Finding the right person to play Harriet Manners was never going to be easy. If you grew up reading Holly Smale’s semi-autobiographical novels, you know Harriet isn't just a "nerd." She’s a hyper-specific whirlwind of social anxiety, encyclopedic knowledge, and accidental grace. When Netflix finally dropped the adaptation, the internet immediately started buzzing about the cast of Geek Girl. It wasn't just about finding actors who looked the part; it was about capturing that awkward, endearing energy that made the books a global hit. Honestly, the casting directors kind of nailed it by leaning into fresh faces rather than overexposed stars.
The Heart of the Show: Emily Carey as Harriet
Emily Carey isn’t exactly a stranger to big-budget productions. You probably recognize them from House of the Dragon, where they played the young Alicent Hightower. But Harriet Manners is a total 180 from the high-stakes politics of Westeros. Carey, who is neurodivergent in real life, has been vocal about how much this role meant to them. They didn't just play Harriet; they lived her.
It shows.
The way Carey handles Harriet’s "fidgets" and her literal-mindedness feels authentic, not like a caricature. In the show, Harriet is a 15-year-old who knows everything about the prehistoric era but nothing about how to talk to a boy without tripping over her own feet. When she gets scouted by a modeling agency during a school trip to the Clothes Show, the chaos starts. Carey’s performance anchors the entire series, making Harriet’s transition from a bullied schoolgirl to a high-fashion model feel earned rather than just a fairy tale trope.
Why Nick Park Matters
Liam Woodrum plays Nick Park, the male lead and Harriet’s primary love interest. Nick is the "supermodel with a heart of gold" archetype, which could have been incredibly boring. Woodrum, however, gives Nick a groundedness. He’s not just a pretty face in a leather jacket. He’s the first person who sees Harriet’s "geekiness" as a feature, not a bug.

Their chemistry is the engine that drives the romantic subplot. It’s sweet. It’s awkward. It’s exactly what teen drama fans wanted. Woodrum’s career is definitely one to watch after this; he brings a relaxed charisma that balances out Carey’s high-energy neuroticism.
The Supporting Cast of Geek Girl: More Than Just Background Characters
The show succeeds because the world around Harriet feels populated by real people, even when they’re being ridiculous.
Sarah Parish as Jude Paignton is a masterclass in "stony fashion mogul." Parish is a veteran of British television, and she brings a sharp, intimidating edge to the modeling agency head. She’s the one who sees the "it factor" in Harriet’s clumsiness. Opposite her is Emmanuel Imani as Wilbur Evans. If you need a laugh, Wilbur is your guy. He’s the eccentric scout who discovers Harriet, and Imani plays him with a frenetic, joyful energy that prevents the fashion world scenes from feeling too cynical.
Then we have the family.

- Tim Downie as Richard Manners: Harriet’s dad is the ultimate "girl dad." He’s quirky, supportive, and fiercely protective. Downie plays the role with a warmth that makes the Manners household feel like a safe haven from the bullies at school.
- Jemima Rooper as Annabel Manners: As the stepmother, Annabel could have been a cliché, but Rooper plays her as the sensible, grounding force of the family. She’s the one trying to keep Harriet’s feet on the ground while her head is in the clouds of the fashion industry.
The Antagonists and Allies
You can’t have a teen drama without a villain, and Rochelle Harrington as Nat (Harriet’s best friend) and the various school bullies provide that necessary friction. The relationship between Harriet and Nat is actually one of the most realistic portrayals of "best-friendship-under-pressure" seen on TV recently. As Harriet gets famous, Nat feels left behind. It’s messy. It’s painful. It’s exactly how 15-year-olds actually act.
Decoding the Production: Behind the Scenes
The cast of Geek Girl didn't just appear out of thin air. The production, a co-production between the UK and Canada, took place across London and Ottawa. This explains the slightly polished, international feel of the cinematography.
Holly Smale herself was heavily involved in the process. Having the author in the room ensures that the "soul" of the book remains intact, even when plot points have to change for television pacing. For instance, the show ages Harriet up slightly compared to the first book, which allows for more complex romantic tensions and a deeper exploration of her identity.
Why This Specific Cast Works for 2026
Audience expectations have shifted. People don't want "perfect" anymore. We want "relatable." The cast of Geek Girl works because they look and act like people you might actually meet, even the ones who are supposed to be international models.

There’s a specific nuance to how the show handles neurodiversity. By casting an autistic lead actor in an autistic-coded role, the show avoids the "savant" tropes that plagued earlier media. Harriet’s brain works differently, and the cast supports that narrative without making her the butt of the joke. This is a massive win for representation in the YA space.
Surprising Facts About the Casting Process
- Emily Carey’s Audition: They reportedly felt a "soul connection" to the script immediately, which isn't just PR talk; Carey has spoken at length about their own late-stage autism diagnosis and how Harriet mirrored their personal journey.
- Liam Woodrum’s Background: Before landing the role of Nick, Woodrum was relatively unknown. The casting team deliberately looked for someone who didn't have the "baggage" of a major franchise.
- The Wilbur Effect: Emmanuel Imani improvised several of Wilbur’s more eccentric lines, adding a layer of spontaneity to the fashion show sequences.
The Fashion World Through the Cast's Eyes
The fashion in Geek Girl is almost a character itself. The cast had to undergo "modeling camp" to learn how to walk—or in Harriet’s case, how to walk badly on purpose. Watching Emily Carey transition from a confident gait to a stumbling, "Geek Girl" walk is a testament to their physical acting skills.
The contrast between the drab school uniforms and the avant-garde designs by Yuji (played by Sandra Yi Sencindiver) creates a visual language that mirrors Harriet’s internal growth. Sencindiver brings a quiet, intense authority to the role of the designer, serving as a mentor figure who values Harriet for her uniqueness rather than her ability to fit in.
