We Know When the First 'Avengers: Doomsday' Trailer Will Arrive

The first trailer for Avengers: Doomsday is expected to debut in theaters this December, coinciding with another major Disney release. Although the film itself won’t premiere until December 2026, fans may soon catch their first glimpse of the epic Marvel event.

Trailer Release Plan

According to Collider, multiple sources confirmed that the trailer will be shown alongside Avatar: Fire and Ash, the upcoming sequel in James Cameron’s long-running sci-fi saga. If this plan holds, audiences can expect to see Robert Downey Jr. returning as a titanium-masked supervillain on December 19.

Timing and Context

This timing is noteworthy, arriving nearly one year before Avengers: Doomsday hits theaters on December 18, 2026. The release aligns strategically with Disney’s holiday schedule, pairing two of its biggest franchises back-to-back.

Marvel’s Upcoming Lineup

Earlier in the year, Marvel reignited fan excitement by unveiling cast chairs for the massive ensemble film. The reveal hinted at the appearance of familiar faces from 20th Century Fox’s X-Men series, adding to speculation about a crossover of historic scale. With Thunderbolts* and The Fantastic Four: First Steps premiering in 2025, the path to Doomsday is gradually unfolding.

Alan Cumming, set to reprise his role as Nightcrawler, shared that he began filming before the script was even finalized.
