Alastair Stout plays Ron in HBO’s Harry Potter, his first major role. He was one of the more than 30,000 children who answered the open casting call of September 2024, for children aged 9 to 11 living in the United Kingdom or Ireland, auditioned in Manchester and was announced with Dominic McLaughlin and Arabella Stanton on 27 May 2025. His age has not been made public; the open call was for children who would be between 9 and 11 in April 2025.

How the books describe Ron Weasley, and every difference so far, is on the character page.

In interviews

In his interview with Scholastic News he talked about the pressure of being only the second actor to play Ron, after Rupert Grint, and about a stunt on the giant chessboard: see the interview.
