I think that it's not a bad thing to not be too versed in the vocabulary of cinema, because you start to think that certain things are allowed and not allowed.

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.

With any period piece I think the thing to do is forget that it's not contemporary when you're writing and to have the characters feel as much as possible like characters that you would know.

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.

[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.

The story [of Allied ] itself is the story I wrote, and that's what's great about Bob [Zemeckis ]. You have meetings, but it's meetings for clarity, not to change what they're saying or doing. He takes what's on the page and executes it so brilliantly.

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.
