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.

The sandstorm, which I think is an absolute triumph, could have been awkward. It's sex in a car, so who knows. And I think the rooftops look fantastic [in Allied].

Sometimes you take something because it's an offer and it's big and it's good money and you have to absolutely respect that process, because it's not easier.

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.

When Brad [Pitt] responded [to Allied], suddenly what was impossible became possible, which was great. But along the way, whenever I told the story, it had an affect on people. At its core, this was an effective story.

I'm always interested in characters who are closed down, but who open up when they choose to, rather than when they're obliged to. I think that's a very appealing thing, for an audience and just in life. I like the idea that something will say nothing, and then get straight to the point. That feels like how your heroes should be.

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