Marvel Studios has been building Avengers: Doomsday as a massive multiverse event, packed with legacy heroes and timeline chaos. But one newly revealed production detail suggests the studio is also leaning on nostalgia to make that crossover feel more real.

Kevin Feige recently confirmed that Avengers: Doomsday is using physical sets from the original X-Men films. The move not only saves time in production but also helps preserve the look and feel of the Fox-era mutant universe as it merges into the MCU.

“No spoilers but there might some sets that you recognise from those original films and being on those sets 26 years later with my 12 year old son was pretty emotional,” he said during an interview with Fandango at CinemaCon 2026. Feige reflected on the emotional impact of revisiting those sets.

The reveal suggests Marvel is doing more than bringing back familiar faces. By reusing pieces of the original X-Men world, the studio is making this crossover feel like a true continuation of that legacy.

That fits with Marvel’s wider multiverse strategy in Avengers: Doomsday. Instead of simply dropping the X-Men into the MCU, Marvel appears to be preserving the world they came from.

That nostalgic decision becomes even more interesting when viewed through the film’s larger MCU timeline setup.

Marvel Reveals How Avengers: Doomsday Expands the MCU Timeline

Kevin Feige has made it clear that Avengers: Doomsday will move the MCU timeline forward rather than revisit the past. Set after the events of Avengers: Endgame, the film is expected to explore the fallout of a fractured Avengers team while pushing the multiverse storyline into even more dangerous territory.

“Avengers: Doomsday picks up where Endgame left off,” Feige said at CinemaCon, confirming that the story remains anchored in the MCU’s present timeline.

At the same time, it expands outward by pulling in elements from earlier Marvel franchises, opening the door for realities from different eras to collide.

Kevin Feige also revealed that the movie will finally unite the Avengers and the X-Men on screen, describing it as the crossover fans have waited years to see. That crossover points to the Fox mutant universe merging with Earth-616 as multiversal incursions begin tearing down the barriers between realities.

At the center of that collapse is Doctor Doom, whose rise appears to trigger the next major crisis in the MCU. By blending legacy timelines with present-day MCU events, Avengers: Doomsday is shaping up to be the bridge between Marvel’s cinematic past and its multiversal future.

Kevin Feige’s reveal shows that Avengers: Doomsday is not just borrowing characters from Marvel’s past; it is bringing back the worlds they came from.
