The director of Captain America 4, Julius Onah, recently discussed the decision to reveal Harrison Ford’s role as Red Hulk in trailers before the film’s release. Marvel Studios’ highly anticipated installment, Captain America: Brave New World, hit United States theaters in February and later arrived on Disney+, bringing major fan attention to this casting and plot detail.
In Captain America: Brave New World, Anthony Mackie stars once again as Sam Wilson, stepping into the shoes of Captain America. Harrison Ford joins the cast as Thaddeus ‘Thunderbolt’ Ross, portraying the much-hyped Red Hulk. The marketing campaign and early trailers confirmed Ford’s transformation into Red Hulk, despite the fact that the reveal does not take place until the closing moments of the film. This choice drew considerable comment from fans since the transformation is meant to be a significant plot twist in the story.
Director Julius Onah Discusses the Decision Behind the Reveal
Julius Onah shared his thoughts on the matter in a conversation with Empire Magazine, expressing that the studio never considered keeping the Red Hulk transformation a secret in the promotional material. He explained the challenges faced when dealing with a franchise as popular as the Marvel Cinematic Universe and its very dedicated fanbase. Onah noted,
“When you’re making a movie like this, an announcement goes out that Harrison Ford is going to play Thaddeus Ross, and you have a fandom as massive and as passionate as the MCU fandom is, you’re toast at that point, you know? In a perfect-case scenario, it would have been awesome [if ] that [had been] an in-theatre surprise, but I think it would have been very difficult. Somewhere along the way, a toy would have been found, or somebody would have leaked a trailer. It’s just so hard to keep anything secret in today’s day and age.”

Onah’s comments capture the complicated nature of modern movie marketing, where leaks and merchandise can easily spoil major surprises. As soon as Ford’s casting as Thaddeus Ross was made public, theories and expectations grew rapidly, making secrecy a nearly impossible task given how storytelling and fan culture have changed around Marvel films.
The Full Ensemble Joins the Spotlight
Joining Mackie and Ford are a wide array of established and new faces in the Marvel Cinematic Universe. Danny Ramirez appears as Joaquin Torres, better known as Falcon, with Shira Haas taking on the role of Ruth Bat-Seraph. Carl Lumbly features as Isaiah Bradley, and Xosha Roquemore portrays Leila Taylor. The cast is rounded out by Giancarlo Esposito as Seth Voelker, Liv Tyler as Betty Ross, and Tim Blake Nelson as Samuel Sterns, bringing both continuity and fresh storylines to the sequel.
Each actor, from Anthony Mackie’s returning Captain America to newcomers like Shira Haas, plays a unique role in the ensemble narrative, supporting the main arc that leads up to the transformation of Thaddeus Ross into Red Hulk. With this major reveal now widely known, much of the movie’s suspense centered around how, rather than if, Ford’s character would undergo this transformation.
Implications for Future Marvel Films
The public reveal of Harrison Ford’s Red Hulk transformation highlights ongoing challenges faced by Hollywood studios in maintaining secrecy around blockbuster plots. For Marvel Studios and upcoming projects, the expectations of fans and the realities of large-scale merchandising and digital leaks seem likely to shape how future surprises are unveiled. Captain America 4’s promotional campaign serves as a case study in balancing fan enthusiasm, actor announcements, and storytelling secrets in a media landscape where spoilers are hard to prevent.
Captain America: Brave New World is currently streaming on Disney+, with its cast and creative choices continuing to spark discussions within the MCU fandom and beyond.
