Settled in cosy common rooms with glasses of Champagne, Radcliffe, Watson, and Grint reminisced about their wizarding days and how filming the Harry Potter series was a formative experience in their lives.
"I think I probably would have been about 8 years old when the first one came out," Watson said. "[Reading the books] became our family thing. My dad used to do all the voices, and my brother and I just became obsessed. We would just beg him to keep going, and every time he'd finish a chapter, we'd be like, 'One more, one more, please.'"
For The Boy Who Lived, the role was practically foreseen in Professor Trelawney's crystal ball. While thousands showed up to audition as Harry Potter, Radcliffe's parents believed the role would be too big of a disruption in his life. "I was a really happy kid who had a really haunted quality, apparently," Radcliffe said. After seeing the then 10-year-old's work in David Copperfield (1999), producer David Heyman convinced Radcliffe's father to bring him in for an audition, and the Chosen One was born.
