Have you got anything you’re most looking forward to putting on film? The final battle, maybe?
Well, the final battle, but there’s so much. I love the character stuff. I love the resolution of Dumbledore and Snape. I love the multiple Harries at the beginning. I love the scene of Hermione trapped at the Malfoys’. I love Harry and Hermione in the forest. I think there’s so much, it’s such a rich fabric. What we’ve done now, which I think is really exciting, is that we’ve found thematic centres for each of the films. That gives the film heart. I think it’s pretty great that David Yates has crystalised it and…it’s early days still, so I’m not going to say too much. But I’m just thrilled that David Yates decided to come back, because he’s really found a new spirit for the sixth film and as we talk about seven, it’s very different as well. I think it’s going to be good.

edit:i just had to include tht in!
