The Pottermore Correspondent recently posted a two part (1, 2) interview with some of the Harry Potter and the Cursed Child creative team. They spoke with director John Tiffany and writer Jack Thorne about their creative collaboration with J.K. Rowling. They talk about their first meeting with Rowling where they decided on a plot for the play:

Right now, John and Jack are on a lunch break between workshops for the Cursed Child. We’re sitting at a table covered in scripts, highlighters and blunt lead pencils.

‘I’ve said it before and I’ll say it again, I’d do anything he asked me to do,’ Jack says, pointing his thumb back at John.

‘Oh, stop it,’ John says and turns to me. ‘We went to Edinburgh to Jo’s house – Jack and I. Then I sort of watched the love affair begin. You know, it’s like taking your best friend to meet your new partner and then realising… Well, it was two writers meeting, you don’t get a look in.’

‘I’d read all the books in my twenties and I’d go to the cinema and watch all the films by myself. I was deeply in love with Potter already, so the chance to do this…’ says Jack, like he still can’t believe J.K. Rowling has given him characters from those books and films to write onto the stage.

‘We started talking about ideas and her generosity in the way she listened to what was inside our heads, and then fed into that with her brilliant mind, was incredible. You were very clear back then, John, that you didn’t want to do something historical.’

‘No prequels!’ says John, echoing J.K. Rowling’s Twitter account. ‘But also, I knew from seeing the excitement in the kids I’d shared the books with that we had to bring darkness back. There had to be new jeopardy.’
