Don't Mourn Bucky Yet: Sebastian Stan Teases a Longer MCU Future After 'Avengers: Doomsday'

After his casting in The Batman 2 sparked fears that Bucky Barnes was being written out of the MCU in Avengers: Doomsday, Sebastian Stan used a Cannes interview to hint he hopes to keep playing the character for years to come. Marvel fans are dissecting every word—and daring to hope their Winter Soldier survives Doctor Doom.

Marvel fans bracing for the worst may have jumped the gun. After months of speculation that Bucky Barnes would be killed off in Avengers: Doomsday, Sebastian Stan has dropped a hint that his time in the Marvel Cinematic Universe is far from over—telling reporters at the Cannes Film Festival that he hopes to keep returning to the role for years to come.

Why Fans Feared the Worst for Bucky Barnes

The doom-and-gloom started the moment Sebastian Stan was announced for a major role in DC's The Batman Part II. With the actor seemingly committing to a second superhero franchise, fans did the math and assumed Marvel would clear the runway by giving Bucky Barnes a sendoff in the upcoming Avengers: Doomsday—likely at the hands of Robert Downey Jr.'s Doctor Doom.

It's a reasonable fear. Stan most recently led Thunderbolts as a more weathered, leadership-minded Bucky, and is confirmed to appear in Avengers: Doomsday. The idea of an actor juggling Marvel's Winter Soldier and DC's Gotham at the same time struck many as a setup for a tragic exit.

What Sebastian Stan Actually Said

Then came the interview that flipped the narrative. Speaking at Cannes (in comments shared by fans on X), Stan reflected on more than a decade of playing the character with the kind of warmth that doesn't sound like a goodbye:

"It's sort of like having a sibling you've never known you had, who you've spent 15 years with. There's been a comfort there returning every few years, which hopefully I'll keep doing."

That phrase—"which hopefully I'll keep doing"—is the one fans seized on. Stan has played Bucky Barnes since 2011's Captain America: The First Avenger, a run that genuinely does stretch back roughly 15 years, and the actor framed it as a relationship he wants to continue rather than close out.

The 'Avengers: Doomsday' Misdirection Game

Here's the catch, and seasoned Marvel watchers know it well: this wouldn't be the first time an MCU star has bent the truth to protect a secret. With Avengers: Doomsday guarding its plot tightly, it's entirely plausible Stan and his castmates are deliberately misdirecting fans about who lives and who dies. So far the film has revealed only a handful of teaser trailers publicly, plus a full trailer screened behind closed doors at CinemaCon—meaning almost nothing concrete is known about the story.

In other words, a comforting quote at Cannes is reassuring, but it is not a guarantee. If anything, the more an actor insists their character is safe, the more some fans brace for a gut-punch.

What This Means for Fans

For now, the takeaway is simple: the rumors of Bucky Barnes' death have been, at minimum, premature. As GamesRadar noted, Stan's affection for the role and his stated hope to keep returning suggest the Winter Soldier's story isn't necessarily ending with Avengers: Doomsday—and that a Batman role doesn't automatically mean a Marvel exit. Until Doomsday arrives and the secrecy lifts, fans are left doing what they do best: parsing every interview, holding onto hope, and refusing to mourn a fan-favorite hero one second sooner than they have to.
