Fans eager to watch the Avengers: Doomsday trailer will get their first look this holiday season, as Marvel Studios is launching an extensive year-long marketing campaign. The initial trailer is set to debut alongside the biggest movie of the holiday period.
Since the announcement of Doctor Doom as the villain for Avengers: Doomsday at San Diego Comic-Con in July 2024, excitement for the MCU’s newest installment has surged. An early glimpse appeared in March 2025 through a lengthy five-hour casting reveal video.
Collider reports the teaser trailer for Avengers: Doomsday will premiere exclusively in theaters alongside Avatar: Fire and Ash screenings on December 19, 2025. However, Disney might still alter this plan.
If confirmed, this means the trailer will be shown nearly a full year—364 days—before the movie’s theatrical release on December 18, 2026. While uncommon, Disney previously released the first teaser for Star Wars: The Force Awakens 13 months before its premiere in November 2014.
This early trailer release signals a bold approach to building anticipation around the MCU’s next major event film.
Author’s summary: Marvel plans an unprecedented early trailer launch for Avengers: Doomsday, aiming to build a year-long buzz before its December 2026 release.
