HBO’s Harry Potter Series Adds Three New Cast Members for Season 2

HBO’s highly anticipated Harry Potter television series is continuing to take shape, with three new actors joining the ensemble for Season 2. The additions — Rafe Spall as Arthur Weasley, Molly Hewitt-Richards as Moaning Myrtle, and Jasper Ambrose as Colin Creevey — signal that production is moving forward at a vigorous pace at Warner Bros. Studios Leavesden in the UK.

The series, which aims to bring J.K. Rowling’s beloved wizarding world to a new generation of viewers, has been generating significant buzz since its announcement. These latest casting choices reflect an ambitious approach to expanding the storyline beyond what was explored in the original film franchise.

New Cast Additions Signal Expanded Storylines

The three new actors bring a mix of established and emerging talent to the HBO Harry Potter universe. Each portrays a character with deep roots in the source material, suggesting that Season 2 will delve into corners of the wizarding world that fans have long been eager to see on screen.

Their casting follows the announcement of several other key Season 2 additions, including Kit Harington as the charismatic Gilderoy Lockhart, Bonnie Hill as Ginny Weasley, Lenny Rush as the house-elf Dobby, and Billy Barratt as a young Tom Riddle. Together, these roles indicate that the series is building toward some of the most memorable plotlines in the Harry Potter canon.

Rafe Spall Steps Into Arthur Weasley’s Role

Rafe Spall takes on the role of Arthur Weasley, a pure-blood wizard who works at the Ministry of Magic and is the father of seven children — including Ron Weasley, Harry Potter’s closest friend. In the original film series, the role was portrayed by Mark Williams. Spall’s casting continues a family tradition in the wizarding world: his father, Timothy Spall, played Peter Pettigrew (Wormtail) in the films.

Spall is well known for his work in television, with notable credits including Sky’s Under Salt Marsh and the Apple TV comedy Trying. He is represented by B-Side and UTA. His experience across both drama and comedy should serve him well as he steps into a role that requires warmth, dry humor, and a genuine love for all things Muggle.

Molly Hewitt-Richards Takes On Moaning Myrtle

Molly Hewitt-Richards has been cast as Moaning Myrtle, the ghost who haunts the second-floor girls’ bathroom at Hogwarts — a location that plays a pivotal role in Harry Potter and the Chamber of Secrets. Shirley Henderson portrayed the character in the original films, bringing a memorable blend of melancholy and humor to the role.

Hewitt-Richards, whose credits include the BritBox series Code of Silence and the BBC drama Casualty, is represented by Curtis Brown Group. The character of Myrtle has been a fan-favorite presence in the books and films, and finding an actress who can capture both the humor and the pathos of a ghost trapped in a bathroom for decades will be a meaningful challenge.

Jasper Ambrose Cast as Colin Creevey

Jasper Ambrose, known for The Sheep Detectives, will play Colin Creevey, the Muggle-born Gryffindor student who first appears in Harry Potter and the Chamber of Secrets. Creevey is known for his boundless enthusiasm for Harry Potter, often spotted around the Hogwarts grounds with a camera in hand, fanboying over the Boy Who Lived.

In the 2002 film, Hugh Mitchell portrayed Creevey, but the character did not return for subsequent installments. The decision to bring Colin back for the HBO series suggests that Season 2 will explore the Battle of Hogwarts and its aftermath, where Creevey’s story takes a dramatic turn. Ambrose is represented by the Sylvia Young Agency.

The Full Season 2 Ensemble

The Harry Potter HBO series has assembled a remarkable ensemble for its ongoing run. The principal cast includes:

• Dominic McLaughlin as Harry Potter
• Arabella Stanton as Hermione Granger
• Alastair Stout as Ron Weasley
• John Lithgow as Albus Dumbledore
• Janet McTeer as Minerva McGonagall
• Paapa Essiedu as Severus Snape
• Nick Frost as Rubeus Hagrid

With the inclusion of Season 2 newcomers alongside this core group, the series is positioned to adapt some of the most emotionally charged material in the Harry Potter books, particularly as the storyline moves into the second year at Hogwarts and beyond.

Production and Creative Leadership

The series is written and executive produced by Francesca Gardiner, with Mark Mylod executive producing and directing multiple episodes. The show is produced by HBO in association with Brontë Film and TV and Warner Bros. Television. J.K. Rowling, Neil Blair, and Ruth Kenley-Letts of Brontë Film and TV serve as executive producers, alongside David Heyman of Heyday Films, who produced all eight of the original Harry Potter films.

This creative team brings a deep understanding of both the source material and the demands of prestige television. Heyman’s involvement ensures continuity with the film legacy, while Gardiner and Mylod are tasked with translating the books’ narrative depth into a serialized format that can do justice to Rowling’s sprawling story.

What the New Casting Means for Harry Potter Fans

The addition of Spall, Hewitt-Richards, and Ambrose represents more than just filling roles — it reflects the series’ commitment to exploring the wider Hogwarts community with the depth that only a long-form television format can offer. Characters like Arthur Weasley, Moaning Myrtle, and Colin Creevey are integral to the books’ richness, and bringing them to life with fresh talent signals that HBO is serious about honoring the full scope of Rowling’s universe.

With filming actively underway at Leavesden and the Season 2 roster continuing to grow, the Harry Potter series is rapidly becoming one of the most ambitious television productions in recent memory. Fans around the world will be watching closely as this new chapter in the wizarding world unfolds.

As production progresses, casting announcements will likely continue to reveal the scale and vision of this reimagined HBO Harry Potter series — one that aims to honor its cinematic past while forging a distinct identity on the small screen.
