Sometimes in the studio movies I've been working in, you'll put a joke in a movie because the crowd loves it - not because I love it.

I always cast people with a sense of humor because people that are super serious don't understand when I ask them to eat a booger it's not necessarily about that. It's about something more. It's about inviting a little bit of absurdity into the process and humanity into the process. Making sure that no matter who we are and what sort of pedestal or glamorous lighting we're under, we're all eating boogers man.

A lot of my best friends are the best person for the job in a film, but sometimes being a filmmaker I'll give a buddy a chance to prove himself. Other times I want to go with a tried-and-true person. It can absolutely cause problems.

Everybody's got their tools or their instruments, and it's fun to see how people expose themselves to their profession or their profession becomes who they are.

Sometimes an actor doesn't sell an idea 100 percent. It just sounds like something that's coming out of their head. You can hear the gears whirring and they're trying to think of what the smart approach is to getting a line across.

We were in production on a movie called All the Real Girls, which filmed in the Fall of 2001, and we really discovered who Danny McBride was, as an actor. When I say we, I mean me and a crew and a small audience that would hit the art house. He'd never acted before, and it was a really refreshing, eye-opening experience to watch him unleash, in front of the camera, all this comedic potential that we knew he had, as a human being and as the guy doing keg-stands at the party.
