Theatergoers are going to have to take in Avatar: Fire and Ash four times to get every possible look they can at the upcoming Avengers: Doomsday. It’s now been confirmed in a new report that four different trailers for the MCU’s big upcoming team-up flick will be playing before James Cameron‘s latest epic. Each week will see a new version introduced before the film, starting with the premiere on December 19. Collider reported back in November that Disney was considering a rollout of the teaser before their latest blockbuster, though it appears their plans are even bigger than originally expected.

Marvel and Disney have yet to comment about the rollout plan, but it’s an ambitious effort that could keep viewers coming out to theaters throughout Fire and Ash’s theatrical run. More importantly, though, it’s designed to help Doomsday dominate the conversation for the first month leading into 2026. The first trailer’s release will mark almost exactly one year from the release of the big crossover on December 18, 2026, and will set the scene for the first proper MCU event film since Avengers: Endgame bowed in 2019. The time between the teaser and the film will be the longest for any Avengers film to date, as the House of Mouse looks to get the ball rolling early. Despite a rocky road from that point until now, anticipation for the project has been sky-high from the moment Robert Downey Jr. ripped off the Dr. Doom mask and stunned everyone at San Diego Comic-Con in 2024.

Most of the details of the crossover have been kept under lock and key for now, save for some of the stars involved and the directors. After steering Marvel’s past cinematic events to historic heights, Anthony and Joe Russo are back at the helm and working with another eye-popping cast. The film’s massive chair stunt earlier this year confirmed that many of the old 20th Century Fox X-Men cast members would be back in the fold, including Patrick Stewart, Ian McKellen, Rebecca Romijn, Alan Cumming, James Marsden, and Kelsey Grammer, alongside the exciting returns of Channing Tatum’s Gambit, members of the Thunderbolts, and the Fantastic Four. MCU veterans Chris Hemsworth, Anthony Mackie, Sebastian Stan, Letitia Wright, Paul Rudd, Simu Liu, Winston Duke, Hannah John-Kamen, Tenoch Huerta Mejía, Lewis Pullman, Danny Ramirez, and Tom Hiddleston were also confirmed.

‘Avatar: Fire and Ash’ Will Look to Top Its Blockbuster Predecessors

Of course, it’s not like Fire and Ash needs help getting people out to theaters. The first Avatar in 2009 set a record as the highest-grossing film of all time, not counting for inflation, with over $2.9 billion globally, and The Way of Water placed third with over $2.3 billion. Sandwiched between them, though, is Endgame at just shy of $2.8 billion. With the promise that Thanos would return after the jaw-dropping Infinity War, the stage was set for an explosive finish to the Infinity Saga, something Doomsday and its follow-up, Secret Wars, in 2027, will look to replicate both at the box office and in terms of paying off what has been a divisive stretch for the MCU.

In the meantime, Cameron’s threequel will ride the hype and attempt to give viewers the most moving and visually stunning installment in his saga to date. Fire and Ash follows up on the natural beauty of the first two films with an adventure that threatens to make Pandora burn. Jake Sully (Sam Worthington) and the Metkayina clan are pitted against the Ash people, now joining forces with Miles Quaritch (Stephen Lang) to engulf the rest of the planet in their flames. Disney is pulling out all the stops to not only market but also shine a light on the technical prowess behind the magic, with a new 20/20 behind-the-scenes documentary featuring Cameron and the cast and crew airing tonight on ABC.
