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 was running the risk in Adventureland, even though we stayed close to the script, because I wanted it to be not a schematic movie. For better or worse, it's not a wish-fulfillment movie. It's got a kind of happy ending, but it's not like I forgot to put on the "Ten years later," and they've got four kids and a dog. Those guys are not together today. It always was leading up to the moment of "Oh, I have my first girlfriend." Credits.

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 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 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.

My first love will always be movies.

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.
