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.

Snoop [Dog] said [Peaky Blinders] reminded him of how he got involved with gang culture. It's always fantastically flattering when I see people dress like that and take on the look.

[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.

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].

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

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.
