I guess bittersweet is probably my favorite tone, as a lover of Woody Allen and Federico Fellini and the French New Wave. You know, old Hollywood, sad movies. I guess it's my picture of suburban life, a lot of it being very, very lonely. I wanted to have that infused into the feeling of it.

I feel like I'm long overdue for a "one for me" movie, so I've got two low-budget indy personal things I'm working on.

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.

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 talked about the summer of 1985, when I worked at an amusement park on Long Island, the kind of place where someone would pull a knife on you if they wanted a better prize than you were giving them. You found a lot of used needles beside the cotton-candy cart at the end of the night. It was a pretty white-trash, scary place. It was one in a series of terrible jobs I've had, coming from not much money and having no particularly resourceful skills. And at one point one of my friends, a writer on the show, Jenny Konner, said, "You should write about that."

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

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.
