Fans eager to watch the Avengers: Doomsday trailer should prepare for a major blockbuster event this holiday season. Marvel Studios has planned an extensive year-long marketing campaign for the film.
Doctor Doom was revealed as the villain for Avengers: Doomsday at San Diego Comic-Con in July 2024, rapidly increasing excitement for the MCU's newest entry. The first teaser surfaced in March 2025 during the notable five-hour chair video unveiling the film's cast.
According to Collider, the teaser trailer will debut exclusively in theaters alongside Avatar: Fire and Ash on December 19, 2025. However, this schedule might still be adjusted by Disney.
If the plan holds, Avengers: Doomsday’s trailer will be shown for almost a full year—364 days—before the movie's official release on December 18, 2026.
While Disney releasing a trailer this early is uncommon, it is not unprecedented. For instance, the first teaser for Star Wars: The Force Awakens was released 13 months before its theatrical debut in November 2014.
"Collider reports that the teaser trailer for the Avengers: Doomsday will be attached exclusively to screenings of Avatar: Fire and Ash on December 19, 2025."
Author's summary: Marvel plans to debut the first Avengers: Doomsday trailer nearly a year ahead of the film’s release, marking a rare and extensive marketing push for the MCU.
