The first glimpse of Avengers: Doomsday will arrive earlier than fans anticipated. According to Collider, the trailer is set to be shown exclusively before screenings of James Cameron’s upcoming film Avatar: Fire and Ash.
Cameron’s third installment, which explores the world of Pandora’s Ash People, will debut in cinemas on December 19. This means that Marvel’s highly awaited Doomsday trailer will appear nearly one year before the movie’s official release on December 18, 2026.
Previous Avengers movies followed a shorter promotional schedule: Infinity War released its first trailer about six months before premiere, while Endgame revealed its first footage just five months in advance, showing only brief moments from the opening act.
Whether Marvel’s extended 12-month rollout shows higher confidence in Doomsday remains uncertain, but it is likely to ignite intense fan debates and theories about the film’s direction and storyline.
What is confirmed so far is that Robert Downey Jr. returns, alongside the casts of Fantastic Four and Thunderbolts. These teams will unite with various established Marvel Cinematic Universe heroes and several legacy X-Men characters.
The full cast list was unveiled in March during a six-hour live stream, building major excitement across fandoms.
Adding to the buzz, actor Channing Tatum, who plays Gambit, recently stirred further anticipation by suggesting that Avengers: Doomsday might become “the biggest film of the decade.”
The early debut of the Avengers: Doomsday trailer before Avatar: Fire and Ash marks Marvel’s bold strategy to fuel a long, year-long anticipation for its most ambitious crossover yet.
