I always give one actor an emotion to make it very easy so he or she can root to it.

I love Atlanta. It's a great city with great crews there.

I think every filmmaker in Europe would be lying if they didn't say one day they just wanted to make a movie here in Hollywood or at least try it. It's very different from European filmmaking, because here it's like a real industry. It's very much about money and making money, which I think is fine, because it's very expensive to make movies.

Each shooting day is a big challenge, but it's also fun.

Cinema is the most challenging art form that you as an artist can create. It's easier to paint a painting because you're very alone. You just have the canvas in front of you and then you do stuff. I'm not saying it's easy to paint, but it's a solitary thing. Whereas movies combine so many different things from pre-production to production, sound design, production designing, leading, organizing, while still being creative.

It doesn't matter if you work with an Oscar winner or if you work with an unknown actor. There is always a collaboration between the director and the actors, and you always have to listen as the actors have to listen to you as a director.

I was born in Switzerland. Everyone thinks I'm Swiss, but I'm actually German. I'm from Germany.
