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.

Even when you're casting, casting is always one of the weirdest subjective areas. You can get a group of people who would decide and say, "This person is a great actor and this person is less than a great actor," but there will always be somebody else who likes that person better than you based on their experience in their other films.

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.

I don't think actually that kind of ego check or "I could do better" mentality probably serves better in Hollywood, because it's definitely not a meritocracy. You can look at any number of careers and sort of see that they don't really make sense if it was only based on your movies working either creatively or financially. There are people that move ahead without that, and there are people that don't move ahead even if they did have that.

The crazy thing is, I sent out 200 letters and I got one job interview, and I actually got that job, which was working as a development assistant at Joel Silver's company. I always say that to people when they ask "What do I do?" and I'm like, "Look, I didn't get ten responses, and I didn't get five interviews, but I got one interview, and I got the job," and that was all I needed.

Somebody pointed out to me that there's no horror film on my resume, which is true, but I also don't really go see those movies. Although when I was thinking about it, I was thinking "I would probably have a really nice beach house if I made a horror movie." They seem to be very popular. I just don't think it's my thing.
