I have one of the original 'Ghostbusters' guns in my house.

I want my audiences to be as open-minded as my characters.

And the biggest improvement I see between 'Up in the Air' and 'Juno' and 'Thank You for Smoking' is that 'Up in the Air' deals with the complicated human stuff in a way that my other films have not. It's a more articulated film, and because of that, I'm most proud of it.

Look, any guy who tells you that he didn't have some fears is lying. Of course, it's scary becoming a dad for a variety of reasons. That's not to say it isn't thrilling. It was. It was very exciting and in some ways was the greatest thing that's happened in my life. But it's also completely terrifying and you're saying goodbye to a portion of your life and that's just an emotional experience.

'Juno' really changed things for me and I get a lot of screenplays come in now, but I like to self-generate and I like to kind of pursue my own ideas. And I think the more personal the better.

When I think of 'Nightmare on Elm Street,' there was a warmth to those teenagers that I related to. They were not aware that they were in the middle of a horror film, and I really loved those characters and I empathized with them.

And as a director, you make 1,000 decisions a day, mostly binary decisions: yes or no, this one or that one, the red one or the blue one, faster or slower. And it's the culmination of those decisions that define the tone of the film and whether or not it moves people.
