LAW I think Dumbledore feels somewhat isolated, and that in order to progress and do the right thing he’s going to have to face up to demons that he’s carried, and actions that he’s taken in his past. He is also in a situation where he relies on others to believe in his causes, and act for him. So that leaves, in its wake, rather a lot of… I suppose guilt, in a way. He’s complicated. But you know, unmistakably, as is mentioned in all the books, he has this sparkly and mischievous quality, which is such a lovely thing to be able to sprinkle in.
I did [go back and watch Richard Harris and Michael Gambon’s performances], but I was freed up immediately by Jo Rowling and David Yates, who said, “Come on, there are 80-odd years between them. You’re not him yet.” There are little things I wanted to pick up on that Harris and Gambon did, but it was just an excuse to go back and get into the world. What am I doing this weekend? I’m going to watch all of the Harry Potter films and pretend I’m taking notes!
