Watch Harrison Ford Hulk Out Onstage at Marvel Studios' San Diego Comic-Con Panel

"What is a Red Hulk?" That's how Harrison Ford, who plays U.S. President Thaddeus "Thunderbolt" Ross in the upcoming Captain America: Brave New World, responded when asked about his then-rumored Marvel role as Red Hulk in a 2023 interview with ComicBook. One year later, the iconic Star Wars and Indiana Jones actor hulked out onstage in Comic-Con's Hall H after a just-released trailer showed the Red Hulk smashing through the White House before being engaged by Anthony Mackie's vibranium-winged Captain America.

Ford, 82, takes over the late William Hurt's role as the mustached Thaddeus Ross from 2008's The Incredible Hulk and 2016's Captain America: Civil War . "I would have grown a mustache if I'd been asked," Ford said as Mackie interjected with: "Tell Tom Holland I've got Harrison f---ing Ford," referring to his long-running "feud" with the Spider-Man star.

"This is a character that's based on a lot of history developed with Bill, who played the character previously," Ford said. "But now, I am Thaddeus, and I'm delighted. And I'm proud to become a member of the Marvel universe. I've been watching fantastic actors -- some of which are here tonight -- have a really good time working in the Marvel universe, and I wanted a piece of the action."

"I'm very proud to be in this film. I think it has turned out to be fantastic," Ford added of the Julius Onah-directed fourquel that also stars Danny Ramirez as the new Falcon, Shira Haas as former Black Widow Ruth Bat-Seraph, Giancarlo Esposito as the Serpent Society's Sidewinder , and Tim Blake Nelson as Samuel Sterns/the Leader.

While there were rumors that Ford would reprise his role as the recast Ross in both Captain America: Brave New World and Thunderbolts* , Marvel Studios president Kevin Feige confirmed during a panel for the latter that Ford's character isn't in that film (which hits theaters May 2025). Feige also revealed that the government-backed Thunderbolts team isn't named after the former Army general-turned-president.

Footage screened for the convention crowd included references to the new Avengers, the half-risen Celestial Tiamut from 2021's Eternals , and adamantium, the virtually indestructible steel alloy that is found in Captain America's shield and which is fused to Wolverine's skeleton by the government's Weapon X program.

Feige ended the Captain America 4 segment of the presentation by saying: "Just when I think my dream of a nerdy life can't get any more complete, I hear Harrison Ford say 'adamantium.'"

Captain America: Brave New World opens only in theaters February 14th, 2025.
