David Harbour has revealed that the highly anticipated Avengers: Doomsday is undergoing reshoots, with the actor preparing to return to the set soon. This confirms ongoing work on the film, which features Harbour reprising his role as Red Guardian in the Marvel Cinematic Universe’s massive crossover event.
David Harbour’s Role and Anticipation for the Film
While much of the buzz around Avengers: Doomsday centers on surprising returns like the X-Men, Steve Rogers, and Loki, core MCU characters remain key to the crossover’s scale. David Harbour stands out as a returning mainstay, stepping back into the role of Red Guardian. In a recent interview with ExtraTV, Harbour spoke cautiously but excitedly about the film, hinting at the large-scale nature of the project and a reunion with his Thunderbolts co-stars Wyatt Russell and Sebastian Stan.
“I’m really excited about it. The chemistry with Sebastian [Stan] and Wyatt [Russell] on set was fantastic, so I’m looking forward to getting back in there. You know I can’t say anything. But it’s gonna be fun. The Russos are killing it, and the whole thing is shaping up to be massive.”

Reshoots Confirmed as Part of Final Production Phase
Harbour’s anticipation to return to filming confirms that Avengers: Doomsday will feature reshoots soon. His involvement as Red Guardian suggests this additional footage may play a role in strengthening the storyline, particularly involving the New Avengers team. Although specific details about the reshoots have not been disclosed, Harbour’s comments provide clear evidence of continued work on the film.
“I’ve been working a lot. Keeping busy. And this little Avengers movie that we got in London. They got a couple more days they want to do. I’m heading there soon [and] actually going to London for a couple of days. There’s a little more filming coming up for Avengers: Doomsday.”

It is important to note that reshoots are a common practice for blockbuster films like this, especially with complex scheduling for stars and directors involved. The lengthened timeline for principal photography likely meant that Harbour’s scenes were only edited together recently, necessitating additional filming to finalize the narrative.
Looking Forward to the Film’s Release and Impact
Avengers: Doomsday is slated for release in December 2026, and the confirmed reshoots signal continued commitment to perfecting the film’s storytelling and visuals. Fans can expect Harbour’s Red Guardian to have an active role in the unfolding crossover, alongside familiar faces like Sebastian Stan and Wyatt Russell. As Marvel continues to expand its cinematic universe, these reshoots highlight the care taken to deliver an impactful and well-crafted event to theaters worldwide.
