Marvel’s High-Stakes Avengers: Endgame Rerelease Could Backfire

Marvel is taking a big swing: they’re cutting new scenes into Avengers: Endgame and sending it back to theaters this fall to tee up Avengers: Doomsday. It’s bold, it’s a little desperate, and it tells you exactly how nervous the studio is about getting people to care again.

What Marvel is actually doing

At CinemaCon 2026, Joe and Anthony Russo said a new theatrical cut of Avengers: Endgame is coming in September with added material. Joe Russo then got specific at the Sands Film Festival in St. Andrews, Scotland: the new footage is freshly shot story that plugs directly into Doomsday.

"We’re re-releasing the film with footage that is set in the Doomsday story that we have added to Avengers: Endgame."

"It’s a critical companion story and a setup for what you’re gonna watch in December when you see Avengers: Doomsday."

Translation: if you want to be fully prepped for Doomsday, Marvel would like you to buy another ticket to Endgame first. Endgame made $2.799 billion the first time around, so attaching fresh plot threads to the biggest hit in studio history is a guaranteed attention grab.

The Multiversal Saga problem (and the weird solution)

Doomsday and Avengers: Secret Wars are built to close out the Multiversal Saga, which Marvel has been trying to shape since 2021. In the seven years since Endgame, though, the brand’s shine has dulled: weaker box office, crankier reviews, too many core heroes MIA for too long, no obvious spine to the overarching story, and that creeping feeling that keeping up with the MCU is homework with less and less payoff.

Victor von Doom is supposed to be the big bad pulling this era together, and Marvel is rolling him out differently than it did Thanos. Instead of a slow-burn buildup across multiple films, Doom (played by Robert Downey Jr., yes, really) is set to make his first on-screen appearance in Doomsday itself. That’s a huge swing and a huge departure from the template that worked last time.

The stuff they’re sidelining isn’t nothing

Here’s what makes this strategy feel off: acting like the journey from 2021 to now can be mostly bypassed is a weird message to send when some of that run actually hit. Spider- Man: No Way Home did $1.9 billion in 2021 by cashing in on two decades of Spider-Man fandom across Sony’s movies. Shang-Chi and the Legend of the Ten Rings launched a legit crowd-pleaser of a new hero. Loki laid down the multiverse rules Doomsday will need to function. None of that is disposable. If you poured time and money into the Multiversal Saga, this new plan risks telling you that investment doesn’t really matter.

Turning Endgame into required reading (again)

Framing the Endgame re-release as essential pre-viewing leans into the exact critique that’s been dogging Marvel in the Disney+ era: you have to do homework to follow along. We already saw how asking casual moviegoers to watch entire seasons of shows to fully track movies like Doctor Strange in the Multiverse of Madness or Captain America: Brave New World turned people off. Now the assignment comes with a theatrical ticket price and a clock: see Endgame in September or risk missing setup for December.

You’re inviting a brutal comparison

Putting Endgame back on the big screen as the gateway to Doomsday sets up a tough side-by-side. Endgame is the payoff to 22 films of carefully paced storytelling, anchored by a decade of Robert Downey Jr. as Tony Stark. It’s the franchise at full power. Pointing audiences right back at that high-water mark is risky when the Multiversal Saga hasn’t matched that consistency. It could sharpen skepticism, not soothe it.

Messing with a three-hour machine

Endgame is long, but it’s engineered within an inch of its life to crest with Tony’s sacrifice. Dropping new Doomsday connective tissue into that structure could ding the pacing or undercut the ending. If the re-cut even slightly dents how people feel about Endgame, Marvel will have scuffed one of the last untouchable pieces of goodwill it has left.

What this move really says

• Marvel is effectively treating Doomsday as a direct sequel to Endgame, which implies the 2021–2026 slate (more than a dozen films plus a pile of Disney+ series) didn’t lock the central narrative into place the way they hoped.
• Audiences already started opting out with titles like Eternals and Ant-Man and the Wasp: Quantumania. Making a re-release the main bridge to the next tentpole risks telling loyal viewers their last five years of attention were optional.
• If entire chapters of the MCU become skippable by design, the whole interconnected-universe model that drove repeat theater trips and streaming subs for nearly two decades starts to wobble.

Dates to circle

The Endgame re-release with the new Doomsday footage hits theaters on September 25, 2026. Avengers: Doomsday opens December 18, 2026.

Are you buying a ticket to Endgame again in September because Joe Russo calls the new scenes critically important, or are you waiting to see if Doomsday stands on its own?
