The industry has changed in big ways. When I started making movies, the studios were not all owned by huge conglomerates, so the decisions were made in a very different way. Over the years, I've watched both the rise and the decimation and fall of the DVD as a portion of where you could generate revenue from making this kind of content. We've seen this change in the balance sheet on the international side of the ledger; it's now a much bigger percentage than it is on domestic, even though movies would have been previously really domestically driven.

Somebody asked me, "When was the last time it was harder for you as a woman"? And I was like, "What time is it? Do you mean today?" I hate to say that, because it sounds so depressing, but it absolutely happens in many many ways all the time, large and small ways. But it's not like it creates new pain for me on a daily basis, it's just a pain that I accepted long ago. It's definitely harder.

For me and movies - and it is kind of similar to motherhood and raising your children - I always feel like there's more you can do, and I don't know if that's particularly a female quality. I don't know how dads feel, but there's definitely a never say die, no stone unturned, never give up a minute that you could be pushing it down the road and try to make it better.

You want to put people together who will work well, and each movie kind of has its own personality in terms of how people are working or the temperature on set, and we want people who will fit in with that mix. It's one of the really important parts of it.

The hard thing for me, and it took me many years to understand, the concept of Hollywood not being a meritocracy - I am a middle child, and as most middle children will tell you, that never goes away, wishing the world was fair and understanding.

Just watching Chris Nolan direct was amazing. He is one of the most lovely people, which as you know doesn't always go hand-in-hand with great directors. But with Christopher Nolan, and there's only a few I think like him in Hollywood, that's absolutely true.

That can be undersold, I think, the importance when you're trying to do something good is that everybody understands the director's vision, everybody believes in it, and everybody can find their own path to supporting it, and that's how you end with a great movie.
