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.

I think people are drawn to characters that break the rules. I think there is something about a good person doing bad things for what they consider to be a good reason. Then the battle is on to almost prove to the audience that it's justified. How far can you go with that? How far can that character go before people won't accept it? Trying to walk to edge of that line is a challenge.

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.

Sometimes if you're a director, you want to believe that you're great and capable at all aspects - the technical side, the lights, everything - but I'm not.

The sandstorm, which I think is an absolute triumph, could have been awkward. It's sex in a car, so who knows. And I think the rooftops look fantastic [in Allied].

The plan is that there would be three seasons [in Taboo], and, as with Peaky Blinders, I have had a destination in mind from the beginning, because I think it helps as a writer. The destination in mind is that James Keziah Delaney sets foot on Nootka Sound. But that's a long way off.

What happened was I was invited to meet Tom [Hardy] to discuss a project that he had in his mind about an adventurer who returns to England from Africa with secrets and with a history, and the original idea was set some 80 years later than it is now. But in the conversation I really took to the idea and I'd wanted for a while to set something in 1830 and 1840 in London, so it struck a chord.
