Meet the talented performers behind the animated fantasy series based on Luke Pearson’s graphic novels. The voice cast of Hilda brings a rich blend of youthful energy and seasoned British acting talent to the screen, capturing the whimsical, folklore-driven atmosphere of Trolberg. Discover the actors who voice the blue-haired protagonist, her loyal friends, and the quirky mythical creatures populating her world.
The Core Cast of Hilda
At the heart of the series is a tight-knit group of friends navigating extraordinary adventures with trolls, elves, and spirits. The casting choices balance youthful authenticity with comedic timing.
Bella Ramsey as Hilda
Bella Ramsey voices the fearless, blue-haired adventurer Hilda. Before taking on this role, Ramsey gained global recognition for playing Lyanna Mormont in Game of Thrones. Their voice acting gives Hilda a fierce curiosity, stubborn independence, and genuine warmth. Ramsey captures the character's impulsive nature without losing her underlying empathy for every creature she meets, whether friendly or terrifying.
Ameerah Falzon-Ojo as Frida
Frida, the pragmatic, highly organized, and academically driven member of the trio, is voiced by Ameerah Falzon-Ojo. Falzon-Ojo brings a sharp comedic delivery to Frida's stress-induced perfectionism. Her performance grounds the magical chaos with realistic reactions, especially when dealing with dangerous spell books or organizing school clubs. As reported in latest articles by Vanity Fair, the effects are widespread.
Oliver Nelson as David
David, the cautious, bug-fearing, and chronically unlucky friend who somehow always pulls through, is brought to life by Oliver Nelson. Nelson's performance relies heavily on nervous stutters, anxious high notes, and eventual moments of unexpected bravery. Note: Ilan Galkoff provides David's singing voice in musical sequences.
Family and Companions
Beyond the main trio, Hilda's immediate circle features veteran British television actors who lend emotional weight and deadpan humor to the show.
Daisy Haggard as Johanna (Mum)
Daisy Haggard voices Hilda's mother, Johanna. Haggard, known for her work in dark comedies like Back to Life and Breeders, infuses Johanna with a weary yet fiercely protective maternal energy. She manages the delicate balance of wanting to keep her adventurous daughter safe while respecting her undeniable connection to the wilderness.
Rasmus Hardiker as Alfur Aldric
Alfur, the polite elf who files paperwork in triplicate and insists on proper protocols, is played by Rasmus Hardiker. Hardiker delivers Alfur's rapid-fire dialogue with absolute sincerity, turning bureaucratic obsession into one of the show's most reliable running gags.
Ako Mitchell as The Wood Man
The laconic, uninvited house guest who casually walks through walls and sits by the fireplace is voiced by Ako Mitchell. Mitchell speaks in a low, deadpan register that contrasts sharply with the frantic energy of the children, making every brief appearance memorable.
Trolberg Residents and Antagonists
As the series shifts from wilderness exploration to city life in Trolberg, new characters enter the narrative, expanding the vocal landscape.
John Hopkins as Erik Ahlberg
John Hopkins takes on the role of Safety Patrol leader Erik Ahlberg. Ahlberg is pompous, deeply concerned with his public image, and utterly ill-equipped for actual monster threats. Hopkins plays this vanity to perfection, creating an antagonist who is more ridiculous than genuinely menacing.
Lucy Montgomery as Gerda Gustav
Gerda Gustav, Ahlberg's fiercely competent and long-suffering second-in-command, is voiced by Lucy Montgomery. Montgomery gives Gerda a sharp, authoritative tone that highlights the absurdity of taking orders from someone far less capable than she is.
Behind the Scenes of Voice Direction
Recording voice work for an animated series like this involves distinct logistical challenges. Unlike traditional live-action projects where actors share physical space, much of the cast recorded their lines separately in London studios. Voice director Andy Field coordinated these isolated sessions to ensure natural chemistry and overlapping banter felt genuine.
The production team prioritized British and European actors who could match the specific whimsical, slightly melancholic tone of Scandinavian folklore. This casting philosophy helped maintain the distinct atmosphere of the original graphic novels created by Luke Pearson, which Netflix adapted into the Emmy-winning series.
