the main trio (Harry Potter, Ron Weasley, and Hermione Granger) and a bunch of professors at Hogwarts School of Witchcraft and Wizardry (Albus Dumbledore included). Katherine Parkinson, known for small screen projects like “Humans” and “The IT Crowd,” will portray Molly Weasley, the matriarch of the Weasley family played by Julie Walters in the films and mother of Ron (Alastair Stout is set to star as Ron). Nobody has picked up the mantle of the late Helen McCrory as Narcissa Malfoy as of this writing, but her son Draco, originally played by Tom Felton, will be portrayed by Lox Pratt; his father Lucius Malfoy, originally played by Jason Isaacs, will now be portrayed by Johnny Flynn (an actor known for “Stardust,” “Emma,” and the Netflix series “Ripley”).
Hogwarts students who start school at the same time as Harry Potter himself (who’s being played by Dominic McLaughlin) — Seamus Finnigan, Parvati Patil, and Lavender Brown — will be portrayed by Leo Earley, Alessia Leoni, and Sienna Moosah, respectively. Rounding out this casting announcement is Bertie Carvel (Tony Blair in later seasons of “The Crown”) as Minister for Magic Cornelius Fudge and Bel Powley and Daniel Rigby as Petunia and Vernon Dursley, Harry’s cruel and abusive aunt and uncle. (Powley was recently seen in “Masters of the Air,” while Rigby played the titular Waldo in “The Waldo Moment,” an early episode of “Black Mirror.”)
