Avengers: Doomsday First Trailer Release Date
The first footage of Avengers: Doomsday is expected to premiere in theaters this December, alongside another major Disney release. Although the movie itself won't hit theaters until December 18, 2026, fans may see a teaser much sooner.
Trailer Debut with Avatar: Fire and Ash
Multiple sources have informed Collider that the initial trailer for the MCU's upcoming team-up film will be shown with the latest Avatar installment, Fire and Ash. If this plan remains unchanged, audiences will get their first look at Robert Downey Jr.'s titanium-masked supervillain starting December 19.
This timing aligns closely with James Cameron's third Avatar film premiere, which releases nearly one year prior to Doomsday.
Setting the Stage for Doomsday
- Thunderbolts and The Fantastic Four: First Steps are premiering this year, paving the way for Doomsday.
- Marvel surprised fans with cast chairs for the blockbuster event earlier this year, revealing unexpected returns including many 20th Century Fox X-Men characters.
Secrecy and Surprises
The details of this crossover remain tightly guarded, even from the actors involved. Alan Cumming, who returns as Nightcrawler, disclosed that filming started before the script was finalized.
"I began filming before the script was finished."
