saldana's portrayal of Neytiri as "incandescent" and believes it will eclipse even her award-winning role in Emilia Perez. The Titanic and Avatar director, James Cameron, said in an interview with Empire Online that Zoe Saldana's work in Avatar: Fire and Ash defines not just the film, but the emotional soul of the saga itself.

Neytiri's journey takes a darker and more personal turn as tensions mount between the Na'vi and a new tribe known as the Ash People.
