The Harry Potter TV series has added three notable names to its expanding Hogwarts roster, giving fans a clearer picture of what Season 2 will look like. HBO has confirmed that Rafe Spall, Molly Hewitt-Richards, and Jasper Ambrose are joining the fantasy drama as Arthur Weasley, Moaning Myrtle, and Colin Creevey, respectively, as production continues in the UK.
For viewers tracking every update around HBO’s ambitious reboot, this latest casting wave signals a deeper move into the events and characters associated with Harry Potter and the Chamber of Secrets. With filming underway at Warner Bros. Studios Leavesden, anticipation around the Harry Potter TV series continues to build.
Harry Potter TV Series Expands Season 2 Cast
The newly announced cast members will appear in Season 2 of the Harry Potter TV series, joining a growing lineup that blends established stars with rising talent.
- Rafe Spall will play Arthur Weasley, the kind-hearted Ministry of Magic employee and father of Ron Weasley.
- Molly Hewitt-Richards has been cast as Moaning Myrtle, the ghost who haunts the girls’ bathroom at Hogwarts.
- Jasper Ambrose will portray Colin Creevey, the camera-carrying Hogwarts student and devoted admirer of Harry Potter.
Each of these characters plays an important role in the second chapter of the wizarding saga, making the casting particularly significant for fans of the books and films alike.
Why These Characters Matter in Season 2
Season 2 is expected to draw heavily from Chamber of Secrets, where all three characters become especially relevant. Arthur Weasley helps broaden the wizarding world beyond Hogwarts, offering insight into magical family life and Ministry politics. Moaning Myrtle is central to one of the story’s biggest mysteries, while Colin Creevey brings youthful energy and comic relief to the school setting.
That makes these additions more than simple supporting roles. In the Harry Potter TV series, these characters will help shape the emotional and narrative texture of the season.
Who Are the New Cast Members?
Rafe Spall as Arthur Weasley
Rafe Spall steps into a role many longtime fans will instantly recognize from the original film franchise. Arthur Weasley was previously played on screen by Mark Williams, but the HBO adaptation is building its own interpretation for television.
Spall brings strong screen credibility to the Harry Potter TV series, with credits including Trying and Under Salt Marsh. There is also an interesting family link here: his father, Timothy Spall, appeared in the original Harry Potter films as Peter Pettigrew.
Molly Hewitt-Richards as Moaning Myrtle
Molly Hewitt-Richards takes on the role of one of Hogwarts’ most memorable ghosts. Moaning Myrtle, previously portrayed by Shirley Henderson, is known for her mournful presence and her importance to the Chamber of Secrets storyline.
Hewitt-Richards has appeared in Code of Silence and Casualty, and her casting suggests HBO is looking for performers who can balance familiarity with a fresh dramatic approach in the Harry Potter TV series.
Jasper Ambrose as Colin Creevey
Jasper Ambrose will play Colin Creevey, the enthusiastic student who often follows Harry with a camera in hand. Creevey made a memorable impression in the novels and in the 2002 film adaptation, even though the character did not remain prominent throughout the original movie series.
By reintroducing Colin in the Harry Potter TV series, HBO has the chance to explore side characters with more depth than the films could accommodate.
Other Major Season 2 Additions
The latest casting news comes alongside several previously revealed additions for Season 2. New names already attached to the series include:
- Kit Harington as Gilderoy Lockhart
- Bonnie Hill as Ginny Weasley
- Lenny Rush as Dobby
- Billy Barratt as Tom Riddle
Meanwhile, returning and recurring cast members include Dominic McLaughlin as Harry Potter, Arabella Stanton as Hermione Granger, and Alastair Stout as Ron Weasley. They are joined by a heavyweight adult ensemble featuring John Lithgow as Albus Dumbledore, Janet McTeer as Minerva McGonagall, Paapa Essiedu as Severus Snape, and Nick Frost as Rubeus Hagrid.
This mix of veteran actors and younger performers is one reason the Harry Potter TV series remains one of the most closely watched TV developments in fantasy entertainment.
What HBO’s Creative Team Signals for the Adaptation
Behind the camera, the project continues to take shape under writer and executive producer Francesca Gardiner. Mark Mylod is attached as executive producer and will direct multiple episodes. The series is being made for HBO in association with Brontë Film and TV and Warner Bros. Television, with J.K. Rowling, Neil Blair, Ruth Kenley-Letts, and David Heyman also serving as executive producers.
That creative lineup suggests HBO is treating the Harry Potter TV series as a prestige long-form adaptation rather than a simple retelling. The extended television format should allow more room for character detail, subplots, and book-accurate world-building.
Why Fans Are Watching These Casting Announcements Closely
Casting reveals for a franchise this beloved are never minor news. They offer clues about tone, pacing, and how faithfully the adaptation may follow the novels. In this case, the additions of Arthur Weasley, Moaning Myrtle, and Colin Creevey strongly indicate that HBO is laying careful groundwork for a richer Season 2.
For fans, the biggest question is whether the Harry Potter TV series can deliver both nostalgia and something genuinely new. So far, HBO appears to be betting on recognizable character choices, experienced creatives, and a broader canvas than the films ever had.
