Avengers: Doomsday Casts Sandra Hüller in Cameo Role

Marvel has reportedly cast Sandra Hüller in Avengers: Doomsday for a secret cameo role.

Information about the last-minute addition comes from The Hollywood Reporter , which said the Project Hail Mary star will appear on screens when Earth's Mightiest Heroes take on Robert Downey Jr.'s Doctor Doom this December. Although much of that cast and their parts in the movie have been confirmed, details about Hüller's role were not shared.

Marvel Studios and directors Joe and Anthony Russo almost certainly have plans for plenty of superhero moments and surprises. How Hüller fits into that plan remains to be seen, but considering fans had already speculated about her involvement in recent days, some of the less patient Marvel Cinematic Universe enjoyers are probably already doing their best to piece together Doomsday's mysteries early.

Hüller is a German actor with a decades-long career on movie and TV screens. She was nominated for Actress in a Leading Role at the 2024 Oscars for her part in Anatomy of a Fall, but is also known for her parts in films like Digger, The Zone of Interest, and Fatherland. If you missed her in any of those movies, there's a good chance you caught her playing Eva Stratt, a role that we called one of the best parts of Ryan Gosling's Project Hail Mary .

As for her Marvel introduction, all we know for now is that she'll appear in a cameo part, meaning she probably won't show up for much of its 2-hour-and-45-minute runtime . Like major stars – including Harry Styles and Charlize Theron – before her, it's possible that we could only see Hüller's character during a stinger moment shown during the film's credits sequence. There's at least little reason to suspect that's not on the table, especially considering Marvel will use Doomsday's plot to set up the release of Avengers: Secret Wars in December 2027.

Doomsday is out in just a few short months, but that clearly hasn't stopped Marvel from revealing new information for what's gearing up to be one of the year's biggest releases. Even more about the movie is expected to be revealed at the MLB World Series , which is just a few hours after this piece's publication. THR noted that the Russo brothers are knee-deep in post-production for the film ahead of its December 18, 2026, premiere.
