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'm really glad to have made a movie that way on Superbad, because I learned a lot about what can be done and what the limitations are.

I feel like I came from a generation where... We didn't have Vietnam. We didn't have World War II. Nothing cultural was thrust upon us to make men out of us, so you're kind of free to not grow up that way if you don't want to.

I feel this way about a lot of movies, that the characters are idealized versions of people. For better or worse, I am as fascinated with human flaws as anything.

When I was a TV director working on Judd Apatow's show Undeclared. I was surrounded by so many young people. People like Seth Rogen, who was 9 years old or something. It was just a ridiculous amount of talented young people. I started to think I'd like to see a young-love movie, but not one done in that glossy, Hollywood, high-concept manner we've become accustomed to. One that was, for lack of a better way of putting it, a little more ambiguous, '70s-style, where everyone was flawed, middle-class characters.

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.
