One of the pitfalls of writing about illness is that it is very easy to imagine people with cancer as either these wise, beyond-their-years creatures or else these sad-eyed, tragic people. And the truth is people living with cancer are very much like people who are not living with cancer.

There is a lot of talk in publishing these days that we need to become more like the Internet: We need to make books for short attention spans with bells and whistles - books, in short, that are as much like 'Angry Birds' as possible. But I think that's a terrible idea.

I haven't modelled since I was 12 - that was a one-time thing, and I did it as a kid to make a little money to save up for university. Acting is my first love as well as writing and eventually producing and directing.

From 1961 to 1964, I was fortunate enough to work at a think tank in the Kenwood neighborhood of Chicago. As a writer and editor, I reported in a publication about the thinkers. Our offices were in a former mansion; I worked in what had been the ballroom. As I sat typing my copy, I imagined the dancers waltzing.

When I get the possibility of using a character like Bruce Wayne or Dick Grayson, I try and think about what's most exciting or interesting about them as a person, so I try and think what they are at their core, or what piece of their psychology do I gravitate toward that I respect, and I'm excited by it when I read books about them.
