Steven Yeun Leaves MCU Door Open Despite Thunderbolts Exit

Steven Yeun remains open to working with Marvel Studios despite his recent departure from the Thunderbolts* project due to scheduling conflicts. Known for his roles in The Walking Dead and Invincible, Yeun still holds a high opinion of director Jake Schreier and expressed willingness to rejoin the Marvel Cinematic Universe if future opportunities arise.

“I love Jake, Jake Schreier, incredible human director. I never say never. I’m around.”

Yeun’s Career Path From Glenn to Mark Grayson and MCU Prospects

Yeun first gained widespread acclaim as Glenn on The Walking Dead before voicing Mark Grayson in the animated series Invincible. In 2023, he was quietly attached to Marvel’s Thunderbolts*, reuniting with Schreier who had directed episodes of Beef starring Yeun. Their collaboration influenced the film’s marketing approach, opting for a moodier, indie-inspired aesthetic rather than typical MCU spectacle.

Behind Yeun’s Exit from Thunderbolts*

The precise details of Yeun’s role in Thunderbolts* were never officially revealed, prompting fans to speculate that he might have played the Sentry, a complex and incredibly powerful anti-hero. However, the 2023 writers’ and actors’ strikes caused production delays. When filming resumed, Yeun’s schedule no longer aligned with the new dates, forcing him to withdraw from the project. Lewis Pullman was eventually cast as Sentry, also known as ‘Bob’. This change stemmed purely from scheduling issues, not creative differences, which explains Yeun’s continued positive comments about Schreier and his open attitude toward future Marvel roles.

Gillian Jacobs Shares Her Own Marvel Aspirations

Yeun’s Invincible co-star Gillian Jacobs has also expressed interest in joining Marvel projects. She enthusiastically proposed a concept centered on the character Dakota North, a lesser-known Marvel comic, suggesting it would make a compelling TV show. Jacobs is willing to contribute on screen or behind the scenes, admiring the sharp storytelling and stylish tone of that world.

“I actually have a pitch. Do you know this comic, Dakota North? It was a short-run Marvel comic. I think that would make a great TV show.”

Invincible Returns March 18 With Yeun Leading Again

Although Yeun’s MCU future remains uncertain, fans can look forward to his return as Mark Grayson in Invincible season 4 on Prime Video beginning March 18. He will once again star alongside Gillian Jacobs, Sandra Oh, and J.K. Simmons. The new season explores how the world struggles to recover from a recent global disaster, with Mark facing the heavy burden of protecting his home and loved ones while confronting a new, formidable threat that could transform the future of humanity.
