For me, when I see movies where I kind of know who the characters are and what the situation is, I get bored. To me, it's, "How do I tell a story that will keep the audience engaged?" A great story does that: it's not exactly what you expect.

Every movie is a surprise. That's what is so fun about it. You can be planning a movie for years, and then you'd better be surprised every day, or it's going to be stale.

It's great when you can bait and switch people - and I don't mean that in a negative way, I mean that in truth. If we were advertising this movie as a very serious indictment about the hunt for war criminals, and it's a very dark drama, it would probably get great reviews, but people would stay away from it because no one wants to be lectured.

We're all so jaded. We've seen so many movies. We know what's going to happen in every single movie. I mean, there are some movies where I'm like why do I even need to keep watching? And so, if you can make a movie in which you're completely surprising the audience left and right, and left and right, then you've won. If a jaded film critic or reporter or an audience is like, "I didn't see that one coming," that to me is like a victory.

I think people are a mixture of everything. I like desperate characters because they do things that most of us normally wouldn't do. If a character is a scoundrel or a liar you think you know them, but then I can bring some emotion to them and they become much fuller than you ever imagined. So what I try to do is have a story where you don't quite know where it's going, and characters who you don't quite know where they're going.

I'm not making a movie about the real people. I'm making a movie about what they did, and what happened to them. But I will create characters so that I can have the freedom to make them say and do what I want. The real-life journalists were fine with that.
