Billie Boullet is a 21-year-old British actress whose career has moved from a small CBBC role to a Netflix lead in just six years. She first drew attention as Anne Frank in the Disney+ and National Geographic miniseries “A Small Light,” a performance that earned her a Critics’ Choice Award nomination at 18. In 2026, she took her biggest step yet, starring as Poe Rayburn opposite Yahya Abdul-Mateen II in Netflix’s “Man on Fire,” a role that has pushed her from a promising young talent into a genuine rising star.
Who Is Billie Boullet
Billie Boullet is a British actress best known for playing Anne Frank in the Disney+ and National Geographic miniseries “A Small Light,” a role that earned her a Critics’ Choice Award nomination at just 18. In 2026, she stepped into a much bigger spotlight as Poe Rayburn, the teenage lead opposite Yahya Abdul-Mateen II in Netflix’s “Man on Fire.”
Her career has moved fast for someone who only started auditioning seriously a few years ago. From a supporting part on a CBBC children’s show to a lead role on one of Netflix’s biggest 2026 releases, Boullet’s trajectory says more about her range than any single credit does.

Early Life Between Paris and London
Boullet was born in the London borough of Brent in April 2005. Her family moved to Paris while she was still a baby, and she spent much of her early childhood there before the household returned to England in 2014. That back and forth between two countries gave her an early exposure to the French language and culture that she has carried into adulthood.
She grew up in a Jewish family, and that background later became part of what drew her toward playing Anne Frank. Boullet has described building her performance directly from Frank’s diary rather than from other adaptations, a detail that separates her approach from actors who lean on prior film versions of the story.
Her formal training started at Rare Studio Performing Arts School in Liverpool, where she studied acting, dance, and musical theatre. She also became a member of the National Youth Theatre, a program whose alumni include Daniel Craig, Helen Mirren, and Chiwetel Ejiofor. Getting into the NYT is competitive, and it is often treated as an early signal of serious talent in British theatre circles.
That dual grounding in dance and stage work shows up in how directors have described her on set. Rather than a young performer who learned to act mainly in front of a camera, Boullet came up through live theatre training first, which tends to produce a different kind of physical control and comfort with long, unbroken takes.
She is also fluent in French, a skill tied directly to her early years in Paris rather than something picked up later for a role. That fluency has occasionally come up in casting conversations for European co-productions, since a British actress who can work convincingly in French widens the kinds of international projects she can be considered for.
From The Worst Witch To A Small Light
Boullet’s first screen credit came in 2020, when she joined the CBBC series “The Worst Witch” as Fenella Feverfew for its fourth series. It was a modest starting point, the kind of children’s television role that rarely leads anywhere bigger, and by her own account, the part was followed by a stretch with no bookings.
The turn came in 2022, when she was cast as Anne Frank in “A Small Light,” a National Geographic and Disney+ miniseries about Miep Gies, the woman who helped hide the Frank family during the Nazi occupation of Amsterdam. Boullet had originally auditioned for the role of Anne’s sister Margot, which went to Ashley Brooke, before landing the part of Anne instead.
The series aired in 2023 and gave Boullet her widest exposure yet. Her performance earned a nomination for the Critics’ Choice Award for Best Supporting Actress in a Movie or Miniseries, a strong marker for an actress still in her teens with only one prior credit to her name.
“A Small Light” was not built as a star vehicle for its younger cast. The show centered on Miep Gies, played by Bel Powley, with Boullet’s Anne Frank appearing in a supporting capacity drawn from real diary entries rather than an invented arc. That constraint mattered: Boullet had to work within a historical record audiences already knew, with little room to reinterpret the character for dramatic effect, and reviewers still singled out her performance as one of the show’s more affecting elements.
Billie Boullet Net Worth In 2026
Billie Boullet has not published or confirmed a net worth figure, and no verified financial filings exist for a working actress at her stage of career. Several online celebrity net worth trackers place her estimated worth at around $500,000, built mainly from acting fees on “The Worst Witch,” “A Small Light,” “Worldbreaker,” and now “Man on Fire,” along with the early stages of brand interest that tend to follow a high-profile Netflix lead role.
Earlier estimates from 2023, before “A Small Light” had even aired, ranged much lower, sometimes under $100,000, and reflected how little public data existed at that point in her career. Any of these numbers should be read as rough public estimates rather than confirmed figures, since actors’ contract terms are rarely disclosed.
