On July 14, 2025, HBO officially kicked off production on its highly anticipated television adaptation of J.K. Rowling’s beloved Harry Potter series, releasing the first behind-the-scenes photo of young Dominic McLaughlin in full Hogwarts regalia. The 11-year-old Scottish actor, cast as the titular boy wizard, was seen donning the iconic round-rimmed glasses, Hogwarts robe, and, of course, the famous lightning bolt scar on his forehead, instantly evoking memories of Daniel Radcliffe's portrayal in the original film franchise.
The production began at Warner Bros. Studios Leavesden in Hertfordshire, the very same location where the eight Harry Potter films were shot, signaling a nostalgic return to the magical grounds that brought the wizarding world to life for millions. HBO has announced that this new series will be a faithful adaptation of the seven-book saga, with each season dedicated to one of Rowling's novels, promising a sprawling narrative expected to span the next decade or more.
Alongside McLaughlin, the casting has revealed a fresh and diverse ensemble of talent to bring the beloved characters to the small screen. Arabella Stanton and Alastair Stout will portray Hermione Granger and Ron Weasley, respectively, completing the central trio that fans worldwide have cherished for over two decades. The casting process was monumental, with over 30,000 young actors auditioning for these pivotal roles, highlighting the immense anticipation and passion surrounding the project.
July 14 also saw the announcement of several new cast members joining the Hogwarts family. Rory Wilmot was named Neville Longbottom, a fan-favorite Gryffindor known for his resilience and growth throughout the series. Amos Kitson will play Dudley Dursley, Harry’s muggle cousin, notorious for his spoiled and bullying demeanor. Louise Brealey, famed for her role as Molly Hooper in Sherlock, steps into the role of Madam Rolanda Hooch, the flying instructor and Quidditch referee. Anton Lesser, known to many as Qyburn from Game of Thrones, takes on the role of Garrick Ollivander, the legendary wandmaker whose shop is a rite of passage for every young wizard.
These newcomers join a star-studded cast of seasoned actors who bring gravitas to the adult roles. John Lithgow, an acclaimed actor with multiple Emmy and Golden Globe awards, will portray Albus Dumbledore, Hogwarts’ wise and enigmatic headmaster. Lithgow reflected on his casting in a February interview, saying, “It was not an easy decision because it’s going to define me for the last chapter of my life, I’m afraid. But I’m very excited.”
Paapa Essiedu, an Emmy-nominated British actor known for his work in HBO’s I May Destroy You, was cast as Severus Snape, a role that sparked controversy and discussion when announced due to the character’s iconic status and Essiedu’s casting as a Black actor. Jason Isaacs, who portrayed Lucius Malfoy in the original films, publicly criticized the “rude” comments surrounding Essiedu’s casting, defending the choice and emphasizing the importance of diverse representation.
Other notable adult cast members include Janet McTeer as Minerva McGonagall, the stern but caring deputy headmistress and head of Gryffindor House; Nick Frost as Rubeus Hagrid, the lovable half-giant gamekeeper and Care of Magical Creatures professor; and Katherine Parkinson as Molly Weasley, the matriarch of the Weasley family who becomes a second mother to Harry.
The casting extends to several other key characters: Daniel Rigby as Vernon Dursley, Harry’s notoriously unpleasant uncle; Bel Powley as Petunia Dursley, his aunt; Bertie Carvel as Cornelius Fudge, the Minister of Magic; Lox Pratt as Draco Malfoy, Harry’s school rival; Johnny Flynn as Lucius Malfoy, Draco’s father; and Paul Whitehouse as Argus Filch, the cantankerous Hogwarts caretaker.
Supporting roles for Hogwarts students Seamus Finnigan, Parvati Patil, and Lavender Brown will be played by Leo Earley, Alessia Leoni, and Sienna Moosah respectively, while Luke Thallon takes on the role of Quirinus Quirrell, the Defense Against the Dark Arts teacher in Harry’s first year. This well-rounded cast promises to breathe new life into the rich tapestry of characters that fans have adored for years.
The production team also boasts experienced professionals, including director Mark Mylod and director of photography Adriano Goldman, both of whom have previously worked on acclaimed series such as The Crown. Hair and makeup designer Cate Hall, also from The Crown, joins the team, ensuring the series will have the visual authenticity and detail that fans expect.
HBO CEO Casey Bloys confirmed the series is slated for a 2027 debut, marking nearly 14 years since the last Harry Potter film, “Deathly Hallows: Part 2,” hit theaters. This new adaptation will explore the stories with the depth and nuance that only a long-form television format can offer, allowing for a more faithful and expansive retelling of the novels’ complex plotlines and character development.
One notable difference from the films is the commitment to keeping characters the same age as in the books. This means viewers will see a younger Severus Snape, only 31 years old, and a younger Dursley family, contrasting with their older portrayals in the films. Whether any original film cast members will make cameo appearances remains unknown, but Daniel Radcliffe has expressed excitement about watching the new series as a fan.
The Harry Potter franchise, which began 28 years ago, has since grown into a global phenomenon encompassing blockbuster movies, a Broadway play, video games, and theme parks. This HBO series aims to reignite that magic for a new generation, with a cast and crew dedicated to honoring the source material while offering fresh perspectives and inclusivity.
As filming commences, fans around the world eagerly await the chance to return to Hogwarts and relive the adventures of the boy who lived, now through the lens of a decade-spanning television epic. With its blend of fresh faces, seasoned actors, and a commitment to authenticity, HBO’s Harry Potter series looks poised to enchant audiences all over again.
