First Avengers: Doomsday Trailer Expected in December
Avengers: Doomsday will likely debut its first footage in theaters this December, paired with a major Disney release. Although the film itself hits theaters in December 2026, fans may see a teaser soon.
Trailer to Accompany Avatar: Fire and Ash
Sources tell Collider the initial footage for this major MCU team-up will be shown alongside the new Avatar: Fire and Ash movie. If plans stay unchanged, audiences will get their first look at Robert Downey Jr.'s titanium-masked villain on December 19.
The timing matches well since James Cameron's third Pandora film releases almost exactly one year before Doomsday’s December 18, 2026 premiere.
Setting the Stage with New Marvel Projects
This year, Marvel laid the groundwork with premieres of Thunderbolts and The Fantastic Four: First Steps, preparing audiences for the epic crossover. Earlier, the cast reveal sparked excitement, especially with many 20th Century Fox X-Men returning.
Secrecy around the Project
Marvel remains tight-lipped about the film’s details, even the cast is kept in the dark. Alan Cumming, reprising Nightcrawler, shared he started filming before the final script was ready.
Author’s Summary
Avengers: Doomsday’s first trailer is set to release in December 2025, teasing a highly anticipated Marvel crossover arriving the following year.
