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.

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.

Be what you are. Don't change yourself for anything. God made you that way for a reason.

There's really no point in having children if you're not going to be home enough to father them.

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.

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.'

'ER' was so huge that whatever I did coming back to television, I'd have to feel as strongly about.
