‘David [Yates] said he got Eddie Redmayne to read with so many actresses but he knew immediately that you were Tina. That you had such perfect chemistry and it had to be you.’
Katherine Waterston: ‘Oh! Oh, really? That’s too nice. I bet he was like, “Don’t tell her that, it’ll go to her head!” Oh, he’s such a dear man. He brings so much joy to the set, but the real thing that trickles down from the top is his faith in this process because he’s been in this world before.’

‘Usually on a movie, you’re going into new territory together and you’re like, “Is there quicksand around the corner, are there going to be wolves attacking?” Whereas David’s been here before so he’s just like, “You’re going to take a left here and avoid the quicksand”.

‘He has a shorthand and a comfort with the world. He’s not precious with it, he understands what it needs and what it doesn’t need and there’s something really comforting in that.’

‘When we’re incorporating things that aren’t actually there, to look at David and know he can see the world is... everything.

‘It’s sort of like when your parents read you a book when you’re a kid; if they read it with passion and curiosity, you can see the whole world.’

‘Ah, this movie. It’s so clever and it’s rooted in truth. It’s got light, funny elements and then much darker, more adult elements. I normally don’t respond so well to innocent lovely things, I think, “come on, let’s get on with it”. But there’s something about this script and the way J.K. Rowling writes; it’s tender without being saccharine. It never lingers on the sweet parts but maybe that’s a slightly English thing: “Oh I felt something – moving on!” No, really, it’s a beautiful film. It’ll kill me to finish filming it.’
