Avengers Doomsday: the first trailer broken down shot by shot

On 20 July 2026, Marvel put online the first full trailer for Avengers: Doomsday, unveiled in the wake of San Diego Comic-Con. Within a few days it had passed 500 million views and broken Disney’s own record for the format.

This is not just a communications figure. It is a sign that audiences are waiting for this film as they have not waited for one since Endgame, and the trailer explains why: it brings together three cinematic universes that had never shared a single shot. Here is what it shows, sequence by sequence, and what can reasonably be drawn from it without extrapolating.

The opening shot: Xavier’s school abandoned

The trailer opens on Charles Xavier’s School for Gifted Youngsters — and the place is not in its usual state. The building looks poorly maintained, all but deserted. The sign welcoming new mutant pupils has fallen down.

Then we find Patrick Stewart at a window, looking at what resembles a tear in the sky. The shot says two things in a second: the mutant institution really does exist in this story, and it has already taken a hit.

That choice of opening is telling. An Avengers film that begins in an X-Men location announces that the centre of gravity has shifted. We no longer start from the Tower or the Sanctum: we start from an empty school.

The composition of the shot is worth pausing on. A school built to take in children, filmed deserted, produces an unease that ten explosion shots would never achieve. It is a visual grammar borrowed from unsettling cinema rather than from the superhero film, and it immediately places the viewer in a different register from the one the franchise had accustomed them to.

The Fox X-Men are back, for good

This is the film’s main selling point and the trailer makes no secret of it. The actors from the Fox-era X-Men are reprising their roles: Patrick Stewart as Charles Xavier, Ian McKellen as Magneto, James Marsden as Cyclops, Kelsey Grammer as Beast, Rebecca Romijn as Mystique, Alan Cumming as Nightcrawler.

To put the event in context: these performers belong to a franchise that started in 2000, in a separate cinematic universe, with its own rules and its own continuity. Seeing them share the screen with the Avengers is what comics call a crossover — an exercise the medium has practised for a very long time, as we showed in our round-up of the wildest crossovers.

The pairing of the web-slinger and the mutants also has a long history on the page, one we traced in our article on their links through the comics. What cinema is attempting here, the pages have been doing for decades.

Avengers versus X-Men: the battle at the mansion

A large part of the trailer is taken up by a confrontation between the Avengers and the X-Men, inside the grounds of the mansion. This is no skirmish: the shots show a pitched battle, with heroes from both camps set against one another.

Comics readers will recognise a classic motif. Setting the two teams against each other is a recurring device on the page, usually triggered by outside manipulation or by a fundamental disagreement about the place of mutants. The film appears to take up that pattern rather than offering an immediate alliance.

One casting detail confirms the scale: Simu Liu faces Channing Tatum in the role of Gambit. The duel brings together a character introduced recently on the Marvel side and an X-Men figure fans have been waiting to see on screen for a very long time.

The choice of this face-off is probably no accident. These are two hand-to-hand fighters, with no armour and no flight, whose powers run through an energy-charged object. Where most of the film’s clashes will pit powers that are hard to frame against each other, this one stays legible and choreographable — exactly the kind of sequence a first trailer pushes forward to reassure viewers about the staging.

Thor, the axe, and Doom’s hand

The most discussed shot may well be the simplest. Thor comes down on a hooded figure, his axe swung at full force. The blade is stopped dead by Doctor Doom’s raised hand, and the two forces stay locked in tension, motionless.

In a single shot, the film establishes the level of threat. Doom does not dodge, does not shelter behind a visible force field: he catches. It is a statement of intent about what this character represents against an entire team.

For anyone discovering the character through the films, it is worth knowing that he carries an old feud with the Spider-Man universe. We told that rivalry in our article on the duel between Spider-Man and Doctor Doom: two intellects, two methods, and a mutual contempt that has never faltered.

‘Hey pal’: the return of Steve Rogers

The trailer saves its strongest card for last. Thor hears a voice behind him — two words, ‘hey pal’. He turns, disbelieving, and holds out his hand: Mjolnir leaves his palm and flies towards someone else. Steve Rogers steps into the light.

This is Chris Evans returning to the role for the first time since 2019. The device is clever: rather than showing the character, the film shows the hammer that points to him. Only someone worthy can lift it, and the image says so without a line of dialogue.

The audience reaction to that shot explains a good share of the 500 million views. After several years in which the universe was looking for a new centre, this return acts as a signal: the film is happy to replay the emotion of the great team-ups that came before.

The Sentinels: Doom’s army

The other major reveal came with the Comic-Con presentation: Doom is raising an army of Sentinels to take on the Avengers, the Fantastic Four and the X-Men all at once.

In the comics, the Sentinels are giant robots designed to hunt down and eliminate mutants. Handing them to Doom changes their nature: from a tool of targeted persecution, they become an instrument of general domination. The film takes an X-Men iconography and widens it to the whole universe.

Spider-Man readers will see an immediate echo. The web-slinger has long faced hunting machines of his own, a lineage we set out in our article on the Spider-Slayers. Anti-mutant robots on one side, anti-spider robots on the other: the same idea of industrial hunting, applied to two different minorities.

