When I was writing the script, I knew didn't want to make a sports movie. I was very clear that I wanted to make a sibling rivalry story. So when I was writing the script, the football was getting in the way of the drama. One day, I saw Michael Haneke's Funny Games, which is probably the most violent film I've ever seen - but the violence is off camera. When I finished watching the film, I said, 'Hey, that's what I have to do.' Haneke gave me this solution.
I have an agent in Hollywood and he's looking for material. If I get the offer and I feel I relate to that material, I will do it. I would love to do a horror film, a thriller, a tearjerker... I like diversity. I would just like to sustain my sense of humour!
The only moment football really stops is with a penalty kick - and that is a moment that is really dramatic. A penalty kick becomes a Western duel. It's two guys facing each other. Destiny and potential death, whether metaphorical or literal. That's why in the penalty kick at the end of the film, I shot it like an homage to the Sergio Leone Westerns I saw when I was a kid, especially The Good, The Bad And The Ugly.
