Pepper Potts is not on the official cast of Avengers: Doomsday. Marvel’s own guide to the movie, updated on November 5, 2026, lists 32 actors and their characters, and Gwyneth Paltrow isn’t among them.
That matters because the clock is running. Avengers: Doomsday opens in theaters on December 18, 2026, and the question of whether Tony Stark’s widow shows up comes back every time Paltrow trends.
The list Marvel actually published
The Marvel.com guide is the closest thing to an official answer. It names Robert Downey Jr. as Victor Von Doom, along with Chris Evans as Steve Rogers, Chris Hemsworth as Thor and Pedro Pascal as Reed Richards, plus X-Men veterans Ian McKellen and Patrick Stewart.
Pepper Potts isn’t there, under her own name or as Rescue, the armored identity she took on in the films.
Paltrow says she doesn’t know either
The actress hasn’t settled it herself. In a March 2025 Instagram Q&A, she answered a fan directly: “The truth is, I don’t totally know. I think I might, but I’m not sure. Nothing is confirmed,” as ComicBook.com reported.
Nine months later, she was promoting Marty Supreme on Good Morning America on December 15, 2025, when George Stephanopoulos asked whether she’d return in Doomsday. Her answer came with a smirk: “I don’t know. I’m not sure I’ve heard of that one.”
The claims that she’s in the movie come from online insiders, not from Marvel or the trade press. In September, 9to5Marvel noted that versions of the rumor have circulated since early 2026 without ever being confirmed.
Why fans keep asking
Pepper has been part of the franchise from day one. Paltrow first played her in Iron Man in 2008, the movie that launched the Marvel Cinematic Universe. She last appeared as the character in Avengers: Endgame in 2019, the film where Tony Stark dies.
Downey’s return is what reopened the door. He’s back, but as Doom, not as Tony. In a 2023 Instagram Q&A, Paltrow explained her own absence bluntly: “Why do you need Pepper Potts without Iron Man?” With Downey wearing a different mask, fans want to know if Pepper comes with him.
A cast list can’t rule out a surprise cameo. But as of November 9, 2026, there is no official confirmation that Pepper Potts is in Avengers: Doomsday.
