Any time I think out loud, 'I can't believe this is my job,' and remember I am a very lucky duck. Whether marshalling hundreds of zombies, doing crazy stunts or shooting big music numbers, I just feel fortunate to have made my passion my vocation.

The muscle memory of filtering away all the wrong versions of what you're doing improves the more time you're on a film set. I feel like my problem-solving algorithm got kicked up a notch.

Everybody, including me, has to submit to what it needs to be. The thing is at the top of the pyramid, the best version of the thing; we all have to serve that. You forget that at your own risk. And I think movies are too long, in general.

I recently decided that I'm not an originator. I'm a synthesist.

I look at other filmmakers and see skills in them that I wish I had but I know that I don't. I feel like I have to work really hard to keep myself afloat, doing what I do. But I find it pleasurable.

Traffic is about drugs. As detailed a portrait as I can muster about what is happening in the drug world, from top to bottom, from policy to how things move on the street.

Stuff I like is getting trashed and stuff that is being praised I think is terrible. I don't really feel in sync with what's happening, but at the same time, what I think keeps me afloat is that I try not to be, and don't want to be, very indulgent. I try to make the films as lean as possible, and to not spend a lot of time crawling up my own ass creatively.
