Harry Potter HBO Series Unveils Magical First Look in London: Dominic McLaughlin and Nick Frost Bring Iconic Characters to Life

The wizarding world is stirring once again, and this time, it’s casting a spell on television screens. HBO’s highly anticipated Harry Potter TV series has officially begun production, and the first glimpses from the London set have sent fans into a frenzy of excitement. With young actor Dominic McLaughlin stepping into the role of Harry Potter and beloved comedian Nick Frost transforming into the towering Rubeus Hagrid, the series promises to rekindle the magic of J.K. Rowling’s iconic books in a fresh, immersive way. Add to that the reveal of the Weasley family, and it’s clear this adaptation is poised to captivate both longtime fans and newcomers alike. Here’s everything you need to know about this enchanting new chapter in the Harry Potter saga.

A First Look at Harry and Hagrid in London

Filming for the HBO series kicked off in July 2025 at Warner Bros. Studios Leavesden, the same location where the original eight Harry Potter films were shot. On August 18, 2025, the streets of London became a portal to the wizarding world as cameras captured Dominic McLaughlin, an 11-year-old Scottish actor, embodying the Boy Who Lived. Sporting Harry’s signature round glasses, a casual jacket, and a backpack, McLaughlin looked every bit the part of the young wizard discovering his destiny. “I was always a huge Harry Potter fan when I was younger,” McLaughlin shared in an interview with the BBC. “And it was like the dream role, of course.” His enthusiasm for the role shines through, making him a fitting choice to carry the weight of such an iconic character.

Walking alongside him was Nick Frost, who takes on the role of Rubeus Hagrid, the gentle half-giant who introduces Harry to the wonders of Hogwarts. Frost, known for his roles in Shaun of the Dead and Hot Fuzz, appeared almost unrecognizable with long, curly hair, a bushy beard, and Hagrid’s signature khaki coat. In a nod to the character’s larger-than-life presence, Frost was spotted wearing a prosthetic mask to enhance Hagrid’s towering stature, a detail that has sparked curiosity among fans. “He’s funny! I want it to be funny and cheeky and scared and protective and childlike,” Frost said of his approach to the character in a statement to People. His vision for Hagrid promises a blend of humor and heart, staying true to the beloved groundskeeper’s spirit while offering a fresh interpretation.

The scene being filmed is believed to recreate a pivotal moment from Harry Potter and the Sorcerer’s Stone, where Hagrid guides Harry through the bustling streets to the Leaky Cauldron, the hidden pub that serves as a gateway to Diagon Alley. This iconic sequence marks Harry’s first step into the wizarding world, and the HBO series seems determined to capture its wonder with meticulous detail. The choice to film on location in London adds an authentic, grounded feel to the production, sparking intrigue about how the series will balance nostalgia with innovation.

The Weasley Family Steals the Spotlight

No Harry Potter story would be complete without the warm, chaotic charm of the Weasley family, and HBO’s adaptation has delivered a cast that has fans buzzing with approval. The roles of Ginny, Fred, George, and Percy Weasley have been filled by Gracie Cochrane, Tristan Harland, Gabriel Harland, and Ruari Spooner, respectively. Their first family selfie, shared by HBO, showcases a striking resemblance to the red-haired, freckled clan described in Rowling’s books. Katherine Parkinson, known for her work in The IT Crowd, steps into the role of Molly Weasley, the nurturing matriarch originally portrayed by Julie Walters. “The Weasley family is the heart of so many moments in the story,” Parkinson noted in a press release. “I’m thrilled to bring Molly’s warmth and strength to life for a new generation.”

Fans have taken to social media to praise the casting, with many noting how the actors’ appearances align closely with their mental images of the characters. The Weasleys’ home, The Burrow, is expected to play a significant role in the series, offering a cozy contrast to the grandeur of Hogwarts. With each season adapting one of Rowling’s seven books, viewers can look forward to spending plenty of time with this beloved family, from their mischievous antics to their unwavering loyalty to Harry.

A Faithful Adaptation with a Modern Twist

HBO has promised a “faithful adaptation” of J.K. Rowling’s novels, with each of the seven books unfolding over its own season. This long-form format allows for a deeper exploration of the wizarding world, diving into subplots and character arcs that the films couldn’t fully capture. J.K. Rowling, serving as an executive producer, has expressed her enthusiasm for the project’s potential. “I’m looking forward to being part of this new adaptation which will allow for a degree of depth and detail only afforded by a long-form television series,” she said in a statement to Time. Her involvement ensures that the series stays true to the spirit of the books, while the creative team, led by showrunner Francesca Gardiner and director Mark Mylod, brings a modern sensibility to the storytelling.

The casting process for the series was nothing short of monumental, with over 32,000 young actors auditioning for the roles of Harry, Ron, and Hermione. Alongside McLaughlin, Arabella Stanton and Alastair Stout were selected to play Hermione Granger and Ron Weasley, respectively, rounding out the iconic trio. Stanton, who previously starred as Matilda in the West End’s Matilda: The Musical, and Stout, a newcomer with a northern accent, bring fresh energy to these beloved characters. The chemistry between the three young actors will be crucial, and early reports suggest their dynamic is already sparking magic on set.

Additional cast members include John Lithgow as Albus Dumbledore, Janet McTeer as Minerva McGonagall, and Paapa Essiedu as Severus Snape, adding star power to the ensemble. The series also features a diverse range of talent for other Hogwarts students and faculty, such as Rory Wilmot as Neville Longbottom and Louise Brealey as Madam Rolanda Hooch. This blend of established actors and fresh faces creates a sense of anticipation about how the series will reimagine familiar characters while introducing new depth to their stories.

Why This Series Is Set to Enchant Audiences

The Harry Potter TV series is more than just a reboot—it’s a chance to rediscover the wizarding world through a new lens. By filming at Warner Bros. Studios Leavesden and on location in London, the production team is grounding the story in the same magical settings that defined the original films. The attention to detail, from Frost’s prosthetic-enhanced Hagrid to the updated Gryffindor uniforms, suggests a commitment to honoring the source material while offering something distinctly new.

For fans, the series is a nostalgic return to Hogwarts, but it’s also an opportunity to experience the story with greater depth. The extended format allows for richer character development and the inclusion of book details that were cut from the films, such as the intricate dynamics of the Weasley family or the full scope of Harry’s journey. The first season, set to premiere in 2027, will adapt Harry Potter and the Sorcerer’s Stone, setting the stage for a decade-long adventure.

A Magical Journey Awaits

As production continues, the Harry Potter HBO series is shaping up to be a must-watch event for fans old and new. Dominic McLaughlin’s heartfelt connection to the role, Nick Frost’s playful yet poignant take on Hagrid, and the vibrant Weasley family are just the beginning of what promises to be a spellbinding journey. With J.K. Rowling’s vision guiding the project and a talented cast bringing the wizarding world to life, this adaptation is poised to cast a powerful charm. Whether you’re a Gryffindor, Hufflepuff, Ravenclaw, or Slytherin, the magic of Hogwarts is calling—and it’s never been more exciting to answer.
