Tom Holland's Brother Harry Has a Secret Cameo in 'Deadpool & Wolverine'

Harry Holland, the younger brother of 'Spider-Man' star Tom Holland, plays a version of Deadpool in the recently released Marvel film.

Another Holland has entered the Marvel Cinematic Universe! Deadpool & Wolverine's supervising stunt coordinator, George Cottle, recently revealed that Tom Holland's younger brother Harry Holland had a secret cameo in the most recent Marvel feature entry. 

On Tuesday, Cottle shared a behind-the-scenes photo of Harry, 25, in a Deadpool costume with the mask off to his Instagram Story. He explained that Harry was a "special guest star" for the stunt team arranged by film director Shawn Levy and Ryan Reynolds.

"When Shawn Levy and Ryan Reynolds set the bar so f'ing high, even the stunt team needed a special guest star!!," Cottle wrote on the slide. "It may not be the Holland the world wanted, but it was the Holland we all needed!!"

In a sweet note to Harry, Cottle added, "You smashed it my friend! #haroldpool."

Reynolds, 47, reshared the post on his Instagram Stories and joked, "This is how I find out?!? You tell me?" 

Cottle cheekily responded, "All good things come to those who wait sir."

Harry's brother Tom, 28, famously stars as Peter Parker, a.k.a. Spider-Man, in the Marvel Cinematic Universe. Tom doesn't make an appearance in Deadpool & Wolverine -- although both Reynolds and Hugh Jackman have been vocal about wanting to star in a film alongside his Spidey one day -- but many other celebrities make unexpected and highly rumored appearances in the epic action flick.

During San Diego Comic-Con's Deadpool & Wolverine panel discussion on Thursday, film stars Reynolds, Jackman, Emma Corrin, director Levy and Marvel Studios president Kevin Feige welcomed some special friends on stage for some spoiler-heavy Comic-Con cameos.

The stars were joined by Dafne Keen, Jennifer Garner, Channing Tatum, Wesley Snipes and Chris Evans after gifting fans with a special screening of the movie itself.

One special moment between Reynolds and Snipes was particularly remarkable. The pair reportedly had a contentious relationship when they starred together in Blade Trinity, but appears they've managed to patch up their working relationship and friendship in the 20 years that have since passed.

The surprise screening came just hours after Reynolds, Jackman, Corwin, Evans and Levy were in Los Angeles with Feige for the Marvel Studio president's star ceremony on the Hollywood Walk of Fame.

ET spoke with Feige at the event, and he reflected on his stewardship of the massive Marvel Cinematic Universe.

"It's always been dream after dream for me at Marvel with the highest of highs and a little bit of lows and back to high of highs," Feige, 51, shared. "It's the journey! And it's the journey with all these people who are here with me today."

When asked about which of the many beloved Marvel characters stand out as his favorite, Feige reflected, "There are a lot!"

"I mean, even being here with Hugh today, going back from his first audition on X Men one 25 years ago to him opening tonight in Deadpool & Wolverine, he's had an amazing journey," shared Feige. "I think Chris Evans, who's here today, and what he has done with the Cap character (Captain America) from the First Avenger to Endgame, I love them all."

"And Tony Stark, of course (Iron Man), and what Robert [Downey Jr.] did with [director] John Favreau," he added. "[They] helped us create and really start the whole MCU."
