HBO’s upcoming Harry Potter series has found its Hermione. Arabella Stanton will bring the beloved character to life alongside Dominic McLaughlin as Harry and Alastair Stout as Ron. More than 30,000 young actors auditioned after an open call last fall, but Stanton’s performance as Matilda in London’s West End production of Matilda: The Musical helped her stand out.
Arabella Stanton Becomes the New Hermione
Stanton, who starred as Matilda from 2023 to 2024, impressed casting directors Lucy Bevan and Emily Brockmann with her poise and honesty. At just 12 years old, she’ll tackle the role first made famous by Emma Watson. Showrunner Francesca Gardiner and executive producer–director Mark Mylod praised Stanton’s “wonderful talent” and said they “cannot wait for the world to witness their magic onscreen.”
Arabella Stanton’s casting answers a key question: What is Arabella Stanton’s ethnicity? While details of her background remain private, Stanton’s theatrical skills and warm presence promise to make Hermione’s intelligence and courage shine.
