Sigourney Weaver on Kiri’s Mystique and Reuniting with Cameron

Sigourney Weaver makes her return to Pandora in Avatar: Fire and Ash, stepping into the shoes of Kiri, a Na’vi with a rather unusual origin. Born from Dr Grace Augustine’s Avatar and later adopted by Jake Sully and Neytiri, Kiri is a child marked by her extraordinary abilities. She can communicate with the planet’s creatures and even perform feats that border on the miraculous, yet she remains in the dark about her father’s identity. The story follows Kiri as she begins to understand her unique bond with Eywa, the spiritual force at the heart of Pandora, and finds herself drawn into the turmoil that threatens her world.

Weaver reflects on her experience working once more with director James Cameron, a creative partnership that stretches back to their days on Aliens in 1986. She describes Cameron’s approach as one that gives actors space to uncover their characters in their own time.

‘He doesn’t give you much direction at the start,’

she notes, adding that the process is all about discovery and experimentation on set. For Weaver, this method is a rare treat, allowing her to fully inhabit her role without feeling boxed in.

Returning to Pandora: A New Challenge

Taking on the part of Kiri presented its own set of challenges, not least because Weaver is playing a character far younger than herself. She jokes about the age gap, but is quick to point out the emotional complexity that Kiri brings to the story. The film delves into themes that are deeply human—grief, trauma, and the struggle to break free from cycles of violence. Cameron, she says, is keen to explore how these experiences shape the characters and their relationships.

Weaver’s portrayal of Kiri is layered with vulnerability and strength, as the character navigates her place within her adoptive family and the wider Na’vi community. The mystical elements of Kiri’s journey are balanced by the very real emotions she faces, making her story both otherworldly and relatable.

Collaboration and Creative Freedom

Working with Cameron again has been a highlight for Weaver, who appreciates the director’s willingness to let actors take risks.

‘It’s a dream job for any actor,’

she remarks, emphasising the sense of trust and creative freedom on set. This collaborative spirit has allowed Weaver to bring new depth to Kiri, a character who is still discovering her own identity amid the chaos unfolding on Pandora.

As the release date approaches, anticipation is building among audiences eager to see how Kiri’s story unfolds. The film promises to offer not just visual spectacle, but a thoughtful exploration of loss, resilience, and the search for belonging.
