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 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 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.

The first person I met in the business was David Heyman, who was a producer on Daytrippers and who went on to produce the highly-unsuccessful Harry Potter series.

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.

Jon Hamm is incredibly good at playing people who have secrets and are hiding aspects of their personality, and obviously Don Draper had a lot of that.

I was naïve when I was young, I was sheltered. I had illusions about who I was going to be, delusions, and a little bit of pretentiousness. And I thought, "I'll write the guy like that. It'll allow me to make fun of everyone else if I make fun of myself."
