The action-packed first trailer for James Camerons next Avatar fantasy epic has leaked online and the footage looks spectacular.

Disney is rolling out the trailer for Avatar: Fire Ash exclusively in theaters in front of Fantastic Four: First Steps. And just like with Christopher Nolans only in theaters trailer for The Odyssey early this month, grainy unauthorized copies have begun to circulate. But give some credit to Disney here the Fire Ash trailer is, at least, a bit tougher to find than the trailer Nolans Universal film was, with copies being taken down as fast as they pop up. Needless to say, fan reaction has been effusive. Fan site The Sietch of Sci-Fi said the trailer looks incredible. Another raved that the trailer was some of the most beautiful footage Ive seen all year [and I was] struck by the real sense of doom and rage fist fights inside of cosmic volcanoes, heroes terrified, huge aerial battles. While another entertainment writer wrote, [The trailer] started out as meh, more of the same and ended with yup, another billion to James Cameron.' And a film critic wrote: The visuals are (somehow) on another level. There is no doubt in my mind that this WILL be the biggest movie of 2025, and epic doesnt feel like it does this trailer justice.

The trailer introduces two new tribes, the Wind Traders and the fire-hurling Ash People clan. The footage shows (trailer spoilers here if thats a thing) plenty of intense arial fighting between Jake Sully (Sam Worthington) and his Navi family, the Ash People clan and, of course, Colonel Miles Quaritch (Stephen Lang, now sporting dramatic white, black and red warpaint, suggesting he might have made an alliance with the Ash People). At one point, a captive Kiri (Sigourney Weaver) is warned by a new villain, Varang (Oona Chaplin), Your goddess has no dominion here. Sully who warns, we cannot live like this is taken captive and paraded by the occupation forces. And Spider (Jack Champion) seems like hes in jeopardy quite a bit.

The first Avatar, released in 2009, became the highest-grossing film of all time, raking in $2.9 billion globally. The first sequel, 2022s The Way of Water, charted as the third-highest-grossing movie of all time (with $2.3 billion), beating expectations and silencing doubters that the Oscar winner could pull off another Avatar blockbuster. At this point, few doubt Camerons ability to generate massive box office returns with the Avatar franchise and confidence is high that Fire Ash will deliver when its released as a major holiday tentpole on Dec. 19.

While a run time hasnt yet been announced, Cameron has teased thatFire and Ashwill be a bit longer thanThe Way of Water. The last film was three hours and 12 minutes.

In a nutshell, we had too many great ideas packed into act one of [Way of Water], Cameron recently said. The [film] was moving like a bullet train, and we werent drilling down enough on character. So I said, Guys, weve got to split it.[Fire Ash]will actually be a little bit longer than[Way of Water].

Cameron plans fiveAvatarfilms and has said he intends to direct them all, as well. Much of the footage, Cameron has said, has already been shot. Avatar 4is set for Dec. 21, 2029, andAvatar 5will arrive Dec. 19, 2031.

Cameron also hopes to adapt the Charles Pellegrino books Ghosts of Hiroshima and Last Train From Hiroshima as soon as his Avatar schedule permits. The film would focus on the true story of a Japanese man during World War II who survived the atomic blast at Hiroshima as well as the explosion in Nagasaki. If it comes to fruition, it would mark Camerons first non-Avatar film since 1997s Titanic.

Fire Ash cast members include Zoe Saldaa, Sigourney Weaver, Britain Dalton, Jack Champion, Trinity Jo-Li Bliss, Stephen Lang, Giovanni Ribisi, Edie Falco, Brendan Cowell, Matt Gerald, Kate Winslet, Cliff Curtis, Bailey Bass, Jemaine Clement and David Thewlis.

The official description ofFire and Ash: Jake and Neytiris family grapples with grief after Neteyams death, encountering a new, aggressive Navi tribe, the Ash People, who are led by the fiery Varang, as the conflict on Pandora escalates and a new moral focus emerges.

Disney had no comment on the leak.
