“To not look at, and embrace, all the things that we love about Dumbledore would have been foolhardy, but, at the same time, I was really relieved that David [Yates] and Jo both said, ‘Look, there’s so much yet formed, yet resolved in this man’s…

“Fantastic Beasts is giving me this opportunity to explore all of that and reveal things that I’ve had in my mind for a long time. So that’s enormously satisfying, but I’m inventing too. So, it’s taking all of the things that I thought happened and…
