Marvel Studios has officially given fans a deeper look into Thunderbolts with an exclusive behind-the-scenes clip that shines a spotlight on Sentry one of the most mysterious and powerful characters entering the Marvel Cinematic Universe (MCU). The Thunderbolts Sentry BTS clip not only reveals the incredible transformation of Lewis Pullman into the conflicted hero Bob Reynolds (aka Sentry), but also teases the raw power of his dark alter ego, the Void.
Lewis Pullman’s Journey Into Sentry’s Complex World
In this newly released featurette, Lewis Pullman opens up about how he approached the role of Sentry, a character unfamiliar to many outside comic circles. “I hadn’t heard of Sentry before this,” Pullman admits, “but the more I read, the more I felt connected to Bob.”
Marvel fans will know that Sentry isn’t your typical superhero he’s a man struggling with duality. On one hand, he’s the golden guardian of good, and on the other, he harbors the Void, a dark and dangerous force threatening to consume everything.
Playing Three Roles in One: Bob, Sentry, and the Void
Director Jake Schreier describes the role as “playing three people in one,” a task he credits Pullman with handling masterfully. According to Schreier, weekly creative meetings were held during production to decide when each version of the character Bob, Sentry, or Void would appear.
Florence Pugh, who reprises her role as Yelena Belova, praises Pullman’s performance: “I couldn’t quite imagine where Bob was going to go in this, but what Lewis has done is really hard work. He did a masterful job.”
Thunderbolts Redefines Marvel’s Heroes
Though the film is titled Thunderbolts (with an asterisk), the asterisk was later revealed to be a placeholder a sign of something more. By the end of the movie, Marvel fans are hit with a huge twist: the ragtag team is officially rebranded as the New Avengers, hinting at a new direction for the MCU’s future.
Sentry’s Entrance and the Chaos That Follows
The BTS clip also reveals how Bob makes his entrance right after an epic superhero brawl. His arrival isn’t met with celebration; it’s met with confusion and fear. As Pullman explains, “The first act is trying to figure out if [Bob] is part of it, how he can help. But every time he tries, it always makes things worse.”
This perfectly captures Sentry’s tragic essence a hero who wants to help but often causes more harm than good, not because of ill intent, but because of the instability caused by the Void.
A Game-Changing Character for the MCU
This Thunderbolts Sentry BTS clip isn’t just a behind-the-scenes treat it’s a glimpse into the MCU’s deeper, darker evolution. Pullman’s portrayal of Sentry/Bob/Void adds psychological weight to the film, pushing Marvel’s storytelling into more complex emotional territory.
The featurette makes one thing clear: Sentry isn’t just another super-powered addition. He’s a ticking time bomb with a heart someone the audience might empathize with just as much as they fear.
Final Thoughts
With a mix of emotional vulnerability and uncontrollable power, Lewis Pullman’s Sentry could become one of the MCU’s most unforgettable characters. If this BTS clip is anything to go by, Thunderbolts is shaping up to be more than just another superhero team-up it’s a bold reset, with darker tones and layered characters leading the charge.
