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.

I like to create a character where you believe, deep down, that they don't really care if they live or die. That's very liberating for the character because, if the character is prepared to die, then they can do anything. It's impossible to stop them.

Whenever I see a cut of a film and something is gone, I don't notice it unless it obviously should have been kept.

It has to be an actress like Marion Cotillard [in Allied] because there are so many levels to it. It's set in the Second World War, when lots of people were doing things that, outside of a war, you wouldn't do, like killing and dropping bombs. She's doing things that one wouldn't approve of, but it's war.

[2015] it's a time that there's a clash of ideologies, similar to the Cold War. I think that a story like this has been waiting to be told, and I think it's a fresh look at the whole earth-shattering business of the collapse of the Soviet Union.

No screenplay is possible, unless you get some attachment from somebody who's going to get it made.

I think that helps because there has been no formality of friendship, the politeness of friendship, so we can just work directly on the work that's ahead of us [with Tom Hardey].
