When I was growing up, I never saw couples fight on the family sitcoms I loved to watch. Subsequently, when tough times arose in my own relationship, I wasn't prepared and felt so isolated and alone. Marital issues weren't a part of the narrative that television told me was a 'working relationship.'

My wife is a doctor, and we had a decent life financially. My kids were going to nice schools and had nannies. We weren't rich, but we were better off than I was growing up. And I looked around, and I was like, 'Who are these people?' It was the opposite of what I remembered growing up.

For me, one of the big things I really worried about a lot was nuclear war growing up.

When you're in the middle of it, when you're a kid growing up, you don't think, 'This is my first heartbreak.' You just think, 'My heart is broken.' But then as a parent, you look back, and you see your child go through his or her first heartbreak, and you're realizing, 'Oh my God, this is her first heartbreak.'

This erosion of the middle class is happening all over the place. The opening of a wider gap between rich and poor is always accompanied by such a process.

The studios don't seem to foster good writing. They're not so interested in that, but they're more interested in what worked most recently. They're definitely very serious about making money, and that's not a wrong thing, but you don't have to make money the same way all the time.

I first had the idea of writing a popular book about the universe in 1982. My intention was partly to earn money to pay my daughter's school fees.

At fourteen or fifteen, I decided to earn my living when I grew up playing drums made from wooden beer kegs and leading a group called Keg Brando and His Kegliners. We organized a little band, but it didn't last long and didn't make any money.
