Excitement is building for Avengers: Doomsday, and recent comments have brought intense speculation about character fates, particularly as Sebastian Stan Avengers Doomsday rumors circulate. The upcoming blockbuster, set for late 2026, is drawing attention not just for its all-star cast but also for the hints of significant losses within the Marvel Cinematic Universe (MCU).
Anticipation and Hints at High Stakes
Avengers: Doomsday is positioned as a monumental crossover, uniting the Avengers, New Avengers, Fantastic Four, and X-Men, creating a cinematic event with massive collaborative potential. According to recent discussions, Bucky Barnes, played by Sebastian Stan, is leading the New Avengers alongside Yelena Belova. While rumors swirl about Stan appearing as a Captain America variant, the actor remained reserved during an appearance at Tokyo Comic-Con.
“I don’t know if I can say very much about that,”
said Stan.
“I don’t know what’s going to happen. We’ll see who makes it or who doesn’t. I think the most exciting thing is Robert Downey Jr., one of the greatest, coming back. He’s definitely going to have something in store for everybody.”

Stan’s guarded comments have fueled fan theories about impending major character deaths. The storyline may follow Marvel’s Secret Wars comic arc, where few heroes and villains survived, setting expectations for high stakes and emotional farewells. In that comic, only a limited number reached Doctor Doom’s mysterious Battleworld, signaling the possibility that Doomsday could be similarly consequential for many beloved characters.
Behind the Scenes and Cast Experience
During the Tokyo panel, Sebastian Stan reflected on the camaraderie and energy of working on Thunderbolts*, an MCU film with several cast members also involved in Avengers: Doomsday.
“We had a lot of fun. It was a great group of people, and everybody was very funny. David Harbour and Wyatt Russell, and Florence Pugh, [who is] really very talented. It was just a good time. If you guys liked the movie, help us make another one. We could film it here!”

This glimpse behind the scenes highlights the supportive dynamic among franchise newcomers and established MCU actors, including those making their Avengers franchise debuts such as Wyatt Russell, Simu Liu, Tenoch Huerta Mejia, Florence Pugh, Danny Ramirez, David Harbour, Hannah John-Kamen, and Lewis Pullman.
Perspectives from MCU Veterans
Elsewhere in the Marvel universe, Hawkeye actor Jeremy Renner recently shared his thoughts about the MCU’s evolution and his character’s journey. On a podcast appearance, Renner spoke fondly of his work on the Hawkeye series and the resonance of family themes in the narrative.
“I really enjoyed doing the series version because it was a bit more intimate and had family dynamic, which is always a huge part of which I think sort of Clint’s kind of superpower is.”

“He is such a human side of being a superhero. He’s one of the few,”
Renner continued.
“But I think his superpower is that sort of grit of the human condition, that is, loyalty and family. Otherwise, what are you fighting for?”

Renner also confirmed that, although Hawkeye Season 2 appeared delayed, positive developments are emerging.
“We were trying to do a second season,”
the actor noted.
“I think I will get strong enough to be able to do it. We will work it out. It’s going to be great.”
— Jeremy Renner, Actor
The timeline for a second Hawkeye season may now depend on how events unfold in Avengers: Doomsday and subsequent MCU phases, with indications from Marvel Studios that there could be space for new projects after Avengers: Secret Wars in 2027.
All-Star Ensemble and Creative Team
The cast list for Avengers: Doomsday is stacked with iconic talent. Confirmed stars include Chris Hemsworth, Anthony Mackie, Winston Duke, Tom Hiddleston, Sebastian Stan, Letitia Wright, Paul Rudd, and Robert Downey Jr. Joining them for their Avengers debut are actors like Wyatt Russell, Simu Liu, Tenoch Huerta Mejia, Florence Pugh, Danny Ramirez, David Harbour, Hannah John-Kamen, and Lewis Pullman.
Leads from The Fantastic Four: First Steps—Pedro Pascal, Vanessa Kirby, Ebon Moss-Bachrach, and Joseph Quinn—will join the battle, along with established X-Men actors Kelsey Grammer, Patrick Stewart, Ian McKellen, Alan Cumming, Rebecca Romijn, and James Marsden. There’s also the addition of Channing Tatum, noted for his upcoming role in Deadpool & Wolverine.
Veteran directors the Russo Brothers are helming the film, working with screenwriter Stephen McFeely, both known for previous Marvel hits including the Avengers and Captain America films. Michael Waldron, who contributed to Loki and Doctor Strange in the Multiverse of Madness, is also involved in scripting.
Looking Ahead to Release and Impact
