Sandra Hüller is reportedly joining the cast of Avengers: Doomsday, a Marvel film directed by Joe and Anthony Russo, set for release on December 16. Hüller, an acclaimed German actress, has previously appeared in Anatomy of a Fall, which earned her recognition at the César Awards and the Berlin Film Festival. She has also acted in Last Chance Project alongside Ryan Gosling and Digger with Tom Cruise. She may appear in the film Fatherland on December 2, possibly marking the end of her 2026 schedule with this new role. According to the British Stunt Register, a professional organization for British stunt performers, Hüller will serve as a stand-in for Hayley Atwell, Katya Hazel Boirand, Josie Pocock, and herself in Avengers: Doomsday. This suggests she may have a role in the film, though it had not been officially confirmed. An anonymous internet user speculated on Reddit that Hüller might play a witch in the film, referencing a costume photo revealed at San Diego Comic-Con. The film’s poster includes characters linked to Dr. Doom (Robert Downey Jr.), such as Scarlet Witch (Elizabeth Olsen), Cléa (Charlize Theron), and Sylvia (Sophia DiMartino), who are depicted as part of the Latverian witches. The addition of Hüller raises questions about the film’s storyline, potentially introducing a new or alternate character. Hugh Jackman, who plays Wolverine, denied any involvement in the next two Marvel crossovers when interviewed by Variety. His response mirrors Andrew Garfield’s past denial of involvement in a Marvel project. Earlier, the Russo brothers had dismissed theories about Doomsday during discussions about Avengers: Endgame additional scenes. However, recent developments suggest the film may still have surprises in store.
