I was lucky that I was getting exposed to a lot of different kinds of films, and I was liking them all. So it seemed logical to me that you could - as in the style of the studio directors of the 30s and 40s - jump from one genre to the next, with the same satisfaction.

I've found through experience that I'm only good when I'm writing something that, in essence, only I could write. The times I've written for hire, for other people, I don't think I've done very well.

I like to know where I am. I don't like the kind of cutting where you don't know where you are.

I know why we can't have a frank discussion with our policymakers - if you're in the government or in law enforcement you cannot acknowledge that drugs are anything but inherently evil and morally wrong.

There's a technical reason why I think that frame rate is weird and it has to with your brain's ability to scan beyond a certain rate. The point is I find it looks weird.

I always have a plan, but then I'm always ready to throw the plan out, and everyone's ready to make a radical left turn if necessary.

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.