The Fantastic Four in the equation

The third group present is the Fantastic Four, with Pedro Pascal as Reed Richards, Vanessa Kirby as the Invisible Woman, Joseph Quinn as the Human Torch and Ebon Moss-Bachrach as the Thing.

Their presence is logical and even necessary: Doom is historically their enemy, not the Avengers’. The film therefore imports one team’s antagonist to make him the threat to all the others, which implies that the relationship between Reed Richards and Victor Von Doom takes up a place in the story.

Here again, the pages are ahead of the screen. The web-slinger’s dealings with that team are long-standing and documented, as shown by the Civil War episode, where the alliances between groups were reshaped for good.

And where does Spider-Man fit in?

A fair question on this site, and an honest answer: the trailer does not show him. The detailed write-ups published after the release list the heroes on screen, and he is not among them.

That settles nothing — a trailer never shows everything, and studios deliberately hold certain appearances back for the cinema. But as things stand, everything circulating about his involvement is inference, not footage.

We handled that question separately, with what is established and what is not, in our article on Spider-Man’s role against Doctor Doom. And on the recurring rumour about the three actors reuniting, we sorted out what is actually known from what is assumed.

Why this crossover took twenty-five years to arrive

The detail many younger viewers miss: if the X-Men and the Fantastic Four were absent from the Avengers for so long, it was not an artistic choice. It was a question of rights.

These characters have belonged to the same comics since the 1960s, but their film adaptation rights had been sold to another studio in the 1990s, at a time when Marvel was in poor financial health. The result: two separate catalogues, two continuities, and a legal impossibility of ever having them cross paths.

Disney’s purchase of the studio that held them, completed in 2019, removed the obstacle. But buying rights is not enough to write a film: the Fantastic Four had to be introduced, the mutants reintroduced, and a narrative mechanism found that could justify characters from incompatible continuities sharing the screen.

That is precisely what the multiverse is for. Rather than pretending the older films never existed, the device folds them in as neighbouring universes. The trailer draws its strongest argument from that: these actors are not replaying their roles, they are continuing them.

A record that says something

More than 500 million views in a few days, and a record broken across the whole Disney group. The figure deserves to be read with caution — view counters add up very different platforms and viewing durations — but the order of magnitude remains significant.

Above all it says one thing: after several years in which the universe’s productions met uneven receptions, a team-up on this scale still mobilises people massively. The curiosity is not only about the plot, but about the very possibility of seeing these characters share a shot.

For comparison, the attention paid to the franchise’s releases remains far above that of most other licences, as we measured when looking at the path of the cinematic universe since its origins. A promotional start like that mechanically places the film among the events of the end of the year.

What the trailer does not show

A serious breakdown must also say what is missing. The trailer does not explain how the universes come into contact, does not spell out Doom’s motives beyond his warning about the collapse of the multiverse, and gives away nothing of the ending.

Several major heroes announced in the cast do not appear in the edit, which is normal at this stage. Concluding that they are absent from the film would be a method error: a trailer is a promotional object, not a table of contents.

Caution too on the multiverse mechanics. The vocabulary used refers to ideas already established on screen, which we explained in plain terms in our guide to the Marvel multiverse and in our look back at No Way Home, the film that opened the breach.

How to watch a trailer without being taken in

A word on method, because the period ahead is going to generate a lot of noise. A trailer is cut to sell, not to inform. Shots are reordered, sometimes retouched, and some never appear in the finished film.

Three precautions apply to this one as to those that follow. First, the order of the shots is not the order of the story: two images side by side do not necessarily follow one another on screen. Second, a line heard over a shot may have been spoken in another scene, since the sound edit is free. Finally, a character’s absence proves nothing, and their presence in a single image says nothing about the size of their role.

These reservations are not theoretical: the franchise’s previous team-ups used altered shots in their marketing, including digitally removing a character to protect a surprise. It is therefore reasonable to treat the images as clues, not as established facts.

The simplest rule remains the best: separate what is shown from what is inferred. Everything this article states comes from the edit that was released or from the official Comic-Con presentation. The rest, we flag as uncertain.

Release date and what comes next

Avengers: Doomsday is released in cinemas on 18 December 2026, directed by the Russo brothers, already responsible for the franchise’s two previous big team-ups.

The film is not an end in itself: it opens onto a second instalment, whose implications we examined in our article on Secret Wars. The two-part structure recalls the one that worked before, with a first part setting things up and a second resolving them.

To prepare for the screening, the overview of the films and the universes puts the continuities back in order — and the question of which Spider-Man belongs to which universe also remains open.

What to take away

This trailer does exactly what you expect of a first trailer: it sets up the threat, shows the scale of the team-up, and saves an emotional beat for the end. Xavier’s empty school, Doom’s hand stopping an axe, and two words spoken off screen.

Four and a half months still separate audiences from the cinema, and more trailers should be expected between now and December. This one mainly served to answer the only question that mattered: yes, the Fox X-Men really are there, and yes, Steve Rogers is back.

In the meantime, our Spider-Man figures and posters cover the universe in question well, while the decorations, the T-shirts and the Spider-Man masks complete the waiting kit. For the character we care about here, the full profile of Peter Parker remains the best way in.
