I don't really talk about this because it seems indulgent, but I lost my hair, I'm bald, I had alopecia in my teens. That was back in the late '80s, well before people shaved their heads. So it's probably one of the reasons why I have been obsessed with that age, because it's locked in time where I feel like I had this personal loss that so affected my vanity, and I don't really feel like I handled it well. I'm so much older now, so it's not a big deal, but when I think back at it, I can conjure up how I felt then.

One of the dangers of making a movie about young people is it's potentially trite.

Jon Hamm was the first I thought of for the other role in [Keeping Up with the Joneses], I recently worked with him on Clear History, an HBO improv movie that we had done together.

I was in college - Carnegie Mellon, which is one of the reasons Pittsburgh was appealing to me - and I personally feel that whole world of what we used to call "college radio" is a big part of what kept me sane through a period where I stopped dating, I felt like a freak, I felt like no girl would like me. You know, a very adolescent response to losing my hair. I turned to obsessing about The Replacements and The Smiths and R.E.M. and getting further into The Velvet Underground. People who, in my sheltered suburban life, I knew of, but didn't know fully.

Isla [Fisher] is so pretty we were trying to decide who the hell should play against her that would intimidate her, and one day I said, "You know...this was before Superman had come out, Superman v. Batman: The Court Room Drama I like to call it.

I lived on Thompson Street in SoHo for 13 years and I watched it go from a little Italian neighborhood to the Mall Of America. Then the obvious fact that it's pre-Internet, pre-cell phone. Everyone I think thinks their youth is a more innocent time. I just don't know.

Believe me, there is a ton of stuff we shot on Superbad that was unusable, because people were just riffing and riffing. It's just part of the Judd Apatow method, and part of the technique is to also be able to rewrite the movie again in the editing room.
