Measurements, observations, descriptions can only be considered scientific when they are independently confirmed by other people.

I come from a documentary background and my natural tendency, as a filmmaker, is to make a movie, if I have something to talk about. If it's not about anything that matters, I don't feel like doing it. I'm not against people who make movies just for fun, but I'm not one of those guys. I just want to provoke thinking and debating about certain issues.

Pretty soon we'll have robots in our society, you're going to have a lot of automated processes that used to be done by people - this is happening. Society and technology is changing so fast, and the impact of the change on society and technology is global, not local.

It's all about this abstract entity called the story. It's all about the best way to tell the story, and to make a movie about the issues that this story is about. Filmmaking is storytelling, for me.

You never find yourself involved in a single action story. Your family is always being with you. And you cannot separate whatever is going on in your life with your relationship with your son, with your wife.

Either you look back and deal with your hypocrisy, or you dismiss it.

How can I make a movie about the violence of the police if the police aren't going to let me film it?
