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.

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.

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.

I'm a huge fan of Zach's [Galifianakis] and I auditioned Zach a million years ago on a movie called Duplex which I was fired from. But Zach came in - It was like 2000, maybe - as a buddy stand-up that people were starting to notice and there was something about him I loved. He wasn't quite right for the part in [Keeping Up with the Joneses] and I got fired anyway, so who cares? But I always wanted to work with Zach.

Brian Eno records and music became a huge obsession of mine in college, in a way that a pop song can provide solace. I don't know if it's shallow or silly, but it meant so much to me.

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.

I don't see that many movies where people are depicting middle-class suburban life in a more textured way. My feelings about the suburbs are not so wonderful, so my movies tend to be a little melancholy.
