First Look at Avengers: Doomsday Trailer

The first footage from Avengers: Doomsday is scheduled for an unusually early release. According to Collider, its trailer will be shown before screenings of Avatar: Fire and Ash, James Cameron's new Pandora-focused film hitting theaters on December 19, 2025.

Release Timing and Marketing Strategy

This means fans will get a glimpse of Avengers: Doomsday nearly a full year before its official release on December 18, 2026. For comparison, trailers for Avengers: Infinity War and Avengers: Endgame debuted just six months and five months prior to their releases, respectively.

The extended 12-month promotional window may reflect Marvel Studios' strong confidence in the film, while also sparking early buzz and speculation around a project that remains largely shrouded in mystery.

Cast and Character Highlights

Robert Downey Jr. is confirmed to appear. The movie will unite casts from Fantastic Four and Thunderbolts, along with several MCU heroes and legacy X-Men characters.

The complete cast was unveiled during a six-hour livestream in March 2025.

Gambit actor Channing Tatum said, "Avengers: Doomsday could be the biggest film of the decade."
