Harry Potter series casts three new roles: Arthur Weasley, Moaning Myrtle and Colin Creevey

• Rafe Spall will play Arthur Weasley, Molly Hewitt-Richards has been cast as Moaning Myrtle, and Jasper Ambrose as Colin Creevey.
• Other entertainment outlets are repeating the same casting, but the provided material does not include a direct HBO confirmation.

What happened

IGN reported that HBO’s Harry Potter series has filled three new roles. According to that report, Rafe Spall will play Arthur Weasley, Molly Hewitt-Richards has been cast as Moaning Myrtle, and Jasper Ambrose will portray Colin Creevey. The three names are being mentioned together in coverage as the latest additions to the series cast.

The same three names and roles also appear in other entertainment publications. Deadline likewise mentions Arthur Weasley and Moaning Myrtle in its own report, while Knight Edge Media says HBO officially announced the casting and also names Jasper Ambrose as Colin Creevey. However, the provided material does not include a direct statement from HBO itself, so the confirmation in this set of sources remains indirect.

The new casting fits characters from the book series who appear early in the story. Arthur Weasley is a recurring character from the second book onward, while Moaning Myrtle and Colin Creevey both first appear in Chamber of Secrets. That makes the three roles relevant to the series’ setup, since they are familiar figures who quickly become part of the original story’s world.

The reporting also references earlier casting rounds for the series. In the provided sources, Tom Riddle, Dobby, Ginny Weasley and Gilderoy Lockhart are also mentioned as previously discussed or announced roles. It is not fully clear from the material whether all of those names are tied to the same season plan, so that point remains uncertain.

Background

According to the report, Rafe Spall is currently seen in Apple TV’s Trying and has previously appeared in Life of Pi, Jurassic World: Fallen Kingdom, Men in Black: International and Black Mirror. In the original Harry Potter films, Arthur Weasley was played by Mark Williams. That means the new casting updates a role that has already appeared on screen, but is now being reworked for the TV series.

The provided sources also describe Arthur Weasley as a character who returns from the second Harry Potter book and later works at the Ministry of Magic. That background matters for the series, since the character is a key link between the Weasley family and the wider wizarding world.

For Moaning Myrtle and Colin Creevey, both characters first appear in Chamber of Secrets. In the sources, they are described as smaller but recognizable roles in the series. Moaning Myrtle is a ghost closely tied to Hogwarts, while Colin Creevey is known as a young student who admires Harry Potter. Casting those two characters suggests the series is also bringing in supporting figures from the books early in production.

The provided sources also refer to earlier casting rumors around the series, but leave uncertainty around an actor referred to as “Tom Hoult.” Based on the available information, that has not been independently confirmed. That makes this part of the reporting less solid than the three new cast names that appear across multiple publications.
