It's always good to have a world that people don't know about - a world that hasn't yet been done. It's like treading on fresh snow. You're the first one there.

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].

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.

It's such a gift when you know who you're writing for and you know that that actor is capable of so much that you can relax a bit.

The story of James Delaney is also someone who very deliberately presents himself as an individual and plays nations against each other, plays the East India against the Crown, all of those sort of overwhelming concepts that ran the world at the time.

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.
