Thunderbolts* Cast (2025)
Marvel Studios | Action, Superhero, Drama | 127 min | Directed by Jake Schreier
Thunderbolts* assembles a ragtag group of morally compromised, government-trained operatives — each with a traumatic past and no great love for one another — and forces them to work together when they discover they have been set up to be eliminated by the very person who recruited them. The team includes Black Widow Yelena Belova, the reformed assassin Bucky Barnes, the Russian super-soldier Red Guardian, the disgraced U.S. Agent, the quantum-powered Ghost, and the lethal Taskmaster. When a mysterious and enormously powerful figure named Bob enters the picture, the stakes escalate far beyond anything the team is equipped to handle alone.
The Thunderbolts* cast is a carefully assembled ensemble of MCU supporting players who have each been seeded across multiple films and Disney+ series over the preceding years. Florence Pugh leads the group as Yelena Belova, whose arc since Black Widow (2021) has made her one of the MCU's most compelling new characters. Opposite her, Sebastian Stan's Bucky Barnes provides the film's most experienced Avenger, while the comedic chemistry between David Harbour's Red Guardian and the rest of the team gives the film much of its heart. The casting of Lewis Pullman as the Sentry — one of Marvel Comics' most powerful and psychologically complex figures — is the film's most consequential creative choice, introducing a character whose presence rewrites the rules of what the MCU's heroes can handle.
Main Cast
Florence Pugh
Yelena Belova
A highly trained Black Widow operative and Natasha Romanoff's surrogate sister, who reluctantly becomes the emotional center of this unlikely team.
Sebastian Stan
Bucky Barnes / Winter Soldier
Steve Rogers's best friend and former Soviet-programmed assassin, now trying to forge an identity beyond his traumatic past while navigating a new kind of team dynamic.
David Harbour
Alexei Shostakov / Red Guardian
The Soviet Union's answer to Captain America — a super-soldier of enormous physical strength and even more enormous ego — who provides much of the film's comic relief while revealing unexpected emotional depth.
Wyatt Russell
John Walker / U.S. Agent
The disgraced Super Soldier-serum-enhanced former Captain America replacement, now operating as U.S. Agent under Valentina's employ and struggling with his violent impulses.
Hannah John-Kamen
Ava Starr / Ghost
A woman whose molecular instability allows her to phase through solid matter, a condition she has lived with since childhood and which shaped her into a lethal government weapon.
Olga Kurylenko
Antonia Dreykov / Taskmaster
The daughter of the Red Room's director, whose brain was reprogrammed to give her perfect photographic combat reflexes, making her capable of instantly replicating any fighting style she observes.
Julia Louis-Dreyfus
Valentina Allegra de Fontaine
The manipulative intelligence operative and Director of the CIA who assembled the Thunderbolts for her own purposes, and whose agenda proves far more dangerous than any of them suspected.
Lewis Pullman
Bob / Sentry
A seemingly ordinary, deeply troubled man named Bob who is revealed to be the Sentry — a superhuman of near-godlike power whose psychological fragility makes him as dangerous as any villain the team has faced.
Geraldine Viswanathan
Mel
A key supporting figure who becomes entangled with the Thunderbolts and brings a grounded, civilian perspective to the film's increasingly extraordinary events.

About the Thunderbolts* Cast
What makes the Thunderbolts* cast distinctive within the MCU is that virtually every member was introduced as either a villain, a morally compromised government operative, or a deeply flawed anti-hero. None of them are straightforward protagonists in the traditional Marvel sense. Florence Pugh's Yelena Belova is perhaps the closest — her grief over Natasha Romanoff's death and her dry, sardonic humor have made her one of the franchise's most beloved new additions since Black Widow — but even she is an assassin navigating serious psychological damage. The casting of David Harbour and Wyatt Russell gives the ensemble a strong comedic and dramatic range, while Sebastian Stan's Bucky Barnes provides the team's most direct link to the Avengers era.
The breakout element of the ensemble is Lewis Pullman as Bob/Sentry. Pullman, son of actor Bill Pullman and previously seen in Top Gun: Maverick (2022) and the film Catch, brings an unexpected vulnerability to a character who could easily have been played as simply a power fantasy. The Sentry is one of Marvel Comics' most psychologically rich figures — a Superman-level hero who suffers from severe mental illness, whose inner demon (the Void) threatens to destroy everything around him. Casting a relatively young, physically slender actor rather than a conventionally built action hero was a deliberate creative choice that emphasizes the character's fractured interior life over his raw physical power. The asterisk in the film's official title relates directly to this character's significance to the story's conclusion.
