First trailer for Avengers: Doomsday will be released with Avatar 3
Avatar: Fire and Ash is the biggest Disney film in 2025, and the first teaser trailer for Avengers: Doomsday may be released with it.

Anticipation for the next major Marvel event is already hitting new levels. The film Avengers: Doomsday is officially scheduled to premiere on December 18, 2026, positioning the title as the biggest event of the year for Phase Six of the Marvel Cinematic Universe.
Previously, the film had been slated for a May release, but Marvel Studios moved the date to late December.
The earlier rumor, circulated by scooper Daniel RPK, suggested that the first look or teaser for the film would be released alongside Avatar: Fire and Ash in December 19, 2026.
While the teaser date remains speculation, the confirmed film release in December signals a new, powerful launch strategy for Marvel’s major blockbusters.
The Strategic December Release for Avengers: Doomsday trailer
The December release of Avengers: Doomsday is crucial. Moving the film from the competitive summer window to the year’s end guarantees the directors, the Russo Brothers, more time for the complex post-production and extensive visual effects.
This is especially important because the film will feature a massive ensemble cast that includes characters from the MCU, such as the X-Men and the Fantastic Four.
The film will serve as the gateway to the battle against Doctor Doom, paving the way for the saga’s conclusion the following year with Avengers: Secret Wars (currently set for December 2027).
This strategic choice of a December release places the film in a peak box office period and aligns it with the success of other huge Disney franchises, including Star Wars and Avatar.
The hype continues to build, and the community now awaits confirmation that the first teaser for Avengers: Doomsday will indeed arrive with Avatar: Fire and Ash in December 2026, just months ahead of the official premiere.
