Fans of the Wizarding World are buzzing as HBO reveals more details about its highly anticipated Harry Potter series, set to premiere in 2027. Among the exciting news is that Warwick Davis, beloved for his portrayal of Professor Flitwick in the original films, is reprising his role. Alongside Davis, several notable actors join to bring to life students and professors at Hogwarts, promising to capture the magic and depth of J.K. Rowling’s beloved novels in new ways.

A Blend of Newcomers and Familiar Faces

The series promises a fresh take on the story of 11-year-old Harry Potter, chronicling each book across multiple seasons in a way never before attempted on screen. The main trio—Harry, Hermione, and Ron—will be played by newcomers Dominic McLaughlin, Arabella Stanton, and Alastair Stout, respectively, after an extensive global search with over 30,000 screen tests for the iconic roles.

In addition to Warwick Davis’s return as the charming and quick-witted Professor Flitwick, the series features new actors cast in classic Hogwarts student roles: Joe Bursnall as Dean Thomas, Richy Jackson-Stewart as Vincent Crabbe, and Finlay Wright as Gregory Goyle. Their inclusion promises a rich and authentic Hogwarts experience with a diverse and talented ensemble.

Exploring the Depths of Hogwarts Staff

Alongside Davis, acclaimed actors fill out the school’s faculty: John Lithgow stars as the venerable headmaster Albus Dumbledore, Janet McTeer takes the role of Professor Minerva McGonagall, Paapa Essiedu embodies the complex potions master Severus Snape, and Nick Frost portrays the beloved gamekeeper Rubeus Hagrid. This cast unites theater and film veterans, infusing the series with gravitas and nuance.

The involvement of these seasoned performers signals an ambitious production aiming to stay true to the spirit and tone of the books while exploring characters in greater depth compared to the original film adaptations.

Returning to Leavesden Studios and Immersive Production

Filming takes place at Warner Bros. Studios Leavesden in Hertfordshire, England—the same iconic location used for the Harry Potter film series. The production recreates Hogwarts and its magical surroundings with modern technology, aiming to blend fidelity to the source material with cinematic innovation.

Showrunner Francesca Gardiner and director Mark Mylod emphasize the series’ dedication to faithful storytelling while introducing new perspectives. Each season will focus on a single book, allowing richer, more detailed exploration of Harry’s journey and the evolving wizarding world.

What Fans Can Expect From the Series

This HBO adaptation aims to reintroduce the magic to new generations while delighting longtime fans. With J.K. Rowling as executive producer, the show is positioned as a definitive screen version capturing the books’ complexities, humor, and heart.

The casting of beloved returning actors like Warwick Davis alongside fresh faces highlights the series’ balance of nostalgia and renewal. Fans can anticipate not just a remake, but a deep dive into Hogwarts’ world that expands character backgrounds and stories.
