Alastair Stout is a young British actor, born around 2013 or 2014, who has been cast as Ron Weasley in HBO’s upcoming television series adaptation of J.K. Rowling’s *Harry Potter* books, set to premiere in 2026. Announced on May 27, 2025. Stout was selected from over 32,000 auditionees in an open casting call for children aged 9 to 11.

There is limited public information about Stout’s prior acting experience, suggesting he may be a relative newcomer to the screen. His casting has been highlighted by HBO and the creative team, with J.K. Rowling and executive producer Francesca Gardiner praising his suitability for the role of Ron Weasley, a character known for his loyalty and humor. Stout’s selection marks a significant milestone in his budding career, stepping into a role previously portrayed by Rupert Grint in the original film series. Unlike his co-stars in the Harry Potter series on HBO Max, Alastair has no major acting credits — except a commercial for Albert Bartlett promoting Jersey Royal potatoes.
