Marvel Studios has officially delayed the release of its next two Avengers blockbusters. Avengers: Doomsday, initially slated for May 1, 2026, will now premiere on December 18, 2026. Avengers: Secret Wars has been pushed back to December 2027.
The news comes as the studio finalizes its creative direction, with the Russo brothers returning to direct both films. In a significant twist, Robert Downey Jr. will not reprise his iconic role as Iron Man—instead, he’s set to portray the villainous Doctor Doom, marking a dramatic shift in the Marvel Cinematic Universe.
The updated timeline gives Marvel more breathing room to build toward the climactic showdown fans eagerly anticipate.
