Let’s start with what the reshoots actually confirm, because the discourse has gotten so fixated on one disputed name that the confirmed ones are getting buried.
Elizabeth Olsen is filming new material for Avengers: Doomsday. So are Brie Larson and Teyonah Parris. That’s Captain Marvel, Monica Rambeau — and Scarlet Witch. Three significant characters who weren’t part of the March 2025 cast reveal livestream, all of them now confirmed to be part of the film’s April reshoot window. According to reporting from SuperheroHype, this additional photography is underway now.
The She-Hulk debate — entertainment journalist Michael Roman reported she’d appear, scooper James Mack disputed that claim on April 2, suggesting what Roman saw was concept art that may not have made it to the final cut — is the part of this story generating the most heat. It’s also the least important part. We’ll get to it.
Wanda’s Return Is the Real Story
Scarlet Witch “died” at the end of Doctor Strange in the Multiverse of Madness in 2022. Corrupted by the Darkhold, she pulled Mount Wundagore down on herself in the film’s climax — a sacrifice framed as self-punishment after everything she’d done in pursuit of a version of her children. It was a blunt ending for one of the most complicated characters in the MCU’s Phase Four run, and a lot of fans never fully accepted it. Wanda Maximoff, across WandaVision, Infinity War, and Endgame, had been positioned as the MCU’s most powerful hero. Ending her arc on an island collapsing on top of her felt unfinished.
The Multiverse gives Marvel an obvious way back, and they’re clearly taking it. Which variant returns, under what circumstances, and whether she’s a threat or an ally to the assembled Avengers — none of that is confirmed yet. But Elizabeth Olsen filming for Doomsday means Wanda is in this film in some capacity, and after three years of absence, that’s the headline.
For context on just how significant her power level is in the MCU’s own internal logic: our Dr. Doom vs. Sentry breakdown covers the ceiling of what Doomsday’s major players can do, and Scarlet Witch sits at or above that tier on her best day. However Marvel uses her here, it will matter.
What the Confirmed Names Tell Us
The three confirmed reshoot additions point to something specific about where Doomsday’s story is going. Larson’s Captain Marvel and Parris’s Monica Rambeau both have unresolved threads from The Marvels — a film that ended with Monica trapped in an alternate universe, separated from her mother, with no resolution in sight. Pulling both characters into Doomsday’s reshoots suggests the Multiverse crossover structure of this film is even more expansive than the March cast announcement indicated. Monica’s situation in particular seems like exactly the kind of loose thread the Russos would want to address in a film about reality fracturing.
Three characters who weren’t confirmed in the original announcement, all added in the same reshoot window. That’s not random. That’s Marvel filling specific narrative gaps they identified in the edit.
The She-Hulk Question
Here’s what we actually know: Michael Roman reported She-Hulk would appear in Doomsday. James Mack pushed back on April 2, noting that as of his information, she wasn’t in it — and specifically suggested Roman’s sourcing may have been concept art rather than confirmed casting. Mack added that he saw considerable art placing her on Sam Wilson’s Captain America team, which suggests She-Hulk’s Doomsday appearance was at least planned at some point.
Tatiana Maslany hasn’t appeared in the MCU since She-Hulk: Attorney at Law wrapped in 2022. She’s been publicly candid about some friction with Disney’s approach to the project, though reports have indicated that friction doesn’t extend to her relationship with Marvel Studios specifically. Whether that translates into a Doomsday appearance or a Secret Wars debut or nothing at all — nobody has confirmed it cleanly either way.
The honest read: this is two reporters with conflicting information on a film that isn’t out for nine months. Mack’s counter is worth noting. It’s not a verdict.
What the Reshoot Window Means for the Film
Doomsday wrapped principal photography in September 2025. Reshoots in April 2026 — eight months later — with a December 18 release date isn’t unusual for a film of this scale. THR had flagged a “healthy” amount of additional photography was expected. That said, adding three characters who weren’t in the original cast announcement suggests the Russos and Feige identified meaningful gaps in the ensemble in the edit room, not just visual effects cleanup.
That’s how you end up with Scarlet Witch. She’s not cleanup. She’s an addition.
