The upcoming Harry Potter HBO TV series has cast its Draco Malfoy, Lucius Malfoy, Molly Weasley and a number of other key roles. Katherine Parkinson, best known for The IT Crowd, will portray Molly Weasley, mother of Ron Weasley and matriarch of the Weasley clan, as played by Julie Walters in the previous Harry Potter films.

Newcomer Lox Pratt has been cast in the key role of Draco Malfoy, Harry Potter’s blond Slytherin rival who serves as his Hogwarts antagonist throughout the series. Lovesick actor Johnny Flynn will meanwhile portray Draco’s father, the scheming Lucius Malfoy.

Other roles cast today include a number of other newcomers as Harry (and Draco)’s fellow Hogwarts students, such as Leo Earley as Seamus Finnigan, Alessia Leoni as Parvati Patil, and Sienna Moosah as Lavender Brown.

As the series nears the beginning of its shooting schedule, we now know the majority of its key roles, including the three newcomers who will play its main trio: Dominic McLaughlin as Harry Potter, Arabella Stanton as Hermione, and Alastair Stout as Ron.

First to be announced for the series was veteran actor John Lithgow as Albus Dumbledore, with subsequent cast updates naming Janet McTeer as Minerva McGonagall, Paapa Essiedu as Severus Snape, Nick Frost as Rubeus Hagrid, Luke Thallon as Quirinus Quirrell, and Paul Whitehouse as Argus Filch.

The Harry Potter TV series is expecting to begin filming its first season this year, with a debut on HBO planned for late 2026 or the beginning of 2027. The plan is for the show to adapt one book per TV season, with the full story to be told over the course of the next decade.
