Auditions for the main roles in the Harry Potter franchise lasted for a long time — the director/producers could not find the right person to play Hermione. Finally, JK Rowling herself joined in the search. One day she happened to chat with Emma Watson over the phone, and was totally delighted by the results. At many points during the conversation, the 10-year-old girl talked incessantly, not letting the writer get a word in. This made Rowling think she’d be an ideal choice to portray Hermione in the movies.
