Warwick Davis, returning as Professor Flitwick in HBO's upcoming Harry Potter series, has described the show as a very faithful adaptation of J.K. Rowling's books with added depth. In a recent interview, he shared insights from the set while noting the eerie familiarity of filming at the original studios. The series is set to premiere in early 2027, spanning seven seasons over a decade.
Warwick Davis, known for his role as Professor Filius Flitwick in the original Harry Potter films, is reprising the character in HBO's ambitious television adaptation of J.K. Rowling's seven novels. Speaking to Times Radio, Davis offered a rare glimpse into production, stating, “I’m working on it at the moment, but I can’t really tell you anything other than we’re retelling those wonderful stories but with more depth and detail than has been seen before.” He emphasized the project's fidelity to the source material, adding, “They’re very faithful adaptations of the book.”
The actor highlighted similarities to the films while pointing out differences, noting, “We’re obviously telling the same story so there are similar moments that we’re experiencing as actors on the set. But it’s weird being back in the same studios again, doing it all again, because Leavesden is where we shot the films.” Warner Bros. Studios, Leavesden, served as the primary filming location for the eight Harry Potter movies, and the series is returning there for authenticity.
Davis appeared in all eight films, also portraying a goblin bank teller and voicing Griphook in "Harry Potter and the Sorcerer's Stone," though he will not reprise those roles. The new cast includes Dominic McLaughlin as Harry Potter, Arabella Stanton as Hermione Granger, and Alastair Stout as Ron Weasley. Other confirmed actors are John Lithgow as Albus Dumbledore and Nick Frost as Rubeus Hagrid.
HBO plans to release one season per book, with the first arriving in early 2027. Production chief Casey Bloys revealed that writing for season two is already underway to minimize gaps between seasons, considering the show's scale and special effects demands. The project arrives amid ongoing controversy surrounding Rowling's views on gender, which have drawn public disagreement from original stars like Daniel Radcliffe, who recently offered support to the young cast via a letter to McLaughlin.
