When I was probably about 10 or 11, and I found it was simply something I could do. When you're at school and you do something and you get praised for it, you think, "Oh, right, well I'll do that." From then on, I always thought I'd be a writer. I thought novels at first, and then I sort of naturally drifted into TV.

There's something about the evolution of television where it evolved from to the things that we're now watching and loving. It evolved from film writers, film actors, and I think gradually people are easing themselves into the amount of time they have.

If you've read something brilliant, it's good. It's good to look out the window and see what's going on in the world.

You know that when you suggest something on the page, it's going to be there, plus more. It's a great luxury to know that you don't have to push it. You just lay it out, and it will be there.

[Allied] got the attention of (director) Bob Zemeckis and Marion Cotillard. I'm glad I waited. If it had been made 15 years before, who knows how it would have looked, but it's got the best possible cast, director and everything. It's been fantastic. It was worth waiting.

I always thought it would never happen. And then, it became possible. In between commissions, I wrote it as an original screenplay [Allied].

I find the best way to make things real is to just put two characters into a space and let them talk to each other in the way that they would talk to each other, and then see what they would say. I know it sounds weird, but that leads the plot and takes you in another direction.
