Fans eager to watch the Avengers: Doomsday trailer should prepare for a major event this holiday season. Marvel Studios is launching a year-long marketing campaign for the film, with the debut trailer set to accompany the biggest holiday movie release.
The casting of Doctor Doom was officially announced at San Diego Comic-Con in July 2024, which significantly increased excitement for the MCU's upcoming installment. Initial hints appeared earlier, in March 2025, through a lengthy five-hour chair video unveiling the film’s cast.
It is uncommon, but not unheard of, for Disney to release trailers so far ahead of a movie's premiere. For example, the first teaser for Star Wars: The Force Awakens debuted 13 months before its theatrical release in November 2014.
"The teaser trailer for the Avengers: Doomsday will be attached exclusively to screenings of Avatar: Fire and Ash on December 19, 2025."
Such an early release strategy aims to build long-term anticipation ahead of the film's debut.
Author's summary: Marvel is set to launch the Avengers: Doomsday trailer nearly a year before its release, marking an unusually long promotional period ahead of the December 2026 premiere.
