I've been writing so much. And what happens with TV is that they split [Taboo] into two blocks, so you get a director that does four and another director that does another four. You commit yourself to seven days a week, for 12 or 13 hour days for a long time. I couldn't really do that.

[Allied] got the attention of (director) Bob Zemeckis and Marion Cotillard. I'm glad I waited. If it had been made 15 years before, who knows how it would have looked, but it's got the best possible cast, director and everything. It's been fantastic. It was worth waiting.

East India Company weren't an evil organization that went around deliberately oppressing people, but they were driven by profit, and how familiar is that now?

It felt [at the Allied set] like, "At last, I'm in Hollywood," even though I was in West London. It was like, "This is how a film should be made." It was beautiful.

Just the idea that someone is married and they've got a kid, and he reports for work one morning and his boss says, "You're wife is a spy. Shoot her." In the real story, he just went back and did it, which would have been a short film. Therefore, I had to spend some time exploring what you would do.

[The film Woman Walks Ahead] is from a long time ago. I wrote that ages ago. It looks gorgeous and Jessica [Chastain] is so good that I've got high hopes.

It's great that the story [Allied] is set in the '40s because the '40s feel to it is completely appropriate.
