AVENGERS: DOOMSDAY Teaser Leaks Online In HD As Rumors Of A FIFTH Trailer Surface

The best quality version of the first Avengers: Doomsday tease we’ve seen has shown up on social media, all while rumours swirl about plans to eventually release a fifth sneak peek.

The first of four Avengers: Doomsday teaser trailers leaked online this past Monday. As is often the case with these unexpected first looks, it appeared to have been recorded on a phone only capable of shooting 360p videos (don't even get us started on the Spider-Man: Brand New Day teaser...).

With Avatar: Fire and Ash now playing in theaters overseas, someone has finally captured our first look at Avengers: Doomsday on camera in 4K. It's still essentially a recording from the back row, but if you missed the previous leaks, you'll surely appreciate this one. 

Bizarrely, despite these teasers being theater-exclusives, Disney and Marvel Studios still haven't officially announced plans for them to play on the big screen in the coming weeks. 

The idea had been to get fans to buy tickets to see the new Avatar movie over four consecutive weekends, with a fresh teaser each time. Something could be coming tomorrow, but at this stage, it's hard to shake the feeling that Marvel Studios has made an early misstep with how it's choosing to promote Avengers: Doomsday.

The second teaser is expected to focus on Thor, with a third featuring Loki and the fourth set to finally introduce Robert Downey Jr.'s Doctor Doom. Based on how things have played out this week, expect those to leak each Monday at the soonest and by Wednesday at the latest.

There are also rumours swirling on social media today that a fifth teaser is coming, which will serve as a proper trailer for Avengers: Doomsday. That's the one expected to get an online release early next year (one leaker claims it will be a month after the fourth teaser, so roughly 8 weeks from now).

As we're sure you know by now, this first preview opens with former Captain America, Steve Rogers, riding a motorcycle and arriving at the house we last saw at the end of Avengers: Endgame (or one very similar to it).

Steve gets off his bike, picks up and looks at his old Captain America uniform inside, and instead decides to pick up his infant son. The brief teaser ends with "Steve Rogers Will Return In Avengers: Doomsday," along with a countdown to the movie's release this time next year.

Check out the first Avengers: Doomsday teaser trailer below. 

Avengers: Doomsday officially stars Chris Hemsworth, Anthony Mackie, Winston Duke, Tom Hiddleston, Sebastian Stan, Letitia Wright, Paul Rudd, and Robert Downey Jr. Wyatt Russell, Simu Liu, Tenoch Huerta Mejia, Florence Pugh, Danny Ramirez, David Harbour, Hannah John-Kamen, and Lewis Pullman all make their Avengers franchise debuts in the movie.

The Fantastic Four: First Steps leads Pedro Pascal, Vanessa Kirby, Ebon Moss-Bachrach, and Joseph Quinn join them, as do X-Men franchise stars Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, James Marsden, with Deadpool & Wolverine star Channing Tatum.

The Russo Brothers direct Avengers: Doomsday from a screenplay by Stephen McFeely, with whom they previously collaborated on the Avengers and Captain America franchises. Loki and Doctor Strange in the Multiverse of Madness's Michael Waldron is also working on the script.

Avengers: Doomsday is set to be released on December 18, 2026, with Avengers: Secret Wars scheduled to arrive on December 17, 2027.

So you're telling me there are potentially 4 more minutes of whatever this is? Surely they could just create a legit 2 and a half minute teaser.

kider2 - 12/17/2025, 6:17 PM
Ah you can see they didn't have a script.
If there was they could've just released a regular trailer.
That's why there are 5 of these trailers. It's all just random footage without dialogue with a slowed down version of the Avengers theme playing over it.
They'll figure out the dialogue in the last couple months or so and have the actors ADR.

You don't wanna mess it up when you can bring back more actors for cameos!

@kider2 - it’s a year out, the hype won’t start until July 31, 2026, right before Spider-man Brand New Day. Then late October/November no holding back, showing everything.

@kider2 - Almost NEVER get a full trailer until 6months prior to release, can't recall a single time there was a full trailer for a major film with a lot of CGI (or at all even sans CGI) a full one year in advance.

Teasers 12months in advance even is an exception not the norm.

Why doesn't Marvel just drop the HD trailer on Youtube? The trailer was always gonna get leaked, so why not just get ahead of the curve and generate some real hype

I just saw Avatar 3 and can confirm that the Avengers:Doomsday teaser with Steve Rogers was the only new trailer running before it.
At least in the theater i was in, in Germany. It is a discount theater which shows only 5 to 10 minutes of trailers, so other cinemas may show more trailers.
That being said it was very underwhelming.

