So many times after a catastrophe like 9/11, Estonia in Sweden, the Holocaust or whatever, we are so fond of lifting up the hero examples, but actually 99 percent of survivors have done something that they feel very guilty about.

I'm not a genre film filmmaker. I'd rather look for a topic that I think we need to bring up and discuss because there's something about the issues in the film.

Just look at the history of cinema. The most reproduced male character is probably the hero and the most reproduced female character is probably the sex object. I think those stereotypes have been reproduced over and over again. It also changes our expectations when it comes to a situation like this in real life.

I was very interested in highlighting group behaviour and I wanted to show that I think this is very fundamental about being a human being... that we are herd animals actually. So, I was looking for different situations that take place in different kinds of groups.

Actually men are closer to having the ability to act egoistic when it comes to a crisis situation.
