Ryan Reynolds and Hayley Atwell will return as Deadpool and Peggy Carter respectively in the upcoming film Avengers: Doomsday, Marvel Studios confirmed at San Diego Comic Con. Both actors made an appearance on stage in Hall H during the studio's announcement panel.
Reynolds, in character as Deadpool, joined the panel and referred to his attire as a "Canadian tuxedo." He humorously inquired about the filming schedule for Avengers: Doomsday from directors Joe and Antony Russo, who indicated that principal photography was complete but post-production work was ongoing. While the exchange was framed with humor, the confirmation solidifies Deadpool's inclusion in the film, with Reynolds' scenes presumably already filmed.
This announcement was made during Marvel's presence at Comic Con 2026, where numerous other news and updates from the studio were shared.
