Sandra Hüller joins the cast in a mystery role
Sandra Hüller, who played Eva Stratt in Project Hail Mary, will make a cameo in Avengers: Doomsday, according to The Hollywood Reporter. Her character remains under wraps.
Benedict Cumberbatch says he’s returning as Doctor Strange
Cumberbatch initially said Doctor Strange would sit out Doomsday. When Business Insider followed up, he revised his answer: “I got that wrong, I am in the next one.” He then joked that fans should never believe anything he says. Marvel has yet to include him on its published cast list.
Kevin Feige confirms Doctor Doom is not a Tony Stark variant
Robert Downey Jr. spent more than a decade playing Tony Stark, so when Marvel unveiled him as Doctor Doom, fans wondered whether the villain might be another universe’s version of Iron Man. Marvel Studios president Kevin Feige addressed that theory in an interview with Empire by pointing to another actor in the Doomsday cast.
“Is Steve Rogers a Johnny Storm variant?” Feige asked. Chris Evans played the Human Torch in two Fantastic Four films before he picked up Captain America’s shield, and audiences recognize them as separate characters. Asked whether casting Downey was a shortcut to bringing back Tony Stark, Feige said, “The answer is no. He’s Victor Von Doom.”
The Russos compare Doom and Thanos
“Doom is a Gothic character. He says, ‘Hell answers to me,’ and he’s not kidding. He’s a very powerful character with some very dark magic, and he’s not above selling his soul to get what he wants. He’s worth being scared of”
“He’s a father who’s a victim of trauma. He has lost a child. When people see the film they say it’s a very scary movie. It’s scary because he’s so profoundly damaged”
“Doom is much more ego-driven than Thanos. Thanos believed he was serving a greater good”
Doctor Doom seems to be assembling a team
Spoilers for VisionQuest and Avengers: Endgame Encore follow.

Doom has already sought out two of Marvel’s most powerful characters. In the VisionQuest finale, he finds Elizabeth Olsen’s Wanda Maximoff beneath the rubble of Mount Wundagore, where she appeared to die in Doctor Strange in the Multiverse of Madness. Doom tells her to wake up. She opens her eyes.
Doom also comes for Mark Ruffalo’s Bruce Banner in a scene added to the theatrical rerelease of Avengers: Endgame. Banner has isolated himself in an underground bunker to keep others safe from the Hulk. Doom finds him there and takes him captive, describing what he’s doing as “collecting.”
Together, the scenes suggest Doom is gathering people for a larger plan. Neither Wanda nor Banner has agreed to fight for him on screen. The idea that he’s taking them to Battleworld ahead of Avengers: Secret Wars remains a theory.
Ryan Reynolds and Hugh Jackman receive writing credits

The Writers Guild of America lists Ryan Reynolds and Hugh Jackman under “additional literary material” for Avengers: Doomsday. Stephen McFeely, who co-wrote Avengers: Infinity War and Endgame, shares the screenplay credit with Loki creator Michael Waldron.
The listing confirms that both Deadpool & Wolverine stars contributed to the writing. It doesn’t identify which scenes they worked on, and Marvel has yet to announce an on-screen appearance for either Deadpool or Wolverine.
Kevin Feige says the film explores the consequences of years without an Avengers team
“We’re coming out of years of seemingly no organised Avengers team, and that’s exactly when they face these incursions. That’s always fun, to put your heroes on the back foot.”
Avengers: Doomsday opens December 18, 2026
Avengers: Doomsday opens in U.S. theaters on December 18, 2026. Marvel’s synopsis puts heroes from three universes on a collision course. The footage already brings some of them face to face: Steve Rogers reunites with Thor, Sam Wilson meets the Fantastic Four, and Doom stops Thor’s axe, Stormbreaker, in its tracks.
