In 2025, the Marvel Cinematic Universe introduced a standout new character: Sentry, portrayed by Lewis Pullman in Thunderbolts. The MCU version of Sentry differed from the comic books, cleverly skipping the complex backstory of a hero with long-forgotten origins. Instead, the films presented him as a manipulated hero forced to fight alongside the Thunderbolts, until his darker side, known as the Void, emerged as a new threat. Now back in control, Sentry has a promising future within the MCU. Interestingly, Lewis Pullman wasn’t the first choice for the role – Steven Yeun was originally considered, and his take on the character could have been very different.
Steven Yeun, known for voicing the main character in Invincible, was initially cast as the Sentry in the upcoming Thunderbolts movie. This would have reunited him with director Jake Schreier, who previously directed him in Beef. Unfortunately, scheduling conflicts led to a change in casting. However, Yeun told MovieWeb he’s not upset about it, genuinely enjoys the Thunderbolts project, and remains open to joining the Marvel Cinematic Universe in the future. He said, “I did see it. I love Jake, Jake Schreier, incredible human director… I did see it and I never say never. I’m around.”
Steven Yeun Could Have An MCU Future After Invincible
It’s difficult to imagine Steven Yeun as the Sentry, especially considering how well Bill Pullman played the character in Thunderbolts. Yeun is a talented actor – proven by his work in shows like The Walking Dead and Beef – but Pullman brought a uniquely damaged and uncomfortable energy to the role. While Yeun would be a great addition to the Marvel Cinematic Universe, he’d be better suited for a very different kind of character.
The Marvel Cinematic Universe has offered important roles to Asian actors, particularly with the Shang-Chi films. Steven Yeun is proud of his heritage, and many consider his most impactful work to be the film Minari, where he made history as the first East Asian-American to be nominated for the Best Actor Oscar. In Minari, he portrayed a father who moved his family to a farm in rural Arkansas in the 1980s, hoping to supply produce to Dallas. It was a truly exceptional performance and stands out as one of the best films of the past ten years.
Marvel succeeded with Shang-Chi and the Legend of the Ten Rings by prioritizing Asian representation – casting primarily Asian actors like Simu Liu, hiring an Asian director (Destin Daniel Cretton) and writers (Cretton and David Callaham), and allowing a respectful and accurate adaptation of the story. Steven Yeun would be a fantastic addition to a future Shang-Chi film, and it’s surprising he hasn’t been cast yet. Regardless, his talent—as demonstrated in Invincible and other roles—deserves a significant opportunity within the Marvel Cinematic Universe.
