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."

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.

Jon Hamm was the first I thought of for the other role in [Keeping Up with the Joneses], I recently worked with him on Clear History, an HBO improv movie that we had done together.

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.

Isla [Fisher] is so pretty we were trying to decide who the hell should play against her that would intimidate her, and one day I said, "You know...this was before Superman had come out, Superman v. Batman: The Court Room Drama I like to call it.

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.

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.
