Marvel fans are buzzing over alleged set footage from Avengers: Doomsday that appears to show the X-Mansion under siege, fueling speculation that the film will open with a brutal defeat for the classic X-Men cast. Following the shocking announcement that actors from the early 2000s X-Men franchise—including Patrick Stewart, Ian McKellen, and Kelsey Grammer—will join Robert Downey Jr.’s Victor von Doom in the May 2026 sequel, this latest leak provides a potential glimpse into how these multiversal heavyweights will collide.
Is the X-Mansion the New Infinity War Opening?
The speculation stems from drone footage uploaded to YouTube, reportedly capturing the set of the upcoming blockbuster. The visuals depict the iconic Xavier Institute for Higher Learning courtyard scarred by craters and explosions, shielded by a perimeter of shipping containers—a classic setup for heavy CGI integration. The scale of the destruction has led many to compare the scene to the opening of Avengers: Infinity War, where Thanos established his dominance by dismantling the Hulk.
Fans Predict a Brutal Introduction for Dr. Doom
The theory gaining the most traction is that the X-Men’s demise at the mansion will serve as the movie’s high-stakes cold open. On the Marvel spoilers subreddit, fans have suggested that having Dr. Doom single-handedly decimate an established superhero team would be the ultimate way to cement his status as the MCU’s most formidable threat.
“It’d be badass if the intro of this movie was Dr. Doom beating the X-Men’s ass just like the first Ultimate Alliance game,” noted user BigPaleontologist520. Others pointed out a practical benefit to this narrative choice: “Getting the geriatric cast out of the movie early would make it less jarring to see them as they have aged,” added user SpiffySpacemanSpiff. By positioning the X-Men as early casualties, Marvel could avoid the common critique that legacy cameos are merely nostalgic fan service, instead using them to raise the stakes for the Avengers.
Separating Rumors from Reality
While the imagery is compelling, it remains unconfirmed whether this sequence is actually the film’s opening or a later climax involving multiverse incursions. Skeptics have also been quick to point out that the X-Mansion has historically been a frequent target for destruction in the comic books. As one Reddit user aptly quipped, “I wouldn’t read too much into it; the school blows up every Monday, Wednesday, and Friday.”
With the multiverse now a core component of the MCU, the writers have immense flexibility to justify any scenario. Whether the mansion footage represents a tragic beginning for the X-Men or a recurring trope of their franchise, the leak has successfully heightened anticipation for how Avengers: Doomsday will integrate these iconic characters into its sprawling narrative.
