Deep Look
HBO Unveils Next Generation of Hogwarts Heroes
LONDON — May 28, 2025 — HBO has officially named the young stars who will lead its much-anticipated “Harry Potter” TV series reboot. After months of speculation and a casting call that drew more than 30,000 hopefuls, Dominic McLaughlin, Arabella Stanton, and Alastair Stout have been selected to portray Harry Potter, Hermione Granger, and Ron Weasley.
The young actors step into roles immortalized by Daniel Radcliffe, Emma Watson, and Rupert Grint in the original Warner Bros. film saga. Now, a new generation of talent is poised to bring the iconic trio back to life in a decade-long adaptation that promises to more closely follow J.K. Rowling’s beloved books.
From Stage to Screen: Who Are the New Leads?
Dominic McLaughlin, a Scottish actor, is already gaining recognition for his work in the upcoming Sky comedy Grow, where he stars alongside Nick Frost. He’ll also appear in the BBC’s new action-adventure series Gifted.
Arabella Stanton is no stranger to magic, having played the title role in Matilda: The Musical in London’s West End. Her casting as Hermione Granger has already excited fans who’ve praised her stage presence and acting depth.
Alastair Stout, the newcomer stepping into Ron Weasley’s shoes, brings fresh talent to the role, though fewer details about his prior experience have been released, signaling an introduction to many audiences.
Veteran Cast Rounds Out Hogwarts Staff
The young cast will be supported by an impressive lineup of seasoned performers. Emmy winner John Lithgow will portray Albus Dumbledore, while acclaimed actress Janet McTeer takes on Professor McGonagall. Paapa Essiedu, known for I May Destroy You, will deliver his own spin on the complex character of Severus Snape.
Nick Frost (of Shaun of the Dead fame) is set to play the lovable half-giant Hagrid. Luke Thallon joins as Professor Quirinus Quirrell, and comedian Paul Whitehouse will portray Argus Filch, the cantankerous caretaker.
Further casting announcements are expected as the expansive Harry Potter universe continues to fill out with fresh faces.
J.K. Rowling Returns as Executive Producer
HBO has confirmed that author J.K. Rowling is closely involved with the series and will serve as an executive producer. The network emphasized that the show will be a “faithful adaptation,” a key reassurance for fans concerned about narrative deviations.
Showrunner Francesca Gardiner (His Dark Materials) and executive producer/director Mark Mylod (Succession) are leading the creative direction of the project.
“The talent of these three unique actors is wonderful to behold,” Gardiner and Mylod said in a joint statement. “We cannot wait for the world to witness their magic together onscreen.”
What to Expect: A Series Decade in the Making
Unlike the original film series, the HBO adaptation will be spread across ten years, allowing each season to cover a single book. This extended format is designed to explore deeper subplots, character development, and world-building details that the films had to condense or omit.
Filming will begin in the summer of 2025 at Warner Bros. Studios Leavesden — the same location used for the original movies. The first season is expected to debut on HBO Max in 2026.
