I was 21, when I heard the story that inspired this [thriller Allied], and I wasn't even a screenwriter then.

I'm always interested in characters who are closed down, but who open up when they choose to, rather than when they're obliged to. I think that's a very appealing thing, for an audience and just in life. I like the idea that something will say nothing, and then get straight to the point. That feels like how your heroes should be.

There's more to come. Series 4 [of Peaky Blinders] is coming soon. But I'm proud of making my hometown, which is considered to be completely unfashionable, slightly fashionable. People actually know where it is now.

I love cooking and kitchens.It's just a great world, and I wanted to explore it. You see the façade, the outside, the public part, and then you just walk through one door marked "Staff Only" and you're in a different universe.

I wanted to take a damaged individual in a damaged society with damaged relationships between nations and take a look at how this individual survives amongst them, and that for me as a writer is the connection that you needed to get inside the skin of the main character and wonder how he's going to cope with all this.

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.

I think the East India Company represents what we would think of as a very modern approach to the world where everything was counted, every penny was counted.
