I've spent three hours with Snoop Dogg, talking about how he loved [Peaky Blinders series]. And David Bowie loved it. The late Leonard Cohen was a fan. It struck a chord with various people that I didn't think it would.

[Taboo] has been exactly the same as working with the BBC in that creatively they do that precious thing which is to only make a comment when a comment needs to be made.

Suddenly, after years of television being the poor relation and film being everything, it now feels like film is a conjuring trick. It's like, "Oh, my god, how are you going to do that in 90 minutes, as opposed to eight hours?! I've got so little time to do this!" It becomes an art form, in itself. Doing both helps you do each one.

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 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.

[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.
