LOS ANGELES — HBO has officially announced the first six actors cast in its highly anticipated “Harry Potter” television series, set to debut in 2026. The series, described as a faithful adaptation of J.K. Rowling’s original novels, aims to delve deeper into the wizarding world than the original films.
Filming is scheduled to commence this summer at Warner Bros. Studios Leavesden in Hertfordshire, England.
Here are the first six casting announcements, along with who played those characters in the film series.
Film and TV veteran John Lithgow will portray the wise and enigmatic headmaster of Hogwarts. Lithgow’s extensive career includes acclaimed roles in “3rd Rock from the Sun,” “Dexter” and “The Crown,” showcasing his versatility and depth as an actor.
He takes over the iconic role from Richard Harris, who portrayed Dumbledore in the first two films, and Michael Gambon, who took on the role for the remaining installments of the original franchise.
Janet McTeer, known for her performances in “Tumbleweeds,” “Ozark” and “The Woman in White,” will bring to life the stern yet caring Transfiguration professor.
McTeer has rich stage and screen experience, which is promising as she takes on the complex and integral McGonagall. McTeer takes on the role previously held by the legendary Maggie Smith, who brought McGonagall to life in all eight films of the original series.
Paapa Essiedu, recognized for his work in “I May Destroy You” and “The Capture,” will take on the role of the enigmatic Potions Master. Essiedu’s performances have garnered critical acclaim, and his casting has sparked significant discussion among fans.
Essiedu steps into the shoes of the legendary Alan Rickman, whose portrayal of Snape became iconic, both for its complexity and depth, across all eight films.
Nick Frost, celebrated for his comedic roles in “Shaun of the Dead” and “Hot Fuzz,” will portray the lovable half-giant Keeper of Keys and Grounds.
Frost’s unique blend of humor and heart is expected to bring a fresh dynamic to the character. He takes over for Robbie Coltrane, who embodied the role of Hagrid for all eight films, leaving behind an unforgettable legacy in the Harry Potter universe.
Paul Whitehouse, a veteran comedian and actor, will embody the cantankerous Hogwarts caretaker. Known for his work on “The Fast Show” and “Harry & Paul,” Whitehouse has comedic timing and experience, which could be great for the role.
Whitehouse steps into the role originally played by David Bradley, who portrayed Filch in all of the films.
Luke Thallon, an emerging talent in British theater, will portray the timid Defense Against the Dark Arts professor. Thallon’s stage credits suggest a nuanced performance that could add depth to Quirrell’s character.
Thallon takes on the role previously played by Ian Hart in the first film, “Harry Potter and the Sorcerer’s Stone.”
Casting call for young wizards
In September 2024, HBO issued an open casting call for children aged 9 to 11 from the UK and Ireland to audition for the roles of Harry Potter, Hermione Granger and Ron Weasley. The casting process emphasized inclusivity and diversity, with over 32,000 children auditioning for the coveted roles. Filming for these roles is expected to begin in mid-2025.
Looking ahead
As production progresses, fans can anticipate further casting announcements, including the iconic trio of Harry, Hermione and Ron. With a decade-long commitment to the series, HBO aims to deliver a richly detailed adaptation that honors the beloved books while introducing new elements to captivate both long-time fans and newcomers.