Avatar 3 has a very slow 1st act, but gets going in act 2 and culminates in a giant fight in act 3.

Now i saw Avatar back on opening night and gave it a 7/10.
I didn't watch Avatar 2 to this day.
Avatar 3 gets a 8/10 from me.

It's basically the same as the first movie, storywise, but with much better fx.

@MarvelZombie616 - Avatar: Fire & Ash is much more similar to the Way of Water than to the 1st film (Way of Water was also entirely different story wise and visually compared to the first film).

I have the feeling you've not really seen any of them. Either that or you can't really remember what you really saw.

@MarvelZombie616 - I haven't seen the new one yet but basically one and two were the same: including the slow build up, dramatic finale. Sounds like for those who liked it will be not disappointed with the new one, while it will probably be same for those who didn't like the previous.

@MarvelZombie616 - saw it too as well. I always enjoy these movies and appreciate the effort in making them. And i have gone through all the mexican telenovela tropes to get the enjoyment out of these movies.

Having said that, it is a bummer that we didnt get any additional aspects in the mythos (maybe aside from spider). It is a rehash of the first 2 movies.

But overall, this has always been a technical acheivement and an audiovisual treat for me and i will always enjoy these

Honestly this is a pretty good marketing strategy when you think about it. Build up momentum with mini trailers that people leak onto the internet, and chatter about, keep doing it until even the radio and news start talking about it, and then drop the true first trailer. Bam! The world is talking about it, and counting down to the release.

It may seem odd to do what they're doing, but my guess is they're banking on the leaks as a type of gorilla marketing until they jump right into the main push.

@RedFury - it really does feel somewhat intentional imo otherwise whoever has leaked it will never be heard from again lol.

Even without an official release , wasn’t Doomsday trending at no 1 on Twitter for awhile?.

If so then it just shows that an intentional leak or not , the hype/interest for the film is there which is ultimately the purpose of any marketing material so mission accomplished imo.

Anyway , a Loki teaser would be interesting but I do hope we get a Doom one soon since that take & RDJ’s performance remain the biggest X factor of the film imo!!.

So for those folks who are saying "WTF are they doing by showing slow dramatic scenes with Steve and his kid?!?", I think that actually what Marvel/the Russos are doing is quite clever. Essentially what I think they are doing (time will see if I'm right) is setting up the emotional stakes for the main characters in this movie ahead of time. Think about it: We've now seen that Steve is living his best life ever with Peggy and a son, and has put the Cap mantle away for good. The Thor trailer will likely show Thor having fun being a father to Love and enjoying not having to be in epic battles every other week. The one with Loki will probably show Loki as holding the Multiverse together and looking down fondly on his friends living their own lives in their own realities. And the one with Doom (likely the last one) will probably show Doom holding his wife and son as they die in an incursion (probably ending with a big Doom "Noooooo!" scream or something like that.

The reason that I think that this is a clever move is because it helps to provide some context and backstory for each of these characters for those folks who have forgotten where Steve left things at the end of Endgame or didn't watch "Loki" S2 or "T:L&T", plus provide a brief background for Doom's motivation. It also sets up what the hero's stand to lose in "A:DD" if they have to give up everything to stop Doom.

Again, I might be spitballing here, but if the rest of the teasers work out the way I think then I think that it's pretty smart marketing on Marvel's part.

@StSteven - that's not even the real Loki so [frick] him
StSteven
StSteven - 12/18/2025, 4:35 PM
@Xplayr1X - Well sure, technically he's a variant, but our original Loki is dead, so he's the closest thing that we have now, and he did go through an emotional character arc (the original one did as well but not to the same degree as the variant Loki).

Either way, the 2 seasons of "Loki" DID establish emotional stakes for the current version of Loki, so I could see his teaser being him looking down on the realities where his friends (Mobius, et al) are living as well as Steve and Thor and then Doom's armored hand grabbing Loki by the throat and ripping him from his throne.

This would lead into the Doom teaser where we see Doom sitting on Loki's throne reliving what happened to his wife and son and then looking down at Steve's reality with Peggy and his son. And there you go. BAM! Sets you up just fine for the actual first trailer (whenever that comes out). I don't know if that's enough for everyone (assuming that it plays out anywhere close to how I envisioned it) to tide them over for a couple of months, but it's enough for me (for now).
