Avatar: Fire And Ash London premiere

Sigourney Weaver led the stars at the Avatar: Fire And Ash UK premiere in London on Thursday night, reported the Daily Mail.

The actress, 76, who plays Grace Augustine in the franchise, looked elegant in a velvet black gown as she joined Stephen Lang and Oona Chaplin on the red carpet at at BFI IMAX Waterloo.

Oona, who portrays a Na'vi leader named Varang in the film, stunned in a black sheer lace gown while villain Stephen put on a dazzling display in a glittery navy blazer.

Avatar: Fire and Ash marks the third entry in James Cameron's long-planned series, following the record-breaking original film of 2009 and the 2022 sequel Avatar: The Way of Water.

And the premiere drew in a huge crowd of television personalities, sports stars and models.

Sabrina Elba, 36, looked effortlessly sophisticated in a white dress as she made a solo appearance on the red carpet, while her husband Idris attends the Red Sea Film Festival in Saudi Arabia.

Written by James alongside Rick Jaffa and Amanda Silver, the film continues the saga of Jake Sully and Neytiri as they navigate new threats to their family and their world.

The film introduces a major new dynamic: the emergence of the Ash People, also known as the Mangkwan Clan.

Unlike the sea-dwelling Metkayina of The Way of Water, the Ash People occupy a once-hidden corner of Pandora's ecosystem, one shaped by fire, volcanic landscapes, and harsh survival.

At the forefront of this new tribe stands Varang. Early descriptions paint her as a fierce, calculating leader who is willing to take extreme measures to secure the future of her people.

A synopsis for the flick reads: 'Jake and Neytiri's family grapples with grief after Neteyam's death, encountering a new, aggressive Na'vi tribe, the Ash People, who are led by the fiery Varang, as the conflict on Pandora escalates and a new moral focus emerges.'

While Fire and Ash is intended to conclude the first major arc of the Avatar saga, it is far from the final film — James has already outlined plans for Avatar 4 and Avatar 5.

Avatar: Fire and Ash will hit UK cinemas on December 19.

The original Avatar's road to box office history was an unusual one, with most top-grossing films accomplishing this with top-loaded massive opening weekends.

Avatar's success ($2.92billion) was largely due to consistent viewings at a level rarely seen at the box office and still remains the highest grossing movie of all-time.

Filmmaker James, 71, said of the 2025 sequel: 'The fire will be represented by the 'Ash People.' "I want to show the Na'vi from another angle because, so far, I have only shown their good sides.

"In the early films, there are very negative human examples and very positive Na'vi examples. In Avatar 3, we will do the opposite.

"We will also explore new worlds, while continuing the story of the main characters,' he said. 'I can say that the last parts will be the best.

"The others were an introduction, a way to set the table before serving the meal."
