Earlier this year, it was announced that Steven Yeun was set to join Marvel Studios’ “Thunderbolts.” At the time, Steven’s specific role was not confirmed but sources told Deadline that his role “is not only significant to this film but could also play a role going forward in future films of the Marvel Cinematic Universe.”

After this casting announcement, fans speculated that Steven may play the role of Sentry, a Marvel character who is believed to be the villain of the movie.

On November 16, Robert Kirkman (creator of “Invincible” and co-creator of “The Walking Dead”) appeared on David Finch’s (comic artist) YouTube show and confirmed that Steven is playing the role of Sentry.

On the show, Kirkman said, “My good friend Steven Yeun is playing the Sentry in a movie. He called me, he went in for a costume fitting… I hope I’m not... I don’t think this is a spoiler, or anything that will get anybody in trouble. I don’t know, maybe, we’ll see. I don’t care, I don’t work for Marvel, what are they gonna do to me? He called me and he said, ‘Uh, I just came back from a costume fitting for the Sentry. I guess I only do superheroes that are yellow and blue.' He said he was at the costume fitting and was like ‘Aw crap, I forgot Invincible was yellow and blue!’”

As of this writing, Marvel Studios has not confirmed Steven’s specific role.

“Thunderbolts” is scheduled to arrive in theaters on July 25, 2025. David Harbour, Hannah John-Kamen, Julia Louis-Dreyfus, Sebastian Stan, Wyatt Russell, Olga Kurylenko and Florence Pugh also star in the film.
