Watson is cast for the role of Hermione Granger in Harry Potter and the Sorcerer’s Stone. Watson recalls the audition as a happy accident when casting agents visited different British schools asking if they had any children who would like to audition. Her Oxford theater teacher recommended her to the agents and the producers were impressed with Watson’s confidence. After eight auditions, producer David Heyman told Watson and Grint that they had been cast as the lead roles of Hermione and Ron, respectively.
I was asked up to David Heymen’s office with Rupert. [He] sat me down and said, ‘You’ve got the part.’ Ahhh! It was so cool. Best experience of my life. Scariest experience of my life. Too much to take in. I was in awe.
