The Big Reveal: David Jonsson Is the New Black Panther
During Marvel Studios' Hall H panel on Saturday, July 25, 2026, director Ryan Coogler announced that actor David Jonsson will take on the role of Black Panther in the upcoming third film. The announcement came almost six years after Chadwick Boseman's death in August 2020, and was met with a standing ovation from the Comic-Con crowd. Jonsson appeared onstage alongside Coogler, "Black Panther" co-stars Letitia Wright and Winston Duke, and Marvel Studios president Kevin Feige.
Visibly moved by the moment, Jonsson thanked the cast and crew for the honor and the privilege and the blessing to join them, addressing the crowd before asking to let the work speak for itself rather than saying more in the moment.
Who Is David Jonsson?
Jonsson is a rising British actor best known for his roles in Stephen King adaptation "The Long Walk," the 2024 sci-fi hit "Alien: Romulus," and as Gus Sackey in the first two seasons of the HBO/BBC drama "Industry." Coogler specifically praised Jonsson's recent work before making the announcement, and both of Jonsson's recent major films had their own Hall H presentations in prior years, keeping him within Comic-Con's orbit before this announcement. Winston Duke, who plays M'Baku, has publicly expressed confidence in Jonsson joining the franchise, describing his own approach as trusting Jonsson as a fellow artist.
How the Character Fits Into the Story
Jonsson will play Prince T'Challa II, also known as Toussaint, the son of T'Challa and Nakia, who was introduced in the closing scene of 2022's "Black Panther: Wakanda Forever." Coogler confirmed that the character comes of age in the third film, marking what several outlets have described as a genuine passing of the torch — distinct from Letitia Wright's Shuri, who took up the Black Panther mantle in "Wakanda Forever" following T'Challa's death within the story itself.
Ryan Coogler Returns to Direct
Coogler, who directed both prior "Black Panther" films, confirmed he will return to direct the third installment. Coogler also revealed the film will be shot entirely on large-format celluloid film, a first for the Marvel Cinematic Universe, signaling a notable visual and technical departure for the franchise's third chapter.
Black Panther 3's Release Date and Production Details
Black Panther 3 is scheduled for release on December 15, 2028. Denzel Washington, previously announced as part of the cast, remains attached to the project alongside Jonsson, Wright, and Duke. Specific plot details beyond T'Challa II's coming-of-age arc have not been disclosed.
Avengers: Doomsday — Hayley Atwell's Confirmed Return
The same Hall H panel confirmed that Hayley Atwell will reprise her role as Peggy Carter in "Avengers: Doomsday," ending months of speculation about her involvement in the film. Atwell first played Peggy Carter in 2011's "Captain America: The First Avenger" and has since appeared across multiple MCU projects, including her own series "Agent Carter," as well as a Captain Carter variant in "Doctor Strange in the Multiverse of Madness." Given Doomsday's heavily multiverse-focused plot, which follows Chris Evans's Steve Rogers returning to the past in the film's teaser material, fan speculation has centered on which specific version of Peggy Carter Atwell will portray.
Avengers: Doomsday is scheduled for release on December 18, 2026.
What About Ryan Reynolds and Deadpool?
This is where some nuance matters. Ryan Reynolds appeared at the Hall H panel in character as Deadpool, wearing a new grey suit he jokingly referred to as his "Canadian tuxedo," and bantered with the panel about a potential cameo. However, according to reporting from the panel itself, Reynolds' actual appearance in Avengers: Doomsday has not been formally confirmed by Marvel Studios in the same way Atwell's role was — reporters covering the panel described it as very likely, given Reynolds' in-character presence and the joking exchange about filming already being complete, rather than an official cast confirmation. Readers should treat Deadpool's specific appearance in the finished film as highly probable but not yet officially confirmed in the way Atwell's role was.
The Full Doomsday Cast, So Far
Alongside Atwell, the Hall H panel brought out a large roster of confirmed Avengers: Doomsday cast members, including Robert Downey Jr., Chris Evans, Pedro Pascal, Paul Rudd, Anthony Mackie, Simu Liu, James Marsden, David Harbour, Letitia Wright, Lewis Pullman, Kelsey Grammer, Danny Ramirez, Winston Duke, Hannah John-Kamen, Rebecca Romijn, and Tenoch Huerta. The film is described by Marvel as an ensemble "existential epic" bringing together heroes from multiple universes.
Honoring Chadwick Boseman's Legacy
Boseman first appeared as T'Challa in 2016's "Captain America: Civil War" before headlining 2018's "Black Panther," a film that grossed $1.3 billion worldwide and earned seven Oscar nominations, including Best Picture — a genuine cultural milestone as Marvel's first film centered on a Black superhero. Boseman died of colon cancer in August 2020 at age 43, while Coogler was working on the film's sequel. "Wakanda Forever" ultimately addressed his death within the story itself, with Shuri taking up the mantle rather than recasting T'Challa directly. Jonsson's casting as T'Challa's now-grown son represents a different approach: continuing the bloodline and legacy of the character rather than replacing the original role.
Case Studies: How Other Franchises Have Handled Recasting
In-story tribute over direct recasting: Marvel's decision to have Shuri assume the Black Panther identity in "Wakanda Forever," rather than recasting T'Challa immediately after Boseman's death, reflects a broader industry pattern of handling an actor's death within the narrative itself rather than simply substituting a new actor into the same role.
Generational passing of the torch: Introducing T'Challa II as a coming-of-age character for Jonsson to portray gives Marvel a narrative path to continue the character's legacy without directly recasting the specific role Boseman originated, a strategy that offers emotional continuity while giving the new actor creative room to make the character his own.
Common Questions Fans Are Asking
- Is David Jonsson playing the exact same T'Challa that Boseman played? No — he's playing T'Challa's son, T'Challa II (Toussaint), not a recast of the original character.
- Does this mean Letitia Wright's Shuri is being replaced as Black Panther? Wright is confirmed to return for Black Panther 3, though the film's marketing centers on T'Challa II's arc rather than positioning it as a direct replacement of Shuri's role.
- Was Ryan Reynolds' Doomsday cameo officially confirmed? Not in the same formal way as Atwell's role — his panel appearance strongly suggested involvement, but wasn't presented as an official cast confirmation.
What to Watch For Next
Expect further details on Black Panther 3's plot, supporting cast, and marketing materials to emerge gradually over the roughly two years before its December 2028 release. For Avengers: Doomsday, with a December 2026 release date now just months away, additional trailers, full cast confirmations, and marketing rollout are likely to accelerate significantly in the coming weeks.

Conclusion

David Jonsson's casting as T'Challa's son offers a way to honor Chadwick Boseman's legacy while giving the franchise a genuine new chapter, and Ryan Coogler's return signals continuity in creative vision. Meanwhile, Hayley Atwell's confirmed return for Avengers: Doomsday closes a long-running rumor, even as Ryan Reynolds' specific involvement remains, for now, strongly suggested rather than formally confirmed. With both films now anchored to firm release dates, expect the marketing rollout for both to intensify significantly over the coming months.
