Meet the New Stars of the Harry Potter TV Series: Cast Revealed by HBO
The wizarding world is getting a fresh start! HBO has officially unveiled the young talents who will headline its highly anticipated Harry Potter TV series. This fresh adaptation of J.K. Rowling’s iconic book saga promises a deeper, more faithful exploration of the magical universe that captivated millions.
New Faces in Iconic Roles
After an extensive casting call that drew over 30,000 young hopefuls, three newcomers have been selected to portray the legendary trio:
- Dominic McLaughlin as Harry Potter
- Arabella Stanton as Hermione Granger
- Alastair Stout as Ron Weasley
These talented young actors are stepping into the iconic roles originally brought to life by Daniel Radcliffe, Emma Watson, and Rupert Grint in the globally beloved film series.

Who Are the New Stars?
Dominic McLaughlin, a rising Scottish actor, is no stranger to the screen. He has roles lined up in the Sky comedy Grow, where he stars alongside Nick Frost, and in the action-packed BBC series Gifted.
Arabella Stanton already has West End experience under her belt, having played Matilda in Matilda: The Musical, showcasing her ability to carry a lead role with charm and grit.
Alastair Stout may be the least known of the trio, but insiders say his audition was nothing short of magical, winning over casting directors and showrunner Francesca Gardiner.
Powerhouse Cast and Creative Team
The series isn’t just banking on new talent—it’s also stacking its roster with seasoned actors in key roles:
- John Lithgow as Albus Dumbledore
- Janet McTeer as Professor McGonagall
- Paapa Essiedu as Severus Snape
- Nick Frost as Hagrid
- Luke Thallon as Professor Quirrell
- Paul Whitehouse as Argus Filch
Behind the camera, the series boasts an impressive creative team. Francesca Gardiner, known for her work on Succession and His Dark Materials, will serve as showrunner. Mark Mylod, also of Succession fame, joins as executive producer and director. J.K. Rowling herself is attached as an executive producer, ensuring that this reboot stays true to the heart of the original novels.
A New Chapter for a Beloved Franchise
Unlike the original film series, which condensed the seven novels into eight films, this new adaptation will unfold over at least a decade. This allows the TV series to delve deeper into the beloved plotlines, characters, and magical details that were omitted or trimmed for time in the movies.
Filming is scheduled to begin in summer 2025 at Warner Bros. Studios Leavesden in the UK. If all goes according to plan, fans could expect the first season to hit HBO Max as early as 2026.
What Fans Can Expect
The new Harry Potter series is being hailed as a more “faithful adaptation” of Rowling’s books, with each season expected to cover one book in detail. This format gives the show ample room to explore story arcs and characters like never before. Longtime fans and newcomers alike can look forward to a richer, more immersive journey into the world of magic, friendship, and adventure.
