Thunderbolts: An Updated Cast List For The Marvel Movie, Including Sebastian Stan And Florence Pugh

For years now, we’ve been following along with the Avengers and the Guardians of the Galaxy in the Marvel Cinematic Universe, and in 2025, a new team will make its debut in this superhero franchise. In June 2022, it was reported that a Thunderbolts movie was in development, and just like how the team is traditionally depicted in the comics, the membership will be made up of anti-heroes and reformed supervillains. Paper Towns’ Jake Schreier is directing the upcoming Marvel movie, and Lee Sung Jin was rewriting the script as of March 2023.

At San Diego Comic-Con 2022, Marvel Studios confirmed that Thunderbolts was on the way, and just a couple months later at D23, the team’s lineup was unveiled to the public. We’re still in the dark about what kind of threat the MCU’s Thunderbolts will deal with, but while we wait for that information to arrive, let’s go over the actors who have come aboard this feature, most of whom, including Sebastian Stan and Florence Pugh, we’ve already spent time with in the MCU.

Sebastian Stan

Sebastian Stan has been part of the MCU longer than anyone else on this list, first appearing as Bucky Barnes in Captain America: The First Avenger. Originally thought to have perished in that movie, Bucky was brought back into play in Captain America: The Winter Soldier as a brainwashed HYDRA assassin. Fortunately, by the end of that movie, Bucky managed to break free from the terrorist organization, though he still had to deal with HYDRA’s lingering influence on his mind in Captain America: Civil War. Stan then reprised Bucky in Avengers: Infinity War and Avengers: Endgame, and in 2021, he co-starred with Anthony Mackie in The Falcon and the Winter Soldier.

When we left off with Bucky Barnes in that series, he’d finally made amends with everyone he’d hurt as the Winter Soldier, then headed to Louisiana to join Sam Wilson and his community for a celebratory cookout. He’d finally reached a good point in his life after decades of hardship, but the time has come for him to put his unique set of skills back to use. From what little has been shown and revealed so far, it’s possible that Bucky will be leading the Thunderbolts in the field.

Florence Pugh

Natasha Romanoff is no longer with us in the MCU, but the Black Widow mantle is now chiefly carried on through Florence Pugh’s Yelena Belova. We met Yelena during the Black Widow movie, which was set in between Captain America: Civil War and Avengers: Infinity War. The adoptive sisters went on one last adventure that saw them freeing the other Black Widow agents, as well as Taskmaster (more on her later) from the Red Room’s influence. Unfortunately, that was the last time Natasha and Yelena would see each other, with Black Widow’s post-credits scene showing Yelena visiting Natasha’s grave.

In that same scene, Valentina Allegra de Fontaine assigned Yelena to kill Clint Barton, a.k.a. Hawkeye, whom she blamed for Natasha’s death. Yelena attempted to carry out this task during the Hawkeye series and formed a… unique relationship with Kate Bishop along the way, but by that show’s finale, Clint persuaded her to drop this mission of vengeance. So Yelena didn’t carry out what Valentina expected of her, but these two will be working together again during Thunderbolts, which brings us to the next section.

Julia Louis-Dreyfus

Nick Fury is still active in the MCU, but Julia Louis-Dreyfus’ Valentina Allegra de Fontaine has been giving off the same kind of vibes the one-eyed spy did in the MCU’s Phase 1. Prior to her appearance in Black Widow, Valentina first appeared in The Falcon and the Winter Soldier, when she approached John Walker after he’d been discharged from the military and stripped of the Captain America mantle. Valentina thought John made the right call taking the Super Solider Serum and murdering a Flag Smasher, and by the Falcon and the Winter Soldier finale, she’d set him up as U.S. Agent.

Then in November 2022, Valentina resurfaced in Black Panther: Wakanda Forever as the new head of the CIA, and we also learned that she and Everett K. Ross used to be married. Despite that connection, she didn’t hesitate to arrest Everett when she learned he shared classified intelligence with the Wakandans. Now there’s Thunderbolts on the horizon, and just like Nick Fury did with the Avengers, it’s looking like Valentina will be responsible for this team’s creation. However, this is a woman who looks like she’s willing to step over certain lines that Fury would never cross.

