Long, long before I became a filmmaker I was talking to killers. Filmmaking was an after thought.

You can talk about a caption underneath a photograph being true or false, because there is a linguistic element. You can claim that a photograph is a picture of a horse or a cow, but it is the sentence that expresses the claim, which is true or false, not the photograph.

Basically, "Making a Murderer" chronicles a set of crimes committed in Wisconsin: Manitowoc, Wisconsin. The first crime is a miscarriage of justice. Steven Avery is convicted and sentenced to a very, very long prison sentence for the assault on a woman. And it comes to light through DNA evidence that he was not the assailant.

Maybe [killers] is one of my real passions. Why deny it?

When you start talking about the known knowns and the unknown unknowns, you're thrown into a crazy meta-level discussion. Do I know what I know, do I know what I don't know, do I know what I don't know I don't know. It becomes a strange, Lewis Carroll - like nursery rhyme.

I don't think that anybody really makes films quite like mine. That's maybe true of any filmmaker.
