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.

Same thing for the bad guy. People were really after this guy Radovan Karadicz. But I came up with a combination of several people, who then became The Fox. That's who Simon Hunt and Duck are after. I did that so I could have freedom with what The Fox said and did, so that I didn't have to be stuck. Certain things I wanted to stay to the truth. Certain things I changed, and certain things are the facts.

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.

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.

If you have that group of people who are both nice and also creative, then you have surprises like a room with monkeys in them. That has taken a very good scene and just made it a great scene. I want my movies to be visually interesting and to have a lot of energy and be colorful and full of life.

As a writer, it's fun to free yourself enough to tap into some darker elements of your personality that sometimes I don't even know exist. It doesn't feel like work.

So I like switching it up. I like that people are laughing but they don't even know if they should be laughing. I think that's interesting. I think it makes for a fun movie. And you're far more likely to be able to actually get something into someone's head if they don't quite see it coming, as opposed to delivering a very serious examination.
