The time came where I was able to write an original screenplay [Allied], and it would be read and noticed. I had a meeting with Brad [Pitt], just around the time that he was making World War Z. I basically told him the story and said, "This is what I want to do," and he really responded, so that helped me put the thing together and write it.

I read more and more and I came across this character, Caroline Weldon. Sometimes in history, you find these people that no one would dare create. They're too mad.

I think the East India Company represents what we would think of as a very modern approach to the world where everything was counted, every penny was counted.

In other words, when you have someone [like Ridley Scott] with that authority, then you tend to be left alone. But they were good and they're really good people, and I'm a big champion of the BBC and I think that like minds find each other and I think that FX and BBC is a perfect match.

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.

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.

There's something about the evolution of television where it evolved from to the things that we're now watching and loving. It evolved from film writers, film actors, and I think gradually people are easing themselves into the amount of time they have.
