Marvel’s ‘Thunderbolts’: The Sentry’s Dark Persona, The Void, Transforms into an Alternate Realm for Characters to Explore

Marvel’s ‘Thunderbolts‘ will begin filming in January 2024. The film is scheduled to be released in theaters on July 25, 2025.

Who is playing Sentry in the MCU’s ‘Thunderbolts’?

Steven Yeun is set to play Sentry in the MCU and will appear in ‘Thunderbolts.’ In the film, The Void, associated with Robert “Bob” Reynolds‘ negative aspects, transforms into a realm that characters can enter in the third act. This deviation from Sentry’s character aligns with inspiration from the comics.

Who is The Void in Marvel Comics?

In Marvel Comics, The Void is the dark and destructive side of the superhero Sentry. It represents the negative aspects of Sentry’s powers and personality, emerging when he loses control or is influenced by external forces. The struggle between Sentry and The Void is a key element in many Marvel storylines, adding psychological and internal conflict to the character’s story.

It was already reported that in the MCU, Yeun’s Sentry joins the Thunderbolts team in the first two acts, but an unexpected event tears him away from them. In the film, Sentry joins the Thunderbolts but turns against them due to an incident, and he’s confirmed to be one of the film’s villains. Director Jake Schreier has revealed that the Thunderbolts will consist of individuals who share a common history of past trauma.

‘Thunderbolts’ stars Sebastian Stan as Bucky Barnes/Winter Soldier, Florence Pugh as Yelena Belova, Wyatt Russell as John Walker/U.S. Agent, Olga Kurylenko as Antonia Dreykov/Taskmaster, David Harbour as Alexei Shostakov/Red Guardian, Hannah John-Kamen as Ava Starr/Ghost, Julia Louis-Dreyfus as Contessa Valentina Allegra de Fontaine, Harrison Ford as President Thaddeus Ross, Sadie Sink as Songbird, Ayo Edebiri in an unspecified role, and Yeun.

Directed by Schreier from a script written by Lee Sung Jin and Eric Pearson. Produced by Kevin Feige, Brian Chapek, Matthew Jenkins, and David J. Grant.

Thunderbolts will hit theaters on July 25, 2025.
