Developed over time first seen 3 weeks ago
Marvel Studios has confirmed that Ryan Reynolds and Hayley Atwell will reprise their roles as Deadpool and Peggy Carter in Avengers: Doomsday, revealing the news in person during the studio's Hall H panel at San Diego Comic Con. The appearance adds two well-known fan-favourite characters to the film's already large ensemble cast, further building anticipation ahead of its December release.
Reynolds appeared in character as Deadpool, now sporting a grey suit he jokingly dubbed his "Canadian tuxedo", and bantered with directors Joe and Anthony Russo, asking when filming would start so he could make a cameo. The Russos revealed that shooting has already wrapped, though the film is still being fine-tuned, strongly suggesting Reynolds' scenes were shot some time ago. Avengers: Doomsday remains scheduled for release on 18 December 2026.

Marvel's next big crossover film, Avengers: Doomsday, is one of the studio's most ambitious projects to date, bringing together characters from across its various franchises into a single story. It is being directed by Joe and Anthony Russo, who previously directed several major Avengers films, and is due for release on 18 December 2026.
Ryan Reynolds plays Deadpool, a wisecracking, foul-mouthed antihero previously seen in his own trilogy of films, while Hayley Atwell plays Peggy Carter, a character with roots in the Captain America films and television spin-offs. Both actors are well established within Marvel's franchise and have large existing fan followings, so their involvement is of particular interest to audiences tracking who will appear in the film's large ensemble cast.
San Diego Comic Con is a major annual entertainment convention in California where studios often reveal casting news and other announcements to a large audience of fans and press, making it a common venue for this kind of reveal.
