I just spent a lot of time on 'ER' for that eight years. I also started working when I was 16, so by the time I left 'ER,' I was 40 years old, I had this incredible experience, my wife had this great company, we had four kids, it was like, 'Let's go to New York and live for a while and make that the priority.'

You know, you never say never because before I did 'ER,' I always said 'I'll never do a TV series,' so that's what I said.

Flying back from New York, the flight attendant said 'God, I wished you were here yesterday, we had a stroke on the plane.' I said, 'If I have a stroke on a plane, I hope the pretend doctor isn't the one on the plane. I want a real doctor.'

It's difficult to keep that perspective, I think, as a parent: to know your boundaries as to what's good parenting or just projecting your own expectations on your kids. That's the hardest.

Knock wood, but I started acting professionally when I was 16, and I've always been able to support myself since then.

To think one film makes a career is ridiculous. It's important to keep perspective and do things other than for money.

David Fincher is a longtime friend. As a director, my wife had worked with him as a makeup artist when he would do Madonna videos years before, and his child and my oldest child were in preschool together, so we're kind of dad-friends through that, too.
