I think at the beginning of a project, you decide if you're in love with the idea and what it's about, or what you think it's about at that time at least. Then you commit to it, and once you've commit to it no matter what, no matter how many self doubts you have, you're in it. The ship's sailed, you can't turn around.

Finding a kid that could be introspective and internal and thoughtful, and then also be wild and free and guileless and physical, it was hard. So at the end we started getting down to panic time, and we still hadn't found our Max. And we decided to go about it a different way. We said, "Let's just find friends of ours that live in interesting cities in the country that maybe aren't as big, and people that don't do casting." And thinking maybe you find a place that has an artistic community, maybe we'll find some interesting kids from there.

As a parent, your perspective of childhood is through the eyes of this person that you care so much about and you just want the world to be great for them. You want their life to be easy and happy.

I think because I'm not a parent, my most immediate connection to childhood is my memory of my own childhood.

Big emotions that are unexplained are really scary. At least to me.

When I first moved up to San Francisco to write Where The Wild Things Are, I had a couple moments where I talked to somebody, and they're like, "Oh, I love that book. I love this part of it," or, "This is what it means to me." And it's like, "Well, I don't know. I guess that's not what I'm making the movie about." But very early on, I don't know, we sort of let go of that fear.

On everything I do I'm always taking someone's money, whether it's a movie studio or a record label. Somebody's paying for it, and I'm always respectful of that. But I'm never going to compromise.
