Fresh Casting Choices for HBO's Anticipated Harry Potter Series

Published on May 3, 2026, at 9:35 AM EDT, Screen Rant welcomes Memory Ngulube to its Movies and TV team. Previously a freelance copywriter specializing in email marketing and social media, Memory now thrives as a Classic TV writer, crafting stories spanning timeless classics to contemporary films and series. Outside her writing duties, she enjoys reading, baking, and indulging in her favorite K-dramas.

When not penning articles, Memory immerses herself in literature, experiments with culinary creations, or binge-watches compelling K-shows—passions that fuel her imaginative storytelling.

Meanwhile, HBO’s forthcoming Harry Potter adaptation assembles a fresh roster of performers to bring the wizarding world to life. The series promises both reverence for the original films and bold new interpretations, starting with the first novel’s iconic professors.

Professor Septima Vector, a figure absent from the early films, makes her debut through actress Svetlana Karabut, whose recent roles in No Time To Die and The Radleys showcase her versatility. Though largely unknown to mainstream audiences, Karabut’s nuanced performances hint at a promising contribution to the franchise’s legacy.

Professor Cuthbert Binns, the history teacher whose dry delivery became legendary, is portrayed by Richard Durden. Best recognized for his work in From Paris With Love and Bridgerton, Durden’s gravitas promises to elevate the classroom scenes central to the series’ magic.

Professor Pomona Sprout, the nurturing Herbology instructor, finds a new voice in Janet McTeer. A veteran of stage and screen, McTeer brings depth to the character, balancing warmth with quiet authority—a refreshing contrast to previous portrayals.

Professor Filius Flitwick, the affable Charms teacher, is reimagined by Warwick Davis. Known for roles ranging from Leprechaun to The Hitchhiker’s Guide to the Galaxy, Davis infuses the role with endearing charm, ensuring spells and laughter abound in the classroom.

Quirinus Quirrell, the cursed professor infamous for his nervous demeanor, takes on a younger face via Luke Thallon. Drawing from theatrical roots, Thallon balances vulnerability and mystery, embodying the duality of a student haunted by dark forces.

Professor Severus Snape, the enigmatic potions master, is portrayed by Paapa Essiedu. After initial skepticism over his casting, Essiedu’s performance honors the character’s complexity, blending intensity with subtle sorrow—a testament to his commitment to nuanced storytelling.

Professor Minerva McGonagall, the stern yet compassionate Transfiguration teacher, is brought to life by Janet McTeer. Her established presence adds gravitas, bridging the gap between tradition and change in Hogwarts’ halls.

Albus Dumbledore, the series’ iconic headmaster, is entrusted to John Lithgow. A seasoned actor with a penchant for intellectual roles, Lithgow captures Dumbledore’s wisdom and wit, promising a portrayal steeped in both warmth and gravitas.

Finally, Professor Grindelwald’s legacy looms large, but the series shifts focus to Hogwarts’ living heart—its teachers. Each actor brings unique strengths, ensuring the magical world feels both familiar and freshly imagined.
