I saw how you could get away with such a free-spirited, naturalistic sensibility in a mainstream Hollywood movie, and you could apply a lot of the skills of the '70s icons that I really admire to a contemporary, commercial movie.

The difference between this film [Your highness] and Pineapple Express was pretty much in the logistics of the technical ambition of the movie, and the size and scope of the movie. Pineapple Express was a great success, and that was something that we wanted to capitalize on, but we wanted this movie to be bigger, more adventuresome, bring a bigger audience to the movie, and challenge ourselves to do something new.

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.

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.

One of the things I wanted to do after three, prolonged movies is to do something that was really, kind-of knee-jerk decisions, and artistic instincts and strip down the process to more of a guttural level, and make something that wasn't so manicured and polished; wasn't quite so developed and supported, and just run wild with it and see what happens with it.

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.

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.
