“What Jo Rowling did was really fill in the past of Albus Dumbledore and, I mean, an awful lot of his past is hinted at and referenced in the books of Harry Potter; she filled in a lot of gaps that weren’t mentioned in the books. She also gave insight and a sense of where he was going and what we hope to explore in future films. I’m actually in the process of making the third Fantastic Beasts at the moment and that’s exploring his past in a little more detail.”
