Christmas has come early for Marvel fans after the first details on several trailers for Avengers: Apocalypse disclosed online.
Last weekend (December 13/14), rumors were rife that the comic book giant would release four (!) teasers for its highly anticipated superhero film. These emerged following speculation that Marvel would only release one single. doomsday trailer before the end of 2025, that it would be released before public screenings of Avatar: Fire and Ashand that the Avengers 5 the trailer’s runtime has reportedly been revealed.
Now, new details have emerged about these teasers. According to media Feature First, each preview will be shown before Avatar 3 for one week only over the next four weeks. So, teaser #1, which will debut alongside Fire and ashes when it arrived on December 17, it would be available until December 23. Then, teaser #2 would be released from December 24 to 30, and so on.
Clearly, Marvel and its parent company Disney are aiming to generate more hype – if more was needed – for the arrival of the Marvel Phase 6 movie. Of course, by exclusively showing the trailers before Avatar 3 will also help strengthen Disney’s bottom line because it will persuade the general public to watch Fire and ashes several times in order to see the four teasers.
This would be the case if information about these trailers hadn’t already appeared online. Despite Marvel and Disney’s best attempts to mitigate leaks, the sheer number of theaters that previews will have been sent to means that keeping them under wraps is nearly impossible. Eventually, someone somewhere was going to reveal everything – and that’s exactly what happened here.
I will not post links to hacked images or screenshots from the first teaser. However, given that Marvel has issued numerous DMCA takedowns to anyone who posted these files online, it’s clear that they are authentic.

Still with me? Well, now you will know that Chris Evans East back as Steve Rogers in Avengers: Apocalypse.
In December 2024, it appeared that doomsday brought back another Marvel star in the form of Evans. Leaked images from one of the film’s many sets, which circulated online earlier this year, fueled rumors that the Marvel Cinematic Universe (MCU) superstar would also be returning.
From what I read on the Internet doomsday trailer #1, it also appears that the film will be something of a direct sequel to Avengers: Endgame. This is the last time we saw Evans, who obviously was not part of doomsdayThe initial cast of 27 was revealed in March, under the name Rogers, so it will be fascinating to see how the films fit together.
As for the other teasers, the gossip columns are full of reports that the next one will focus on Chris Hemsworth’s Thor, before the third gives us our first official look at Robert Downey Jr.’s Doctor Doom. The fourth and final video is said to be doomsdayThe real trailer for – and if this is true, we might even see it go live after its premiere during Fire and ashesThis is the fourth week in theaters.
