I was always interested in acting and writing, and I honestly thought I'd make my name as a scriptwriter one day. But somehow, I ended up in London in the early '70s, and that's where I had my David Bowie adventure.

Looking back, I can see that my life with David was molded by forces beyond my control and even my understanding. Still, I don't regret trying.

I've always been a Marvel fan. As a kid, I would pick up a two-foot stack of comics and read them in the back of my dad's car on long journeys across the States. That's how I used to make friends - I'd meet up with other kids, and we'd swap comics.

Being a grandparent doesn't interest me whatsoever. Babies are all right if they're your own, but I'm not interested in other people's. It's something you tolerate because they are yours.

I love stories with love in them. I just prefer those films. Every so often, I come across a film where there's no love story. It doesn't have to be romantic, but there's a lack of love, and I don't get that.

I think that whether you're married or not, in any relationship, there's always the terror that you're going to screw something up.

I guess there were things about the Obamas I discovered that I do think are universal to marriage. I found it very interesting in my reporting that their most difficult periods in the White House almost never seemed to coincide. When one was down, the other one was holding it together. In my experience, that's true of marriage generally.

If I can be my crazy, wild self in front of a person, and he still likes me, that's romantic.
