The story, neutrally told

Mixed · 2HBO's upcoming Harry Potter series has cast five more Season 1 roles, with David Threlfall as the voice of the Sorting Hat. Centre · 1Deadline notes that Threlfall, a BAFTA winner, led the original UK Shameless as Frank Gallagher, and that the announcement came on Halloween eve. Mixed · 2Leo Bill will play Gryffindor ghost Nearly Headless Nick, Andrew Brooke will play Slytherin ghost the Bloody Baron, and Daniel Fearn will play Hufflepuff ghost the Fat Friar.

Mixed · 2Laura Smyth will play the Fat Lady, the portrait guarding the entrance to Gryffindor House; Screen Rant notes she is not a ghost. Centre · 1/Film says the casting was revealed in an Instagram post from the official HBO and Harry Potter accounts, and notes that no casting has been announced for Ravenclaw's ghost, the Gray Lady. Centre · 1/Film also says Peter Serafinowicz will play Peeves the Poltergeist, a character cut from the original films, in which Rik Mayall had played him.

Centre · 1Screen Rant, citing an HBO press release, says the characters were rarely important to the main storyline in the films, and recalls that John Cleese played Nearly Headless Nick, and Elizabeth Spriggs and then Dawn French played the Fat Lady. Mixed · 2Season 1, based on Harry Potter and the Philosopher's Stone, debuts on HBO and HBO Max on 25 December 2026. Mixed · 2Dominic McLaughlin plays Harry, Arabella Stanton Hermione and Alastair Stout Ron, with John Lithgow as Dumbledore, Janet McTeer as McGonagall, Paapa Essiedu as Snape and Nick Frost as Hagrid.

Centre · 1Deadline lists agency representation: Curtis Brown for Bill, United Agents for Brooke and Smyth, GDA Management for Fearn and Independent Talent for Threlfall. /Film's writer says they are among the sceptics who wonder what the series offers beyond the films.

Every sentence links to the reporting it rests on. The pill in front of each says where its sources sit: Left, Centre or Right when one side supplies at least half of them, Mixed when they are evenly split. The number is how many outlets it cites.
