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.

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

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.

If you've read something brilliant, it's good. It's good to look out the window and see what's going on in the world.

I love cooking and kitchens.It's just a great world, and I wanted to explore it. You see the façade, the outside, the public part, and then you just walk through one door marked "Staff Only" and you're in a different universe.

[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.

I visited the set [of Allied] a few times, and it was a great set to visit. A lot of it was in West London, in an old Gillette factory. You'd go into the factory through the security, and then there were a lot of camels and goats. Most sets are really dull, but this was fantastic.
