Harry Potter TV Series Casts Arthur Weasley, Moaning Myrtle and Colin Creevey

HBO’s Harry Potter TV series has found its Arthur Weasley, Moaning Myrtle, and Colin Creevey, with Rafe Spall cast as Ron’s dad.

Spall currently stars in Apple TV series Trying, though has also had roles in Life of Pi, Jurassic World: Fallen Kingdom, Men in Black: International, and Black Mirror.

Portrayed by Mark Williams in the original Harry Potter movies, Arthur Weasley is the good-natured patriarch of the Weasley family, and a recurring character through the Harry Potter series from the second book onwards.

It is Arthur’s love of Muggle objects that ensures Harry and Ron can get to Hogwarts in an enchanted Ford Anglia, and in later stories Arthur’s position in the Ministry of Magic allows Harry to hear the inner workings of the wizarding world as Voldemort ascends to power.

Other roles announced today include ghostly schoolgirl Moaning Myrtle and the photography-obsessed Colin Creevey. Both have small roles throughout the series, though first pop up in Chamber of Secrets as victims of a mysterious creature slithering around Hogwarts castle. Here, the pair will be played by newcomers Molly Hewitt-Richards and Jasper Ambrose, respectively.

Earlier this month, HBO announced a trio of other key roles for its second season of its Harry Potter adaptation, which now has actors cast for Tom Riddle (AKA the young Lord Voldemort), Dobby the house-elf and a new face for Ginny Weasley. Game of Thrones star Kit Harington will play Gilderoy Lockhart, meanwhile, filling in for Tom Hoult who dropped out due to a recent filming delay.

This month also brought our best look yet at the series’ upcoming first season, including a peek at Quidditch, Professor Snape and the Sorting Hat. That’s due to begin airing at Christmas this year, with the now-filming second season expected to follow in late 2027 or 2028.
