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.

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.

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.

I feel like you can have entertainment, and you can laugh, but during that period of time you can also think, and people should get upset. America is spending a lot of time and money pretending to be searching for people who we're not really searching for. That is enough to get someone angry.

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.

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.

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.
