His Instagram post described the experience as “a real homecoming,” resonating with fans who associate him with Hogwarts’ charm-filled classrooms.

The Back to Hogwarts announcement revealed seven additional cast members, filling out Hogwarts’ halls with both students and staff. Elijah Oshin will play Dean Thomas, a Gryffindor and friend of Harry Potter, while Finn Stephens and William Nash take on the roles of Vincent Crabbe and Gregory Goyle, Draco Malfoy’s loyal sidekicks.

On the faculty side, Sirine Saba steps into the role of Professor Pomona Sprout, previously played by Miriam Margolyes, and Richard Durden will portray the ghostly Professor Cuthbert Binns, a character never seen in the films.

Bríd Brennan joins as Madam Poppy Pomfrey, the skilled healer of Hogwarts’ Hospital Wing. These additions signal a commitment to expanding the wizarding world’s depth.

What Makes This Series a Faithful Adaptation?

HBO’s Harry Potter TV series, set to debut in 2027 on HBO and HBO Max, aims to be a faithful adaptation of J.K. Rowling’s seven books, with each season covering one novel.

Unlike the films, which faced time constraints, the series format allows for deeper exploration of subplots and characters. Filming is underway at Warner Bros. Studios Leavesden, the same location used for the original movies, ensuring a familiar yet refreshed Hogwarts.

The series is led by showrunner Francesca Gardiner and director Mark Mylod, with Rowling as an executive producer, promising a blend of loyalty to the source material and new storytelling opportunities.

How Does the Cast Compare to the Original Films?

The series introduces a new generation of actors, including Dominic McLaughlin as Harry Potter, Arabella Stanton as Hermione Granger, and Alastair Stout as Ron Weasley.

Notable names like John Lithgow as Albus Dumbledore, Janet McTeer as Minerva McGonagall, Paapa Essiedu as Severus Snape, and Nick Frost as Rubeus Hagrid round out the faculty.

While Davis is the only returning film actor, the fresh cast aims to honor the legacy of their predecessors while bringing unique interpretations. For instance, Nick Frost has expressed a desire to make Hagrid “funny” while respecting Robbie Coltrane’s iconic portrayal. This balance of old and new is a key draw for fans.

When and Where Can Fans Watch the Series?

HBO’s Harry Potter TV series is slated for a 2027 premiere, available on HBO and HBO Max in markets including the U.S., Germany, Italy, and the U.K.

Filming locations include Leavesden Studios and various London sites, such as Borough High Street and King’s Cross, evoking the wizarding world’s iconic settings.

The Back to Hogwarts celebration, a global event on September 1, served as the perfect stage for these announcements, reinforcing the series’ connection to the franchise’s traditions. Fans can expect a multi-season journey that revisits Hogwarts with fresh faces and familiar magic.