Wyatt Russell

Although Sam Wilson accepted the elderly Steve Rogers’ shield at the end of Avengers: Endgame, when The Falcon and the Winter Soldier rolled around, he was hesitant to actually become the new Captain America. As such, he gave the shield to the U.S. government, and they in turned appoint John Walker to carry on as Steve’s successor. However, the pressure of being the patriotic superhero quickly weighed on John, and it also soon became clear that he had anger issues and a massive ego. This all came to a head when he injected himself with the Super Soldier Serum, which amplified these qualities and led to him brutally murdering one of the Flag Smashers.

As already mentioned, John was then relieved of duty, and it wasn’t long after that Sam Wilson finally decide to suit up as Captain America. But now John is walking down a new path as U.S. Agent, and because Valetina Allegra de Fontaine is in charge of the CIA, then he’s basically still working for the U.S. government, just in a different capacity. I have a feeling that of the Thunderbolts members, U.S. Agent will be the one to potentially go too far during a mission given that he’s on the more unstable side.

David Harbour

Alexei Shostakov, a.k.a. Red Guardian, was the father figure in the family unit that Natasha Romanoff and Yelena Belova were in as kids, with Melina Vostokoff being the mother figure. However, sometime after their mission in the United States ended, David Harbour’s character was thrown into prison, and had Natasha and Yelena not freed him, he likely would have spent the rest of his life incarcerated. Luckily that wasn’t to be, and after putting his Red Guardian suit back on, Alexei teamed up with Natasha, Yelena and Melina to take down Dreykov and the Red Room.

Alexei was last seen leaving to parts unknown with Melina, Yelena, the remaining Black Widows and Taskmaster as Black Widow’s main story concluded, so when we reunite with him in Thunderbolts, over half a decade will have passed in the MCU timeline. Hopefully we learn a little bit of what Red Guardian has been up to, but with Yelena also on the team, it’s probably a safe bet that she’s responsible for his recruitment.

Hannah John-Kamen as Ava Starr, a.k.a. Ghost, in Ant-Man and the Wasp

Hannah John-Kamen

So far the only Thunderbolts character who’s been announced with actual superpowers is Ava Starr, a.k.a. Ghost, who Hannah John-Kamen first played in Ant-Man and the Wasp. As a result of being caught in an accident in her father’s lab as a child that killed both of her parents, Ava gained the power of intangibility. The problem was that her body was in a constant state of "molecular disequilibrium,” requiring her to wear a special suit to control her ability to phase through solid matter. Ava agreed to work for S.H.I.E.L.D. in exchange for a cure for her condition, but when she learned that S.H.I.E.L.D. was controlled by HYDRA and had no actual intention of helping her, she fled with Bill Foster, a scientist colleague of her father’s who sincerely offered to help her.

During Ant-Man and the Wasp, Ava and Bill wanted to harness the quantum energy that Janet van Dyne was filled with to devise their cure, but Hank Pym believed this would kill his wife. So Ghost proved to be a major nuisance throughout that Marvel movie, but Janet eventually willingly gave her some quantum energy to temporarily stabilize her. Ava and Bill then went into hiding, and while Scott Lang, Janet, Hank and Hope van Dyne had planned to deliver more quantum energy to Ava, Scott ended up being trapped in the Quantum Realm while retrieving that energy, and the latter three were among the people Thanos turned to dust. But evidently Ava’s still ok all the these years later if she’s participating in Thunderbolts, though whether she’s been permanently cured of her condition by this point or not is unclear.

Olga Kurylenko

Taskmaster’s identity was kept secret during the marketing of Black Widow, but within the movie itself, we learned it was Olga Kurylenko’s Antonia Dreykov who was under that mask. Thought to have been killed by Natasha Romanoff when she was trying to assassinate Antonia’s father, she was actually gravely injured and disfigured. Dreykov inserted a chip into his daughter to relieve her of her agonizing pain, but this also allowed her to completely control her. That, combined with Antonia’s natural ability to mimic any physical action she sees, resulted in Dreykov turning the girl turning the girl into Taskmaster, a brainwashed assassin who carried out the Red Room’s directives. 

