Marvel Studios’ search for its “evil Superman” is over if a new round of rumors and reports is to be believed. As work on Thunderbolts progresses ahead of its scheduled June production start, it appears that The Walking Dead star Steven Yeun has landed the role of Robert Reynolds/Sentry.
Rumors of the involvement of the Sentry in the plot of Thunderbolts have swirled since late Fall of 2022 when a casting call for an “evil Superman” circulated online. After sorting through a few of Marvel’s Superman analogs, Sentry rose to the top of the list of possible choices and additional information from reliable insiders has continued to build the case that he’ll make his MCU debut in the film. Now a slew of reports, including one from The Illuminerdi, all indicate that the 39-year-old Yeun has landed the part, which will make him a key player in the MCU beyond the events of 2024’s Thunderbolts.
Though Yeun is most well known (and beloved by fans) for his long-running role as Glenn on AMC’s The Walking Dead, should he have landed the role of Sentry it won’t be his first rodeo as a nigh-omnipotent and indestructible hero. Yeun has served as the voice of Mark Grayson, the Viltrumite-human hybrid hero known as Invincible, for 2 seasons of the animated Amazon Prime series Invincible. For all their similarities in terms of powers, however, Sentry and Invincible are far from the same character and stepping into the role of Sentry would provide Yeun an opportunity to explore a character with a much, much darker side. In the comics, that darker side is, in part, due to an entity known as The Void, and that entity is rumored to appear in Thunderbolts as a key part of Sentry’s character arc.
