If 2019's Avengers: Endgame marked the culmination of an era, Avengers: Doomsday (2026) is shaping up to be something closer to a reinvention. Marvel Studios has revealed little publicly, but industry conversations suggest the studio is treating the film as a defining chapter in the Marvel Cinematic Universe’s next evolution.
The project remains in post-production, with additional photography reportedly underway in the United Kingdom. On The Hot Mic, insider Jeff Sneider shared a cautiously optimistic progress report after checking with sources ahead of the show.
“It's still very much in post. Let me see if I have anything on that. I did check in before the show, just in case. I did get a little something. Avengers is in post, and they still have a lot of pick-ups to do, but the buzz is good. The buzz is good. You're going to like it,” Sneider said. “You're going to like the movie.”
Those pick-ups may be more than routine polishing. Observers believe Doomsday won’t simply continue existing threads but may overhaul the franchise’s internal order, steering the MCU toward what is coming to be known as the Mutant Saga.
That pivot is backed by familiar leadership. Joe and Anthony Russo, the architects behind Captain America: The Winter Soldier (2014), Captain America: Civil War (2016), Avengers: Infinity War (2018), and Avengers: Endgame (2019), have returned to direct. Their previous films defined Marvel’s most commercially dominant stretch, and their comeback signals a desire for cohesive, large-scale storytelling.
Teaser footage screened alongside Avatar: Fire and Ash (2025) points to an ensemble that spans generations. The preview reportedly included Chris Evans’ Steve Rogers, Chris Hemsworth’s Thor, several X-Men characters, Letitia Wright’s Shuri/Black Panther, and Ebon Moss-Bachrach’s Ben Grimm/Thing from The Fantastic Four: First Steps (2025). The appearance of Evans’ Captain America confirmed that the character remains active in this unfolding saga.
Then there’s Robert Downey Jr. In a twist few predicted, the actor who launched the MCU as Tony Stark is returning as Victor Von Doom. Doctor Doom was teased in the post-credits scene of The Fantastic Four: First Steps opposite Franklin Richards, setting the stage for a major confrontation.
How Doom functions within Doomsday remains a mystery. Rather than positioning him as a straightforward conqueror, speculation suggests a layered figure whose goals may intersect with preserving—or reshaping—the Multiverse. Some online theories even link his motivations to the ripple effects of Steve Rogers’ time-travel decision in Avengers: Endgame. Marvel has yet to clarify any of it.
Additional rumors only amplify the intrigue. One of the persistent claims is that the film could open with Tobey Maguire’s Spider-Man battling members of the X-Men, including Hugh Jackman’s Wolverine. While unconfirmed, the scenario highlights Marvel’s willingness to blur franchise lines in pursuit of event-level spectacle.
Still, not every insider is fully convinced. Daniel Richtman recently shared a tempered reaction, writing, “I have mixed feelings about the direction they’re taking with Avengers: Doomsday/Secret Wars. Some of it sounds super epic, but there are certain decisions I don’t want to spoil that I really don’t understand, and I think they’re going to make people REALLY angry,” the insider said.
Contrast that with reporting from Variety, which examined how Josh D'Amaro will approach his new role as Chief Executive Officer of The Walt Disney Company. According to the trade, internal sentiment appears strong.
“Executives are pleased with what they’ve seen for the December release, and rival studio heads privately predict Doomsday will be the year’s highest-grossing film,” the outlet notes.
Importantly, insiders suggest Disney does not view Doomsday as a single point of failure for the MCU—even after recent box office stumbles.
“Recent Marvel films Thunderbolts* and Captain America: Brave New World fell far short at the box office,” Variety writes. “Some pundits argue the future of the superhero franchise may ride on the hotly anticipated Avengers: Doomsday, although sources inside the company’s film division believe the health of the MCU does not hinge on an individual title.”
Narrative details remain scarce, but reports indicate Doom’s storyline could bring him into contact with the Fantastic Four, Thor, and Loki (Tom Hiddleston) amid escalating Multiversal incursions. If Doomsday and Secret Wars are indeed positioned as a “new beginning,” the MCU audiences know today may not emerge unchanged.
Before Doomsday arrives, Marvel and Sony will release Spider-Man: Brand New Day (2026), starring Tom Holland, in July. Described as a soft reset, that film—and the subsequent Avengers installments—may determine how far Marvel can push reinvention while maintaining continuity.
