You always know when one of the first ["Harry Potter" movies] are on TV, because you'll get a text message from one of your friends saying, "How high was your voice?" It's like watching a home movie, in some sense. But you just remember because the audience sees the scenes as they're written, but we remember shooting [the scenes] and all the stories that came around it. Like the Quidditch World Cup in ["Harry Potter and the] Goblet of Fire," it's like the Glastonbury Festival at Leavesden [Studios].

I think it's cool to play characters who are very joke-y and yet you can show a total serious, very somber side to them. You don't normally get that in a film - and in a [film] series especially. To be able to do that was really cool.
