The reveal of when to expect Avengers: Doomsday‘s first proper trailer has also confirmed that what is arguably the MCU‘s biggest moment of 2025 is set to happen in the year’s final days, making it now just weeks away from happening. The path Avengers: Doomsday has walked thus far has already made it one of the MCU’s most interesting releases – in part because of how much plans for the fifth Avengers movie have changed over the years, taking its story from centering on Kang to centering on Doctor Doom.
Fan curiosity about how the MCU timeline will handle Avengers: Doomsday and its story has been naturally high, with every reveal about the film thus far being the subject of much discussion. These discussions look set to reach a prospective fever pitch of sorts in the coming weeks, as Avengers: Doomsday’s first trailer is reportedly only weeks away from being released, making 2025 an even bigger year for the MCU.
Avengers: Doomsday’s Trailer Release Date Means The MCU Is Closing Out 2025 With Some Huge Reveals

As per Collider, Avengers: Doomsday’s trailer has been revealed to be set for a December 19, 2025 release date – releasing in front of showings of Avatar: Fire and Ash – meaning our first proper look at the fifth Avengers movie will be unveiled in the final days of this year. Given it previously seemed we could be waiting for a fair few months until this sneak peek at what to expect from Avengers: Doomsday, this revelation is especially promising.
While we know some specific details about Avengers: Doomsday already – thanks to both the Avengers: Doomsday cast list that’s been revealed thus far, and thanks to moments like The Fantastic Four: First Steps’ ending teeing us up for what’s to come with Doctor Doom’s first MCU appearance – it’s clear there’s much we have little to no picture of yet when it comes to the major multiversal MCU movie and its story. As such, the first trailer being just over a month away is certainly something to be excited about.
Why Releasing The Avengers: Doomsday Trailer In December 2025 Makes Perfect Sense For The MCU

Prior to the reveal that a trailer for Avengers: Doomsday would be releasing in December 2025, it seemed the franchise would effectively have a gap of sorts in one of the most historically busy times of year for the MCU, since the next actual project to release in the MCU timeline will be Wonder Man in the following January.
With this in mind, unveiling the Avengers: Doomsday trailer in this time period makes particular sense, since it keeps conversations about the franchise alive even while audiences are largely waiting for the next installment in its roster.
Having Avengers: Doomsday’s trailer release before the third Avatar movie also should help to further reinforce the latter film’s own box office results, by encouraging viewers who may have been on the fence about seeing the film in cinemas to go to its theatrical release for the bonus preview of the MCU’s next Avengers movie. In this way, the trailer can build hype for the upcoming arrival of Avengers: Doomsday itself, but also for another major movie that is about to release far sooner than the 2026 MCU film.
