Hannah John-Kamen Opens Up About Her Intense Vision for Ghost in 'Thunderbolts*'

At the star-studded Los Angeles premiere of Thunderbolts*, Hannah John-Kamen sat down with The Hollywood Reporter to pull back the curtain on her portrayal of the elusive Ghost. Known for her ability to vanish into roles—both literally and figuratively—the actress described the precise emotional and physical layers she wanted to inject into the character. While official transcripts are scarce, John-Kamen’s candid chat (as documented in Screenshot (550).png) offered a rare glimpse into how she approached one of Marvel’s most enigmatic antiheroes.

A Return to the MCU with New Depth

John-Kamen first introduced the world to Ghost in Ant-Man and the Wasp (2018), where the character was a complex adversary struggling with chronic pain and a desperate need for quantum energy to survive. That version of Ghost was a traumatic figure—scientist Ava Starr—whose phasing abilities came at a terrible cost. Now, years later, the actress is back to explore what happens when a former villain must team up with other morally gray misfits. For John-Kamen, this wasn't just a reprise; it was a chance to dig deeper.

What She Wanted to Bring to the Role

According to the interview, John-Kamen focused on uncovering Ghost's humanity beneath the cold, phasing exterior. She spoke about wanting to highlight the character's vulnerability while still retaining that dangerous edge that makes Ghost unpredictable. The actress detailed how she studied the psychological toll of isolation—a key theme for a character who can literally disappear from the world. By grounding Ghost in real emotional pain, John-Kamen aimed to make every phasing moment more than a visual effect; it had to tell a story of loss and survival.

The Evolution of Ghost: From Villain to Unlikely Hero

Thunderbolts* repositions Ghost within a squad of government-manipulated operatives, including Yelena Belova, Bucky Barnes, and Red Guardian. The asterisk in the title hints at a twist—something deeper about the team's true purpose. John-Kamen’s Ghost is no longer a solo agent driven by vengeance; she must now navigate alliances and betrayal. The actress noted that the dynamic allowed her to explore new shades of the character: trust, camaraderie, and even reluctant humor. In the premiere chat, she emphasized that Ghost’s arc in this film is about learning to exist in a group without losing her edge.

Behind the Scenes at the Premiere

The red carpet at the TCL Chinese Theatre was electric. John-Kamen arrived in a shimmering custom gown that played with transparency—a subtle nod to her character's power. While discussing her process, she revealed that she collaborated closely with the directors Jake Schreier and writers to ensure Ghost’s phasing effects carried emotional weight. Every time Ava flickers out of sight, it's not just a power display; it's a visual representation of her internal conflict. This level of detail, she explained in the Screenshot (550).png transcript, was essential to making Ghost feel three-dimensional rather than a plot device.

Hannah John-Kamen: A Rising Star's Journey

Born in Anlaby, England, John-Kamen has quietly become one of the most versatile actresses in genre entertainment. From Game of Thrones to Ready Player One, she has a knack for playing characters who exist on the fringe. Her performance as Dutch in the Netflix series Killjoys proved she could carry a long-running sci-fi saga, while her turn in Resident Evil: Welcome to Raccoon City showed she could anchor a horror hit. But it's her work as Ghost that has become her defining Marvel role.

Why Ghost Resonates with Audiences

• Relatable Pain: Unlike many superheroes, Ghost's powers are a curse. John-Kamen’s portrayal of Ava’s constant physical suffering makes her sympathetic despite her villainous actions.
• Moral Ambiguity: She operates in shades of gray—neither hero nor villain, which is perfect for the Thunderbolts’ premise.
• Visual Spectacle: Her phasing abilities are among the most visually unique in the MCU, and John-Kamen’s commitment to selling those moments with her body language elevates the effects.

In the interview, John-Kamen cited the fan response to Ghost in Ant-Man and the Wasp as a driving force for her return. She wanted to honor the audience's investment by diving even deeper into Ava's psyche. The result, judging by early buzz from the premiere, is one of the most layered performances in Thunderbolts*.

The Thunderbolts* Dynamic: A New Kind of Team

The film assembles a rogues' gallery of MCU characters: Florence Pugh's Yelena, Sebastian Stan's Bucky, David Harbour's Red Guardian, Wyatt Russell's John Walker, Olga Kurylenko's Taskmaster, and Julia Louis-Dreyfus' Valentina Allegra de Fontaine. John-Kamen's Ghost is the wild card—the one whose loyalty is most questionable. She mentioned that on set, the cast developed a camaraderie that mirrored the film's theme of reluctant teamwork. There was a lot of improvisation, especially in scenes where Ghost phases in and out of conversations, literally appearing and disappearing. That spontaneity, she noted, kept everyone on their toes and added a layer of unpredictability to the performances.

Staying True to the Source Material

John-Kamen is careful not to deviate from the established comics canon where Ghost is often a tech-based villain with a shifting identity. However, she and the writers chose to focus on Ava Starr’s personal tragedy—the death of her father, the accident that gave her powers—rather than making Ghost a pure antagonist. By highlighting the human cost of superheroics, John-Kamen ensures that Ghost isn't just a cool power set; she is a soul in turmoil. The actress admitted that preparing for this role required revisiting the emotional beats of Ant-Man and the Wasp and amplifying them for a larger stage.

What’s Next for Ghost?

While John-Kamen remained tight-lipped about future appearances, she hinted that Thunderbolts* leaves Ghost’s fate open-ended. The film’s post-credits scene—which she playfully refused to spoil—apparently sets up a major direction for the character. Given the buzz around the premiere, fans are already speculating about Ghost's role in upcoming Phase 5 projects. For now, John-Kamen is just proud to have brought a new dimension to a fan favorite. She concluded the THR chat by thanking the audience for embracing Ghost's complexity, noting that the best characters are the ones who grow.

As the credits rolled on the premiere, it was clear that John-Kamen’s vision for Ghost had paid off. The character is no longer just a one-off villain; she is a key player in Marvel’s expanding galaxy of antiheroes. And with her powerful, nuanced performance, Hannah John-Kamen has proven that even a ghost can leave a lasting impression.
