David Harbour Hints ‘Avengers: Doomsday’ Will Test Red Guardian and Yelena’s Father-Daughter Bond

The ‘Black Widow’ prequel series within the Marvel Cinematic Universe has proven to be one of the franchise’s most emotionally resonant storylines, centering on the complex familial relationships forged between unlikely characters thrust into extraordinary circumstances.

Among the most compelling dynamics to emerge from this narrative thread has been the bond between David Harbour’s Red Guardian and Florence Pugh’s Yelena Belova, a connection that began as antagonistic but evolved into genuine affection and mutual respect across their shared MCU appearances. Now, as the massive ensemble event ‘Avengers: Doomsday’ approaches, the actor has opened up about what the upcoming film means for this cherished relationship.

The characters first connected in the 2021 film ‘Black Widow,’ where Harbour portrayed Alexei Shostakov, a former Soviet super-soldier and reluctant father figure to both Scarlett Johansson’s Natasha Romanoff and Florence Pugh’s Yelena.

Their relationship was further explored and deepened in the recent ‘Thunderbolts*,’ which brought together a team of reformed anti-heroes and misfits from across the MCU. The chemistry between Harbour and Pugh resonated with audiences, establishing them as one of the franchise’s most endearing character pairings despite their complex history.

During an interview at the premiere of his new series ‘DTF St. Louis,’ Harbour was asked to discuss his upcoming return as Red Guardian in ‘Avengers: Doomsday,’ directed by Anthony and Joe Russo. According to a report from Deadline, Harbour teased that the relationship between his character and Yelena will undergo significant strain as the events of the 2026 film unfold. “You know that Yelena Belova and Red Guardian have a connection. If you saw ‘Thunderbolts*,’ you know how much they love each other and how much they’re trying to help each other. And Doomsday will affect that relationship,” he shared.

The implications of Harbour’s comment suggest that the catastrophic events surrounding Robert Downey Jr.’s return as Doctor Doom, the central threat of ‘Avengers: Doomsday’, will place enormous pressure on the bonds that these characters have forged. Rather than allowing their familial connection to provide comfort and support, the film appears set to weaponize their relationship as a source of conflict or tragedy.

This tonal shift represents a significant escalation from the more intimate character moments audiences experienced in ‘Thunderbolts*,’ which focused heavily on these anti-heroes finding purpose and belonging within their makeshift family.

Harbour also confirmed during his ‘DTF St. Louis’ interview that he has been extensively involved in reshoots and additional filming for the sprawling MCU event. He mentioned his upcoming travel schedule, noting that he would be heading to different locations to continue work on the film. These reshoots suggest that Marvel Studios and the Russo Brothers continue to refine the massive ensemble’s screen time and character arcs as the December 2026 release date draws closer.

Beyond his work with Yelena, Harbour revealed that he is building significant chemistry with other members of the Thunderbolts roster who are carrying over into ‘Doomsday.’ He mentioned developing a “brotherhood” with Sebastian Stan’s Winter Soldier and Wyatt Russell’s U.S. Agent, describing their dynamic as a fun “bromance.” This expanded character focus indicates that the former anti-hero team will occupy a central place in the film’s ensemble structure.
