Marvel Fans Lose It Over Leaked ‘Avengers: Doomsday’ Video: Is Wolverine Coming?

A short, grainy TikTok video, allegedly leaked from the London set of Avengers: Doomsday, has sent the internet into overdrive. Originally uploaded by a user going by the handle @TheyNeverSawItComing, the now-deleted clip gave viewers what appeared to be a behind-the-scenes look at one of Marvel’s most secretive upcoming blockbusters, directed by the Russo Brothers.

Though the original post vanished almost as quickly as it appeared, it’s already made its rounds across platforms like Instagram and X (formerly Twitter), igniting a storm of speculation, frame-by-frame breakdowns, and more than a few conspiracy theories.

Madripoor Makes a Comeback?

The most intriguing detail from the leaked footage? A set that fans believe strongly resembles Madripoor, the lawless Southeast Asian island first seen in The Falcon and the Winter Soldier. The fictional city, dripping in noir aesthetics and criminal intrigue, has deep roots in Marvel Comics—particularly the X-Men storyline and Wolverine’s own history.

“If Madripoor is in this movie, does that mean we’re finally getting closure on Sharon Carter and the Power Broker? Or… Wolverine?” one fan speculated on X. The comments have been flooded with questions about the Power Broker’s arc, mutant cameos, and whether this is the official start of the X-Men’s entrance into the MCU.

Given Madripoor’s connection to Marvel’s mutant lore, its appearance could mark a pivotal moment in expanding the MCU beyond its current Avengers-centric lineup.

Is Robert Downey Jr. Returning… as Doctor Doom?

As if that wasn’t enough fuel for fan theories, rumors swirling alongside the leak have hinted at a shocking casting twist—Robert Downey Jr., the man who defined the MCU as Tony Stark/Iron Man, might be back… but not as Iron Man.

Whispers in insider circles (and a few cryptic scoops from well-known leakers) suggest that Downey Jr. could be stepping into a completely different role: Doctor Doom. While nothing has been confirmed, the internet has been ablaze with reactions ranging from awe to disbelief. Could Marvel really bring back its biggest star in a villainous avatar?

What We Know About Avengers: Doomsday

Details about Avengers: Doomsday have been kept tightly under wraps, but it’s already positioned as a major linchpin in Phase 6 of the MCU. With the Russo Brothers at the helm and rumors of a multiverse-collapsing plot, the film is expected to go even bigger than Endgame.

The film was already teased as a game-changer, but the leaked set video—if legitimate—may have given fans their first glimpse into just how massive the stakes will be. Between a possible Madripoor setting, mutant hints, and Robert Downey Jr. comeback rumors, Avengers: Doomsday is already living up to its name.
