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.

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.

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.

Most people look at a feature film and say, "It's just a movie." For me there is no border or wall between fiction and documentary filmmaking. In documentaries, you have to deal with real people and their real feelings - you are working with real laughter, happiness, sadness. To try to reflect the reality is not the same as reality itself. That's why I think that making a good documentary is much harder than making a good feature film.

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."

The problem of ISIS is not recent. Ever since the Second World War, people in this region have been, and are today, living under brutal dictatorships governed by nationalistic fervor. As for the Kurdish question: nobody from the Arab world is serious about fighting ISIS. It's only the Kurdish people who are standing firm against ISIS. And I think Europe, the United States, and most other democratic countries of the world are beginning to look at the Kurds in another way. The Kurds are really becoming their partners in the region.
