Avengers Doomsday Rocks CinemaCon With First Doom Footage
April 16, 2026, 4: 42 PM ET — avengers doomsday jolted CinemaCon in Las Vegas on Thursday as Marvel Studios unveiled the first full-length trailer for the film. The footage gave the crowd its first extensive look at Robert Downey Jr. as Doctor Doom and confirmed that the movie is headed toward a multiverse collision. Marvel executives framed avengers doomsday as a direct continuation of the story that began with Avengers: Endgame.
First look at Doom sets the tone
Marvel Studios chief Kevin Feige took the stage to close Disney’s presentation and said avengers doomsday picks up where Avengers: Endgame left off. He also said he was excited to introduce the Avengers to the X-Men.
The trailer opens on Downey Jr. in a green hood and metal face as Doctor Doom prepares to invade the multiverse. From there, the footage turns into a rapid series of confrontations: Thor faces Doom, Professor Xavier is shown looking out from the X-Mansion, and the X-Men, Fantastic Four, Thunderbolts, and Avengers all appear to be pulled into the same conflict.
Joe Russo described Doom as more than a standard villain, calling him one of Marvel’s most complex characters and saying he is always three moves ahead. The trailer presentation also made clear that avengers doomsday is being positioned as one of Marvel’s biggest ensemble films yet.
Chris Evans returns, and the crowd reacts
The biggest reaction came when Chris Evans appeared as Steve Rogers and picked up Thor’s hammer, surprising Chris Hemsworth in the footage and on stage. Hemsworth’s Thor says the heroes will need a miracle, and Evans then added his own blunt take on Doom: “This guy — I don’t like it. ”
Downey Jr. also took the stage after being introduced to the tune of “Sympathy for the Devil, ” telling the audience that he could not have imagined reuniting with the team as a new character. That moment underscored how central his return is to the push around avengers doomsday.
The trailer also included battles involving Gambit and Shang-Chi, a Mystique-to-Yelena transformation, and a tense meeting between the Fantastic Four and the New Avengers lineup. These scenes suggested a film built around collisions between teams rather than a single linear showdown.
Why the film matters now
Marvel has already used a series of brief teasers to build interest, and those clips reportedly drew 1 billion views online combined. This first full trailer is the clearest sign yet of the scale Marvel is aiming for with avengers doomsday.
The film is set to open in theaters on Dec. 18, and the studio is clearly counting on the return of familiar heroes, the arrival of the X-Men, and Downey Jr. ’s Doom reveal to drive the conversation through the rest of the year.
What happens next for Avengers Doomsday
For now, the major plot points remain tightly guarded, but the CinemaCon footage made one thing plain: avengers doomsday is being built as a massive crossover event with Doctor Doom at the center. With the release date approaching and more footage likely to follow, the next wave of attention will focus on how Marvel expands that multiverse clash without giving away the ending too soon.
