Katherine Parkinson: Molly Weasley in the Harry Potter HBO Series
Katherine Parkinson plays Molly Weasley in HBO’s Harry Potter series. Explore the announced role and earlier work.

Katherine Parkinson plays Molly Weasley in HBO’s Harry Potter series. Her earlier television work includes the comedy The IT Crowd and the science-fiction drama Humans, a useful pairing for anyone wanting a screen introduction beyond a single familiar role.
Katherine Parkinson as Molly Weasley
Official: HarryPotter.com names Parkinson as Molly Weasley in its cast list and in the announcement introducing the Weasleys, Dursleys and Malfoys. Our Molly Weasley guide follows the character’s place in the published story. The cast directory brings together the wider family.
Our reading suggestion: begin with the way an ordinary practical kindness can change a child’s experience of a bewildering place. Instructions, questions and introductions do more than explain a journey; they can show whether somebody feels welcome. That is a useful focus for rereading a family scene without rushing ahead to the events of later books.
Comedy: The IT Crowd
Official: BAFTA’s 2014 annual report entries Parkinson’s first BAFTA for Female Performance in a Comedy Programme in The IT Crowd. The award body’s winners list identifies her programme and category. Channel 4’s own career references also identify The IT Crowd among her work.
Our viewing suggestion: watch how a comedy performance handles somebody trying to appear more confident than they feel. The interesting moment may come just after a claim of competence, when another person responds unexpectedly. An ensemble gives that shift its rhythm: one person makes the claim, another supplies the complication, and the original speaker has to keep going.
If you return to an episode you remember, try following the reactions rather than the main joke. A sustained character can remain recognisable through small choices in pace, expression and attention. It is one way to appreciate a sitcom performance beyond remembering its most widely shared lines.
Drama: Humans
Official: Channel 4’s casting announcement names Parkinson in Humans with William Hurt, Tom Goodman-Hill, Colin Morgan and Gemma Chan. Its interview with Parkinson discusses the drama’s questions about consciousness and human relationships. The producer’s programme page identifies her as Laura Hawkins.
Our suggestion for comparing comedy and drama is to keep the surrounding scene in view. A character trying to manage an uncomfortable situation can create humour in one production and tension in another. The difference may come from the stakes, the length of a silence or what the audience knows before a conversation begins.
A family-centred speculative drama is an interesting companion to a school-centred fantasy for that reason. You can ask how a production makes an extraordinary premise feel part of somebody’s daily life. Meals, routines and disagreements can carry the invented world into recognisable experience. These are viewing questions, rather than claims about what the Harry Potter adaptation will show.
Theatre resources and recordings options
Official service checked on 17 October 2026: Disney+ has a UK listing for The I.T. Crowd, with Parkinson in the cast. Confirm your account’s access and the precise seasons offered on the service page. No price is quoted here.
For Humans, this check established official credit and interview sources, but did not establish a current UK streaming entitlement. Use the broadcaster’s programme information as a starting point and confirm availability directly with the service before paying. A historical press announcement establishes a production credit, not permanent access.
Our recommendation is to choose a complete episode and consult its content information before family viewing. The reason to explore an actor’s earlier work is the pleasure of discovering another production, rather than an obligation to complete a filmography before the new series. If you prefer to stay in the books, compare Molly’s first encounter with Harry to the way other adults introduce themselves.

A family reading question
Our book-group question: what makes a family scene feel welcoming to someone who is not yet part of the family? Readers may notice practical help, familiar teasing or a person being included in an ordinary conversation. Choose one example from the book and explain why it matters to Harry. That makes a useful starting point for comparing Molly with other adults while keeping the discussion grounded in a moment the whole group has read.
