I am very interested in the small decisions people make that do set you on a different road in your life. As much as we have influence over what kind of person we're going to become, there are little tests along the way.

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 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.

I think Stanley Tucci was having an affair with his mother. He had this odd quality that I haven't seen him ever get to do again in a movie that just made me think he's got some chops. He's got a strangeness to him, but he's also clearly been stuck in this role because of his looks and his type. He's been really pigeonholed, I felt.

It actually took me 20 years to want to write about my youth. I was definitely always a little intimidated about writing about that part of my life.

Brian Eno records and music got me through. It made me feel like there were other people out there who had the same questions and fears and unhappiness. Particularly those kinds of artists who were writing songs about exactly those things.

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.
