The first trailer for Marvel’s Avengers: Doomsday is reportedly set to debut this December alongside James Cameron's Avatar: Fire and Ash.
Collider revealed that multiple sources confirmed the initial footage from the MCU's next major team-up will play before Avatar: Fire and Ash. However, this plan might change before the film's theatrical release on December 19, 2025.
Avengers: Doomsday completed filming in September 2025. While plot details remain minimal, the movie will unite the Avengers, Fantastic Four, and original X-Men on the big screen for the first time.
Several actors previously involved in Marvel projects — including Brie Larson, Famke Janssen, Elizabeth Olsen, Charlie Cox, Andrew Garfield, Halle Berry, and Chris Evans — have either denied or avoided confirming their return for Doomsday.
Channing Tatum, reprising Gambit, stated that Avengers: Doomsday will feature moments 50 times bigger than when Wesley Snipes' Blade appeared in Deadpool & Wolverine.
As of the article's publication, Disney had not responded to inquiries about the trailer or additional details.
Summary: The Avengers: Doomsday trailer is expected to launch this December with Avatar: Fire and Ash, promising an unprecedented MCU team-up and massive cinematic moments.