What is clearer is the direction her earning potential is heading. Landing a lead role in a Netflix drama built around a recognizable book franchise, opposite an established star like Abdul-Mateen II, typically comes with a meaningfully larger paycheck than a miniseries supporting role, even before streaming bonuses or a second season are factored in.
Brand and endorsement income remains a small part of the picture for now. As of 2024, reporting on Boullet noted she had not yet taken on brand endorsement deals, unlike many young actresses who monetize a rising profile through sponsored content well before their acting income catches up. A lead role on a high-visibility Netflix series is the kind of credit that usually changes that calculation.
Worldbreaker And The Move Into Film
Before “Man on Fire” arrived, Boullet made her film debut in “Worldbreaker,” playing Willa, a young woman raised in the aftermath of an alien invasion. The cast included Luke Evans and Milla Jovovich, putting a 19-year-old Boullet alongside performers with decades of film experience. She also appeared in the 2026 project “My Brother the Minotaur” as Dana.
Moving between a British children’s series, a historical war drama, a science fiction feature, and now a Netflix action thriller in the space of six years is an unusually wide range for someone so early in a career. It suggests a deliberate effort, whether hers or her representation’s, to avoid being typecast after the attention “A Small Light” brought her.
Man On Fire: Her Biggest Role Yet
In “Man on Fire,” which premiered on Netflix in April 2026, Boullet plays Poe Rayburn, an American teenager relocated to Brazil who becomes the only witness to a violent incident and finds an unlikely protector in John Creasy, played by Yahya Abdul-Mateen II. The series is based on A.J. Quinnell’s novel, previously adapted into the 2004 film that starred Dakota Fanning in a comparable role.
Showrunner Kyle Killen, known for “Halo” and “Awake,” has said Boullet pushed to understand her character deeply rather than settle for surface-level notes, building out Poe’s inner strength alongside Abdul-Mateen’s performance. Abdul-Mateen has echoed that, describing her as an attentive scene partner who asked the harder questions during rehearsal rather than the easy ones.
Getting cast as the female lead opposite an actor of Abdul-Mateen’s profile, in a series backed by New Regency and Chernin Entertainment, marks a clear step up from ensemble and supporting work. It is the kind of role that tends to open doors to bigger, better-paying projects industry-wide, regardless of how the show itself performs critically.
Following In Dakota Fanning’s Footsteps
Most coverage of “Man on Fire” mentions the 2004 film version in passing, but the comparison is worth sitting with. Dakota Fanning played the equivalent role at age nine, opposite Denzel Washington, in a story about a bodyguard protecting a kidnapped child. Boullet plays a version of that character as an actual teenager, closer to the age Poe is written as, which changes the emotional register of the relationship at the center of the show.
A child performance built on vulnerability plays very differently from a teenage one built on growing independence and friction with the adults around her. The official character description for Poe leans into that awkward, in-between stage of adolescence, language that has little to do with how the equivalent role worked in the original film. Boullet was not asked to recreate Fanning’s performance; she was asked to build a different one from a similar premise, and that distinction has mostly gone unremarked in coverage focused on casting news and premiere dates.
Billie Boullet’s Boyfriend And Personal Life
Boullet has kept her personal life largely out of public view. She has not confirmed a boyfriend or any relationship in interviews, and there is no verified information tying her to anyone romantically. Given how closely she has guarded other personal details, that pattern is likely to continue as her profile grows.
She is an only child and has said little publicly about her parents beyond their support for her early training. Her Instagram presence has grown alongside her career but remains modest compared to co-stars with longer résumés, and she has largely avoided other major social platforms.
What Comes Next For Billie Boullet
At 21, Boullet has already worked across children’s television, a prestige historical drama, a big-budget science fiction film, and now a flagship Netflix series, all within six years of her first audition. That range, combined with a Critics’ Choice nomination before she turned 19, points toward a career built on versatility rather than a single breakout type.
Whether “Man on Fire” gets renewed for a second season or not, Boullet’s next moves will likely be shaped by the leverage a lead Netflix role provides. For an actress who started with no bookings after her first job, the shift from supporting player to headline name has happened over a remarkably short stretch.
