I remember Emma and Rupert being very, very sweet when one of the journalists, presumably knowing that I didn’t know the books too well, asked a question like, ‘Who is Tom Marvolo Riddle, really?’ I had no idea. But I was also aware that both Emma and Rupert were writing down the answer next to me and trying to slide it across the table - like the world’s press weren’t going to notice? But it was very sweet and a good day.
