Avengers Doomsday Runtime Revealed: Russo Brothers Tease Epic Lengths for MCU’s Next Blockbusters

The Russo Brothers have pulled back the curtain on the much-anticipated Avengers Doomsday runtime, igniting excitement among Marvel fans worldwide. In a March 5, 2025, interview with Collider, Joe and Anthony Russo disclosed that Avengers: Doomsday is eyeing a 2.5-hour duration, while its sequel, Avengers: Secret Wars, could stretch to an epic 3 hours.

As the duo gears up to helm these Multiverse Saga capstones—set to hit theaters in May 2026 and May 2027, respectively—these runtime hints suggest a grand scale rivaling their past hits like Avengers: Endgame. With filming slated to begin in April 2025, here’s everything we’ve uncovered about these colossal runtimes and what they mean for the MCU’s future.

What Did the Russo Brothers Reveal About the Runtimes?

Joe Russo didn’t mince words when asked about the runtimes, stating, "If I were a betting man, I would say the first one is two and a half, and the second one’s three hours." This aligns with their signature style—Infinity War clocked in at 149 minutes (just over 2.5 hours), and Endgame soared to 181 minutes (just over 3 hours).

The announcement, made while promoting The Electric State, has fueled X posts from users like @MCU_Direct and @cosmic_marvel, amplifying fan anticipation. These estimates hint at the massive storytelling canvas the Russos are preparing for Doomsday and Secret Wars.

How Do These Runtimes Stack Up Against Previous Avengers Films?

The Russo Brothers have a history of crafting lengthy MCU epics, and these new films seem to follow suit. Infinity War’s 2.5-hour runtime juggled a galaxy-spanning cast, while Endgame’s 3-hour saga delivered a satisfying Infinity Saga finale.

If Doomsday lands at 2.5 hours and Secret Wars hits 3 hours, they’ll mirror this precedent, with Secret Wars potentially tying Endgame as one of the MCU’s longest entries. This consistency underscores their knack for balancing spectacle and substance across extended runtimes.

Why Are These Runtimes Crucial for the Multiverse Saga?

With the Multiverse Saga introducing a dizzying array of characters and timelines, these runtimes signal an ambitious wrap-up. Doomsday, releasing May 1, 2026, will spotlight Robert Downey Jr.’s Doctor Doom and the Fantastic Four’s MCU debut, requiring ample time to set the stakes.

Secret Wars, arriving May 7, 2027, promises an even grander clash, adapting the iconic comic event. Joe Russo told TechRadar they’re pulling from both the original and Hickman Secret Wars runs, suggesting a dense narrative that demands those extra minutes.

Could the Runtimes Still Change Before Release?

While the Russo Brothers sound confident, these figures aren’t final. Joe’s “betting man” phrasing leaves wiggle room, and with filming starting in April 2025 in London, edits could shift the totals. Endgame famously evolved in post-production, and X speculation from users like @screentime suggests Secret Wars might even exceed 3 hours to fit its scope.

The brothers’ plan to shoot on soundstages, as noted in Collider, aims to keep spoilers at bay, but runtime tweaks could still emerge as production progresses.

What Else Did the Russo Brothers Hint About the Films?

The Russos aren’t just banking on runtimes to impress—they’re aiming to top themselves. Joe told GamesRadar+ they want to “beat those younger versions of ourselves,” while Anthony called the story “radical” and “challenging.”

With Downey Jr.’s Doom, a stacked cast including Pedro Pascal and possibly Chris Evans, and a multiversal showdown, these films promise to push boundaries. Their six-month shoot per film, confirmed to Collider, reflects the scale they’re tackling.

How Are Fans Responding to the Runtime News?

Fan reactions on X have been electric, with posts from @SpiderMan_Newz and @CultureCrave highlighting the hype. Some cheer the extended runtimes as a treat for MCU diehards, while others debate if 3 hours for Secret Wars can avoid pacing pitfalls.

The consensus? The Russos’ track record—delivering Infinity War and Endgame as top-grossing masterpieces—gives them leeway to go big. Fans trust they’ll make every minute count.

Some Closing Thoughts:

The Avengers: Doomsday runtime of 2.5 hours and Secret Wars’ potential 3-hour sprawl confirm the Russo Brothers are doubling down on epic storytelling for the MCU’s Multiverse Saga climax. As they prepare to outdo Infinity War and Endgame, these films could redefine superhero cinema once more. With production looming and fan excitement at fever pitch, May 2026 can’t come soon enough.

The countdown is on—will these runtimes deliver the ultimate Marvel payoff? Only time will tell.
