The avengers doomsday trailer took center stage at CinemaCon on April 16, 2026 ET, as Marvel Studios unveiled the first full-length look at the film in Las Vegas. Robert Downey Jr. appeared onstage with the cast as the footage introduced Doctor Doom and set up a collision with Thor, the X-Men, and other major Marvel figures. The presentation closed Disney’s CinemaCon session and gave theater owners their clearest look yet at the movie set for Dec. 18.
Doctor Doom Takes the Spotlight
The avengers doomsday trailer opened with Downey Jr. in a green hood and metal face as Doctor Doom prepares to invade the multiverse. Kevin Feige said the film “picks up where Avengers: Endgame left off” and noted his excitement about bringing the Avengers and the X-Men together.
Joe Russo described Doom as “not simply a villain, ” but “one of the most complex Marvel characters, ” adding that he is “always three moves ahead. ” The footage then moved fast, showing crossovers and clashes that place Doom at the center of the conflict.
Thor, Cap, and the Hammer Moment
One of the biggest reactions came when Chris Hemsworth’s Thor warned fellow heroes that they would need “a miracle” if they were going to face Doom. The avengers doomsday trailer then cut to the moment Chris Evans’ Steve Rogers returns and grabs Thor’s hammer, leaving Hemsworth’s character stunned and saying, “It’s not possible. ” Evans later joked onstage, “This guy — I don’t like it. ”
The trailer also showed Thor and Doom facing off, with Doom catching Mjolnir barehanded. Another shot placed Professor X at his X-Mansion as trouble flashes outside, while other scenes included Gambit and Shang-Chi in battle and Mystique transforming into Yelena Belova.
What the Footage Says About the Story
The avengers doomsday trailer suggests a huge collision of Marvel teams, with Earth’s Mightiest Heroes joining forces with the X-Men, Fantastic Four, and Thunderbolts. The footage also showed the Fantastic Four meeting the New Avengers, a group made up of Bucky Barnes, Yelena Belova, Sentry, Ghost, Red Guardian, and U. S. Agent.
Marvel has kept the plot under wraps, but the trailer made clear that Doctor Doom is the central threat pulling every faction into the same fight. The presentation marked the first extensive footage after brief teasers released in late 2025 and earlier this year.
Immediate Reactions at CinemaCon
Downey Jr. took the stage to “Sympathy for the Devil” and told the crowd, “I couldn’t have imagined reuniting with this amazing team — let alone as a new character. ” The avengers doomsday trailer was shown twice for the packed CinemaCon audience, underscoring how strongly the footage landed with theater owners.
Feige framed the film as a major continuation point for the Marvel story, while the Russos return to direct from a script by Michael Waldron and Stephen McFeely. The film is also being positioned as a major box-office contender heading into 2026.
What Comes Next
With release still set for Dec. 18, the avengers doomsday trailer has now shifted the focus from teasing to anticipation. The next big question is how Marvel will build on this first full look before audiences see the final film in theaters.
For now, the avengers doomsday trailer has done what it was meant to do: put Doctor Doom at the center, reunite familiar heroes, and make the road to Dec. 18 feel much shorter.
