HBO's Harry Potter reboot has confirmed its first returning star from the original film franchise. Warwick Davis, who played Professor Filius Flitwick across all eight films, will step back into the role for the upcoming television adaptation. The announcement was made during the Back to Hogwarts celebrations on September 1, a date fans recognize as the day students return to the wizarding school.
Davis became a familiar face in the franchise not only as Flitwick but also as Griphook, the goblin banker at Gringotts. In the new series, however, he will focus solely on Flitwick, while actor Leigh Gill takes on Griphook.
Alongside Davis, a number of fresh cast members have been revealed. Sirine Saba has been cast as Herbology teacher Pomona Sprout, Richard Durden will play ghostly History of Magic professor Cuthbert Binns, and Bríd Brennan will appear as the school nurse, Madam Pomfrey.
On the student side, Elijah Oshin will play Dean Thomas, with Finn Stephens and William Nash taking on the roles of Crabbe and Goyle, Draco Malfoy's ever-present companions. Draco himself will be played by Lox Pratt.
The central trio has already been introduced, with Dominic McLaughlin as Harry Potter, Arabella Stanton as Hermione Granger, and Alastair Stout as Ron Weasley. Other key names include John Lithgow as Albus Dumbledore, Paapa Essiedu as Severus Snape, Nick Frost as Rubeus Hagrid, Janet McTeer as Minerva McGonagall, and Johnny Flynn as Lucius Malfoy. Bel Powley and Daniel Rigby will take on Petunia and Vernon Dursley, while more roles, such as Neville Longbottom, the Weasley siblings, and Dudley Dursley, have also been filled.
Filming is underway at Warner Bros.' Leavesden Studios in the U.K., with additional scenes shot around London. Fans recently caught sight of McLaughlin in Harry's round glasses walking beside Frost, dressed in Hagrid's signature coat.
The series is being developed as a seven-season project, with each season adapting one of J.K. Rowling's books. Francesca Gardiner is writing and executive producing, with Succession director Mark Mylod also attached as an executive producer. Rowling herself is listed among the producers, alongside Neil Blair, Ruth Kenley-Letts, and David Heyman, who worked on the original films.
The first season is expected to premiere in 2027 on HBO and HBO Max, giving the Wizarding World a new look while keeping familiar connections through returning cast members like Davis.
