Multiple “Avengers: Doomsday” leaks have surfaced over the past weeks, suggesting that Marvel plans to attach the film’s inaugural teaser trailer to “Avatar: Fire and Ash.” Initially, reports indicated that the clip would be released on December 11, but that date was later postponed to December 19. Furthermore, the number of rumored “Doomsday” teasers has grown from one to four. A new teaser is expected to premiere in front of “Fire and Ash” weekly, likely aimed at building excitement for Marvel’s largest crossover film since “Avengers: Endgame,” which is set for release on December 18, 2026. Days prior to the “Avatar: Fire and Ash” release, descriptions of the four “Doomsday” trailers have leaked, and as of this writing, at least one has made its way online.
The anticipated trailer promotional campaign for “Doomsday” shouldn’t astonish long-time fans of the Marvel Cinematic Universe (MCU). In late March, Marvel hosted a five-and-a-half-hour livestream on YouTube for the upcoming “Avengers” film, showcasing a new chair with a cast member’s name every few minutes. Marvel announced a total of 27 actors set to star in “Avengers: Doomsday,” and Robert Downey Jr., portraying the film’s primary antagonist, Doctor Doom, made a live appearance. This event generated 3.1 million mentions across social media and amassed 275 million views, according to Marvel.
What’s intriguing about the initial “Avengers: Doomsday” teaser trailer is that Marvel has chosen to reveal a significant spoiler—one that many filmgoers may have anticipated. It’s unlikely that anyone will escape this revelation, but if you’re looking to avoid spoilers or wish to maintain an element of surprise before the “Avatar” premiere this week, you should skip the details that follow.
Avengers: Doomsday trailer release schedule
A few days ago, The Hollywood Reporter mentioned in a newsletter that “Avengers: Doomsday” would unveil four trailers during the theatrical run of “Avatar 3.” Several prominent Marvel insiders teased the four clips and provided additional details online as low-quality footage of the first trailer leaked. If the information holds true, each of the initial three clips will concentrate on a specific character, one of which will spotlight Doctor Doom. However, RDJ’s significant reveal will not happen in the first clip. That’s the major twist Marvel has in store for audiences.
The first teaser will spotlight none other than Steve Rogers (Chris Evans), the MCU’s original Captain America, who was last seen at the conclusion of “Endgame,” retiring in an alternate reality with Peggy Carter (Hayley Atwell). Marvel did not mention Evans’ name during the livestream. He has been refuting rumors regarding his return to the MCU since 2019. The clip is already making rounds on social media, with Marvel quickly removing it through copyright claims as fast as it appears. Interestingly, someone utilized AI tools to recreate a portion of the first trailer and enhance it to 4K. That version of the trailer remains available online.
The second teaser is expected to highlight Thor (Chris Hemsworth), the second of the MCU’s big three and “Avengers” stars. The trailer is set to release in “Avatar 3’s” second week in theaters, around December 25. The third character-focused “Doomsday” trailer will feature Doctor Doom, with Marvel planning to launch it a week later, approximately on January 2nd. Finally, rumors suggest that the fourth “Doomsday” trailer will debut in the fourth week, or around January 9th. This should be the first complete “Doomsday” trailer.
How to watch the Avengers: Doomsday trailers online
Marvel’s “Doomsday” trailer promotion serves a dual purpose aside from creating hype. It aims to encourage more moviegoers to purchase tickets to see “Avatar: Fire and Ash” multiple times, which will benefit Marvel’s parent company, Disney. However, you need not be concerned about rewatching James Cameron’s film multiple times merely to catch the brief trailers featuring your favorite Avengers.
As demonstrated by this week’s developments, the trailers are bound to leak online, either prior to their theatrical debut or once they begin airing with “Fire and Ash.” It is relatively straightforward to locate the leaked trailers, despite Marvel’s persistent efforts to remove them. Nevertheless, you should be cautious not to fall for fake, AI-generated “Doomsday” clips, which are also circulating.
At this moment, it’s uncertain when Marvel will publish the four trailers online. The studio may choose to wait until all four trailers have hit theaters before uploading them to YouTube, but this is purely speculation based on the statements from leakers. There has been no official announcement from the studio thus far.
