True stories are always good because they're so odd, and so unlikely.

Whenever I see a cut of a film and something is gone, I don't notice it unless it obviously should have been kept.

There were three options [in Allied], which were for [Bred Pitt] to shoot [Marion Cotillard], for them to escape, or for her to pull the trigger, which is a heroic act to spare him. When I was thinking about how it would end, a long time ago, I think I tried each of them to see, but two of them did not work.

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

With FX in particular, they've been fantastic and were really hands off. I mean, it helps that you've got Ridley Scott on your side.

I was 21, when I heard the story that inspired this [thriller Allied], and I wasn't even a screenwriter then.

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.
