With fiction, you are creating an imaginary world. And it can be a very mechanical process. In a fictional film, you create the characters who become "real people" when facing the camera. When you stop shooting, they change their costumes and become someone else. And people tend to believe in documentary more than fiction. Even if the fiction is based on a true story, everybody will say, "Oh, they're only actors."

It's difficult to make movies. For me it was easier, as a refugee in Switzerland, to make documentary films, because I didn't need a lot of money for it. The way I tell my story or my opinion would be very similar in both fiction and documentary forms. But I found I could speak more effectively to convey this brutal reality through documentary than I could through fiction.

If my friends are going to the mountains with guns to fight, I will continue that fight, not with guns but with a camera.

Even if you make a movie about a criminal locked up in prison, you may not support him as a criminal, but you have to like him on some level. You have to love your protagonist and respect him. He will only open his heart to you when he believes that you are treating him with respect, with love. Only then will there be no more walls between the filmmaker and the protagonist.

When I see that people are touched, and they feel solidarity with him, I say to myself, "I made a little change."

In all my documentaries, I have great respect for the people I work with. Really, I love them. And it's very important for me that when I finish a movie, they stay my friends. It's important that they won't feel that I in any way manipulated them or showed them in a bad light. I want to show them in all their reality - not as subjects but as people with flesh and blood - but I want to do this with all my respect.
