J.K. Rowling has given her "absolute blessing" to Olivier-winning British thesp Noma Dumezweni for her role as an adult Hermione Granger in the upcoming London stage production "Harry Potter and the Cursed Child". When the casting was first announced last year, Rowling said she never defined Hermione's race in the books and said she 'loved' the idea of a non-white actress filling the character's shoes.
