Copyright takedowns are sweeping across social media after what appears to be a leaked version of Marvel’s first Avengers: Doomsday trailer surfaced online. The clip was reportedly uploaded in multiple places and was easy to find at first. But by the next day, many posts were replaced with copyright notices, and the video became difficult to locate.
The quick wave of removals is not unusual when major studios spot unauthorized uploads. It is also one of the strongest signals that a clip is real (or close enough to cause legal concern), even when the studio does not publicly confirm anything.
Source note: This article is a summary and explainer based on reporting by IGN.
What happened: uploads appeared, then disappeared
According to IGN, the alleged trailer began circulating online and was widely shared across social platforms. Soon after, copyright takedowns started targeting reposts of the file. Reports indicate that copies were removed or blocked on platforms including X and Reddit, and that the original video was not available on YouTube by the time takedowns spread.
That sequence is common in trailer leaks:
- A clip appears and spreads fast through reposts.
- Fans mirror it across accounts and platforms.
- Copyright claims begin, and the most visible uploads vanish.
- Discussion continues even after the clip is gone.
If you are a creator covering entertainment news, this is the moment when you can publish an update without embedding the footage. You can report the basic facts (takedowns, fan reaction, context from prior reporting) while avoiding sharing copyrighted material.
Spoiler note: what the leaked clip reportedly shows
Warning: The next section discusses details described in coverage of the leaked footage. If you want to stay fully unspoiled, skip ahead to the “What this means” section.
IGN reports that the clip includes a blurry glimpse of a returning character who has not appeared since the last Avengers film. The report identifies the character as Steve Rogers, the original Captain America, played by Chris Evans.
As described, the footage allegedly opens with a figure arriving on a motorbike at a familiar-looking 1950s house that fans may recognize from the closing of Avengers: Endgame. Inside, the person is revealed to be Steve Rogers, shown putting away his Captain America uniform and holding a baby. The clip reportedly ends with text suggesting Rogers will return in Avengers: Doomsday.
Marvel has not formally announced Steve Rogers as part of the film’s story. For now, this remains unconfirmed and tied to a trailer that was not officially released.
Why fans think it could be real
Even before this alleged trailer surfaced, speculation about Steve Rogers had been building. IGN points to earlier reports that suggested a similar house set may have been constructed during filming. That kind of detail can add fuel to theories, especially when combined with the studio’s silence.
IGN also notes that fans have been analyzing recent public photos of Chris Evans and debating whether he appears to be in “Captain America shape.” That type of fan detective work is a regular part of big franchise coverage now, particularly when Marvel projects are in production and secrecy is tight.
On top of that, takedowns themselves often become part of the story. When a company acts quickly to remove a video, many fans read it as an indirect acknowledgment that the footage is legitimate or uses protected material.
How Steve Rogers returning could fit the story
From a story perspective, IGN argues there are ways a Steve Rogers return could make sense, even after Endgame. Rogers was last seen living a quiet life in the 1950s with Peggy Carter after returning the Infinity Stones to their proper places in the timeline.
Bringing him back could be controversial, because many fans view that ending as a clean, emotional wrap-up. Still, there is room inside the Marvel timeline for more story threads, especially if Avengers: Doomsday is positioned as a major finale within the Multiverse Saga.
IGN also highlights a long-running MCU logic question: under the rules the films described, Steve Rogers should have created a branch reality by staying in the past. Yet he appears in the main timeline later to pass the shield. Some fans have wanted a clearer explanation for years.
That gap creates a narrative opening. A future film could explain how Rogers got back to the primary MCU reality, or how the multiverse story forces him into action again.
What Marvel and Chris Evans have (and have not) said
At the time of IGN’s reporting, Marvel had not officially confirmed Steve Rogers as part of Avengers: Doomsday. IGN also references comments Evans previously gave to ScreenRant that did not directly confirm or deny involvement. In those remarks, he spoke about staying in touch with the cast and described feeling “sad to be away,” while also suggesting the project would be “incredible.”
That kind of answer keeps the door open. It also keeps fans guessing, which is not always an accident in franchise marketing.
What copyright takedowns mean (and what they do not)
Copyright takedowns usually mean one simple thing: a rights holder believes a post contains protected material. It does not always mean a studio has confirmed the plot, approved the footage, or plans to release it soon. It can also happen when a clip uses copyrighted video, audio, or even a watermark from a protected source.
Still, takedowns do show that the company is watching closely. For big releases, studios often use automated systems plus manual reporting to remove unauthorized footage quickly.
If you run a website or social account, it is safer to:
- Report on the news event (leak, takedowns, official silence, fan response).
- Avoid embedding the clip or rehosting it.
- Use your own images (or licensed images) and keep references descriptive.
- Link to reputable coverage instead of linking to pirate uploads.
A clip claimed to be the first Avengers: Doomsday trailer briefly spread online before being hit by a wave of copyright takedowns. The footage, as described by IGN, appears to tease a possible return of Steve Rogers, which would be a major story move if true. For now, Marvel has not made an official announcement, so fans are left reading signals from set rumors, past comments, and the speed of takedowns.
