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

I've realized that the only thing I'm interested in is the performance. If the performance is right, then I'm happy. You offer up the dialogue and then the performance comes around.

I relish the eight-hour format of a single season because it gives you time to do that.

[Allied] meant to be a film that's a bit different. It's roots are in the '40s and '50s, and that sort of filmmaking style.

There were three options [in Allied], which were for [Bred Pitt] to shoot [Marion Cotillard], for them to escape, or for her to pull the trigger, which is a heroic act to spare him. When I was thinking about how it would end, a long time ago, I think I tried each of them to see, but two of them did not work.

I'm very, very excited because I'm just completing Episode 6 of Series 4 [of Peaky Blinders], which again I think is the best yet. And I'm loving it and it's not like work, it's not like a labor, I love doing it, and the boys are coming back and they're loving the scripts.

[The film Woman Walks Ahead] is from a long time ago. I wrote that ages ago. It looks gorgeous and Jessica [Chastain] is so good that I've got high hopes.
