The first trailer for Marvel’s Avengers: Doomsday is reportedly set to premiere this December alongside the release of James Cameron's Avatar: Fire and Ash. According to Collider, multiple sources have revealed that the MCU's next major team-up film will debut its initial footage attached to Disney's latest Avatar installment.
Collider notes this plan is subject to change before Avatar: Fire and Ash hits theaters on December 19, 2025. Avengers: Doomsday is scheduled to open almost exactly one year later, on December 18, 2026.
Disney had not responded to requests for comment at the time of reporting. Filming for Avengers: Doomsday wrapped in September 2025.
Concrete information about the film’s plot is limited, but it is confirmed to unite the Avengers, Fantastic Four, and the original X-Men together for the first time in a movie.
Several actors known from previous Marvel projects, such as Brie Larson, Famke Janssen, Elizabeth Olsen, Charlie Cox, Andrew Garfield, Halle Berry, and Chris Evans, have been either evasive or have denied returning as their characters in Doomsday.
“Avengers: Doomsday will include moments 50 times bigger than when Wesley Snipes' Blade turned up in Deadpool & Wolverine,” said Channing Tatum, who is returning as Gambit.
The highly anticipated Avengers: Doomsday trailer is expected to launch this December with Avatar: Fire and Ash, promising a massive cinematic event uniting major Marvel teams with unprecedented scale and mystery.
