It begins with knowing the story you want to tell. There are thousands of stories contained within the world that Samantha has created – we have to be very disciplined about opening up the world in a way that will lead us on to further investigation in the rest of the series. We need to find the emotional heart of the story; the relationships; the tension; the suspense and the drive; and of course working closely with Samantha is going to make it much easier.

Choosing parts is based on a series of instincts and hunches

I know what you mean, but there are two kinds of voids, the one that you work with and the one that you bear. I work with and try to generate a void. I pick up the guitar and I let my mind wander until it gets distracted and suddenly it lost its purpose. It’s just wondering between one chord and the other, one subject or the other, or maybe I would just be distracted watching a film and something moves me, or the light in the window and then I let that feeling guide me. I always use this metaphor. It’s like getting into a garden at night and suddenly perceiving a perfume of a tree or a flower. You don’t know exactly where it’s coming from, but you know there’s something there, so you start sniffing around until you find it. You get closer and closer to the source until you identify it. That’s the way I write. What I mean is that suddenly something crosses my mind and I just follow that. I try not to lead at the beginning. I try to follow and then whenever I find that I take, I use reason and I organize. I say, “Wait, I need a second part with the same structure. I need a bridge. I need a chorus. Let’s go. Let’s move to this place. Let’s change this rationally,” but the core has to be subconscious.

Obviously, it’s different for everyone. And actually there is a difference for each thing I do. But one way it happens is to just move. [ laughs ] I mean, obviously, you don’t just sort of randomly throw yourself around the room. You move with these ideas and sometimes I find that I’ve already got images in my head that I imagine my body in, or sometimes I have sequences in my head. I think a lot of time I’m listening to what comes next because sometimes the body will tell you that. Often I don’t document it too early in the process because sometimes if you forget stuff it’s worth knowing that the things that you forget maybe weren’t worth keeping. The things that have settled are the things that need to be kept because they seem most urgent. I don’t know. I mean, sometimes it’s about going to the studio and nothing happens for a long time and you just sit there and you’re not feeling it. That’s awful. It’s like when you’re writing and sometimes you go to the coffee shop and you’re like, “So, we’ll just see what happens.” And you end up on Facebook. I think the answer to this is… I really think the answer to this is I don’t know. [ laughs ]

There is an awful lot of pious theatre at the moment, where you go to have what you already believed reinforced.

you have no idea where your power, if you have any power, comes from and then, when it vanishes, you have no idea why it’s vanished.

I took Nicole out to dinner for the first time on 19 October, 1991. After that, everything changed.

I would like to write a play which doesn’t disappoint me 20 years later.

All good dramatists are scared of the audience.
