I'm kind of a failure. I mean, I'll be honest. I'm successful in that I'm getting to work on great stuff, but I think I'm a failure in all the personal stuff that is most important to me.

Whatever makes you laugh is fine, and all we can do as comedy professionals is try to steer you towards something that we think is a little better - but not put you down or just perplex you in the process.

So many of my friends have always been women growing up... I always feel slightly more comfortable around women because with guys in general there's always more of a danger zone... it's very aggressive sometimes the way guys act with each other, putting each other down and calling each other names, so I was always too sensitive for that and used to hang out with the girls. And they were always really funny to me.

At the end of the day, I just want a movie that's great, that people are going to love and laugh at and be affected by, and also have an emotional journey.

The dueling maturity levels in high school is such a source of comedy to me. I was always such a late developer. I was last to walk. I was last to ride a bike. I was last to have sex. That's why it's fun to portray one side of your childhood onscreen.

I think things go wrong when there's not a very specific plan and specific emotional roadmap. You need to know what a scene needs to get across, and what story point that needs to be advanced, whether it's discovering someone for the first time or whether it's seeing a relationship get strained. What I do as a director is really create a safe environment that everyone can feel very comfortable in and experiment within so that they don't hold back anything.

That's what I love about the mockumentary style, is the added thing of people knowing they are on-camera, which changes your behavior. That's why we sometimes do what we call spy shots.
