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.

I don't think that jealousy and love and hate and anger and all those things have changed in the past 200 years - people just express themselves differently.

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

I'm not suggesting that ours [series] is unique in that, but they can begin to have that depth, that gravity, they can spend some time, so it's a bit more like reading a good novel, if you like.

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.

I think certain periods of history don't get dealt with because I think historians, and it's their job, but they look back and look for patterns. They look for sequences and they look for reasons, and certain periods of history don't fit with the general pattern of 1500 to the 20th century, during which there's the creation of the United States. At this time of 1814, two nations who would eventually become close allies were at war with each other, so it doesn't quite fit.

When you're watching, I find two things happen. You either watch a film and it's really good and then you think, "Why can't I do that?" Or you watch a film and it's not good, and you think, "Why am I doing this?" So either way, it feels like being at work.