Antonia spent most of Black Widow essentially as a blunt instrument for her father’s schemes, but Natasha Romanoff was eventually able to snap her free of the mind control using the final vial of Red Dust. With her direction in life now uncertain, Antonia left with the surviving Black Widows, Yelena, Alexei and Melina before the authorities arrived. Like with Alexei, it would be nice to learn what’s been up to in between Black Widow and Thunderbolts, but much like Bucky did with his Winter Solider identity, at least she’s now acting as a force for good as Taskmaster.

Harrison Ford

Following the passing of William Hurt, Harrison Ford is taking over the role of Thaddeus “Thunderbolt” Ross in the MCU. As far as that character’s history in this franchise goes, although we last saw him hunting down Natasha Romanoff in Black Widow, chronologically within the MCU timeline, he was most recently seen attending Tony Stark’s funeral. Since it was revealed in She-Hulk: Attorney at Law that the Sokovia Accords have been overturned, Ross now finds himself back in a world where superheroes are free to operate without any government supervision.

Harrison Ford will first appear as Thunderbolt Ross in Captain America: Brave New World, and he’ll be back for Thunderbolts a few months later. Along with it being unclear if the team is named after him, which it most certainly is not in the comics, it also hasn’t been clarified if he’ll be allied with the Thunderbolts or somehow be an adversary to them, though the fact that he's President of the United States in Brave New World would suggest the former is more likely. If it does end up being the latter though, that definitely strengthens the speculation that the MCU’s Ross will turn into Red Hulk.

Lewis Pullman

At the start of January 2024, Beef star Steven Yeun dropped out of Thunderbolts, with the actor later confirming it was due to scheduling issues. A few weeks later, Top Gun: Maverick's Lewis Pullman was reported to be lined up as Yeun's replacement. Assuming a deal has been worked out, while we don't officially know what Pullman's role will be, back when Yeun was still attached, Invincible creator Robert Kirkman let slip that the Mark Grayson voice actor had done a costume fitting for Sentry. If this is indeed true, then we can count on Pullman, who's also leading the Salem's Lot remake, to be playing one of Marvel's most powerful characters.

Geraldine Viswanathan

At the end of January 2024, Thunderbolts was hit with another casting shakeup. Like Steven Yeun, The Bear's Ayo Edebiri had to stepped away from the movie due to scheduling issues, and Geraldine Viswanathan was cast in her place. Reporter Jeff Sneider claimed on his The InSneider newsletter that Viswanathan will play Valentina Allegra de Fontaine's assistant. For those wondering where you might have seen the actress before, her major credits include Blockers, The Broken Hearts Gallery, The Beanie Bubble, Drive-Away Dolls and Miracle Workers.

Laurence Fishburne

When Ava Starr’s parents died, Bill Foster became her surrogate father. In addition to having worked Elias Starr at S.H.I.E.L.D., Foster was also once Hank Pym’s assistant on Project Goliath, allowing him to try growing his body to enormous heights on several occasions. As mentioned earlier, Bill wanted to sincerely help Ava with her condition, and after Janet van Dyne stabilized the woman towards the end of Ant-Man and the Wasp, she and Bill went on the run. Laurence Fishburne is now reportedly reprising Bill in Thunderbolts, which begs the question of if the two of them have had their records cleared, or if Bill will still have to keep a low profile once Ava starts working with the title team. Like the next person on this list, Fishburne also voiced an alternate Bill in the animated series What If… ?.

Rachel Weisz

Remember when I mentioned Melina Vostokoff earlier? Like Alexei Shostakov, Rachel Weisz’s character reentered the lives of Natasha Romanoff and Yelena Belova in Black Widow. Because Yelena was shown to be doing her own thing in Hawkeye, I imagine that Melina has been spending the years between Black Widow and Thunderbolts by Alexei’s side, as it clearly looked like they were ready to resume their romantic relationship in the former movie. Although Alexei and Yelena will be part of the Thunderbolts team, I’m curious what the rationale will be for Melina not joining. That’s assuming, of course, that Valentina hasn’t already recruited her for a
