I think I'm a prudent filmmaker.

I couldn't roam wildly and speak secretly with villagers [in North Korea]. No way you could do that. And honestly, I didn't even try. I was realistic of what I could do and yet persuaded them into accepting numerous things that I shouldn't have filmed.

Of course there's a value in a storyboard if you do a big - let's say an action movie and actors have to move and act in front of a green screen because entire backgrounds exploding and cars flying through there have to be created separately, and in this case you better make sure the actors are precisely placed and the background action is moving in a certain moment, for this type of film you would need a storyboard.

There are certainly laws and elements that make a film more accessible to mainstream audiences. If you've got Tom Cruise as a strongman, I'm sure it would have larger audiences, but it wouldn't have the same substance.

North Korea has a very striking mythology there. It is influencing the whole nation.

I see planets that don't exist and landscapes that have only been dreamed.

I have nothing against 3D films but I do not need to see them.
