Ryan Reynolds walked the San Diego Comic-Con floor in a grey Deadpool suit, blending in with thousands of fans before crashing Marvel's Hall H presentation — and he posted the whole thing online for everyone to see.

The video, shared on 27 July 2026 from Reynolds's X account @VancityReynolds, shows the actor in full costume navigating the San Diego Convention Center among attendees who had no idea a movie star was walking past them (Deadline). Reynolds posted it with a message that tied the stunt to a decade of history: "The fans got Deadpool off the ground so many years ago." He added: "Yesterday, 10 years after the first film and exactly 2 years after Deadpool & Wolverine, I felt so lucky to be on the #SDCC floor with everyone whose unapologetic devotion brings so much joy to this world."

The behind-the-scenes footage also captured the payoff. On stage at Hall H — the 6,500-seat venue where studios stage their biggest Comic-Con reveals — Robert Downey Jr., who plays Doctor Doom in the upcoming Avengers: Doomsday, spotted Reynolds from the crowd. "Who's this guy with the swords and stuff?" Downey asked, according to the video. Reynolds stepped to the mic and replied: "Long-time listener, first-time caller." The crowd roared. He then quipped: "This seems an awfully expensive way to announce a film. When do you start filming?" (Deadline). The Associated Press confirmed that Reynolds crashed the panel from the audience (AP).

The Hall H panel also featured Ryan Gosling, whose role in the Marvel slate has drawn considerable attention (AP).

The Comic-Con surprise came the week after Reynolds teased the future of the franchise at New York's Fantastic Fest. There, he told attendees: "There's eventually, remotely another Deadpool film. It's going to be great." He hinted at creative direction, saying: "There's a few really deep cuts that I think are missing behind the movies," and name-checked Deadpool co-creator Fabian Nicieza and comic writer Gerry Duggan as influences (Deadline).

The Deadpool character has travelled a long road to this point. Reynolds first played a version of the character in X-Men Origins: Wolverine (2009). Test footage of Reynolds as Deadpool leaked in 2014, and the fan response helped push the standalone film into production. The first Deadpool arrived in 2016 and earned Reynolds a Golden Globe nomination. Last year's Deadpool & Wolverine grossed $1.3 billion globally, pushing the franchise past $2 billion in total worldwide box office (Deadline).

For fans, the Comic-Con walkabout was a callback to the franchise's origins in grassroots enthusiasm — the same energy Reynolds credited a decade ago for getting the first film made. Whether that "eventually, remotely" fourth film materialises is, by Reynolds's own word, still a ways off. But an actor suiting up to walk the convention floor among the people who made the character a phenomenon is its own kind of announcement.
