Avengers: Doomsday unveils exciting new trailer during CinemaCon

During CinemaCon on April 16, 2026 in Las Vegas, Marvel Studios presented new footage from the latest addition to the Marvel Cinematic Universe, Avengers: Doomsday. The trailer, which reportedly sparked huge excitement, included major reveals, including a first look at Robert Downey Jr. as the villain Doctor Doom.

Reactions to the trailer

It has emerged that individuals who tried to film the trailer were immediately removed by security. This shows just how secretive and valuable the reveal of the footage was for Marvel.

The trailer opened with the words: "Something's coming. Something we may not be able to deter" and showed scenes of the destroyed X-Mansion. This imagery sets a dark and tense tone for the upcoming film. Alongside Doctor Doom, Thor was also shown, commenting on his battles with countless enemies. That surprised fans, given his previous adventures in other Marvel films. The trailer strongly hints at future conflicts and the involvement of familiar characters.

Key actors and characters

Robert Downey Jr., best known for his role as Tony Stark/Iron Man, is now taking on the role of Doctor Doom. There has been speculation that this version of Doom could be a variant of Tony from another multiverse. However, based on the footage shown, that does not appear to be the case. Thor and Steve Rogers also returned in the trailer, strengthening the connection to the wider Marvel universe.

The next chapter in the Marvel saga

Marvel Studios president Kevin Feige has confirmed that Avengers: Doomsday will pick up directly after Avengers: Endgame, suggesting the story will have major consequences for the characters and fans. The film is scheduled to release on December 18, 2026. Before that, Spider-Man: Brand New Day arrives on July 31, though it is still unclear whether Spider-Man himself will appear in Doomsday.

With Avengers: Doomsday on the horizon, fans are eagerly awaiting more reveals and the impact this film will have on the Marvel universe.
