Arabella Stanton plays Hermione in HBO’s Harry Potter. She 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 London and was announced on 27 May 2025, when she was 11.

Unlike her co-stars, she arrived with stage experience: she played Matilda in Matilda the Musical in London’s West End from September 2023 to March 2024, and Control in Starlight Express in 2024. She is also the only member of the trio who plays the same character twice: she voices Hermione in the full-cast audiobooks published by Audible since 2025 [Wikipedia].

How the books describe Hermione Granger, and every difference so far, is on the character page.

In interviews

“I think books are the main connection between Hermione and I,” she told the Associated Press [ComicBookMovie].

To Scholastic News she said that the series includes material from the books that was not in the films: see the interview.
