On the last day with Daniel Radcliffe, Rupert Grint and Emma Watson, when they were on set together and filmed their final scene, what was that like?
Yates: We shot the scene on the viaduct, outside Hogwarts, and it was really peaceful. It was a really sunny day. It was all backlit. And it’s a very tender scene where they sort of reflect on everything that’s happened, all the battles and everything, and they hold hands, and the camera falls away. It’s a really tender, lovely scene.

I said to them, ‘Look, guys, this is the last scene we’re all going to do with you three together in front of the camera. So, it’s not just the last scene of these three characters in the movie, this is your last scene in this series of films. That’s what today is about.’ And it infused it with a kind of emotion which was really moving actually.

Did you ever talk to Jo Rowling about adapting these books and the choices you made, particularly in terms of its contemporary feel?
Yates: We never had a big conversation about that because it was very present in the book. She read the script and she was totally cool about the way we’d adapted it. She was always just very enthusiastic about the whole first script, generally. But she’s been really helpful and we had a good chat about a couple of scenes in Part 2. I asked her, ‘What were you thinking when you wrote these scenes?’ And she was really helpful.

Jo was a producer on this film, so how was that? How was her expanded role on it?
Yates: You know, it hasn’t really changed from the other movies, honestly. She’s just always our biggest supporter. And always very graceful and kind and I think, because she’s been there throughout, it was time her name was up there. She wants to be up there with us; it’s a real privilege.

Do you have another movie brewing after all this?
Yates: I’ve got so many scripts coming in, I can’t tell you. In fact, I told them to stop sending them. [Laughs] Because I haven’t read any of them. They’re just all piled up. But I’m so ambitious, I can’t tell you. It’s a strange thing about Harry Potter because I don’t feel any sense of ownership, in a way. I don’t feel territorial about it. I feel it’s a bit of a national treasure that I’m curating.

For everything I can enter, I try and do my very best. And I’m very proud of the work I’ve done. But post-Potter, my career sort of starts again really. And I won’t feel like I’ve made four of the biggest films in the world. I’ll feel like, ‘Well, that’s it. I’ve done Potter now.’ And I’ll have all these beautiful scripts and I can begin in a way. That’s my plan. And I’m going to do big things and tiny little things. And they won’t have wizards in them.

No wizards?
Yates: No wizards.
