I never got to the point where I felt that nonviolence was not viable. ... I realized that it wasn’t that it wouldn’t work, it’s that people didn’t follow the proper steps in trying to achieve it because there are a set of principles and there are a set of steps in the methodology that we were taught about nonviolence. And when we follow those they work.

I think it's … the profession is starting to realise that in part it's the general climate, and the way we treat each other is not conducive for having more women in the profession. It's not just about promotion but it's about the general environment and how people talk to each other and address each other in seminars and things like that, that we need to work on a culture that is more respectful and that will be more acceptable for many women who think that they don't want to play the games of shouting at each other.

I’d read some of the things that Don Glaser wrote, for example, and they’re imaginative physics, they’re not quite such good biology. There was a consensus that said you had to be able to reach out from physics and get to some of these things you’d like to, but then you have to know enough about the biology that the whole thing makes sense. And you really have to present things in such a way that a community develops. I didn’t realize that at the time, but certainly one of the important things of what I did had to do with enabling people who came from physics, or who came from biology, become a community, working on not just one little problem or piece, but somehow collectively working together toward trying to get an understanding.

Some writers claim to extrude a book at an even rate like toothpaste from a tube, or to build a story like a wall, so many feet per day. They sit at their desk and knock off their word quota, then frisk into their leisured evening, preening themselves. This is so alien to me that it might be another trade entirely.

I liked all the normal kinds of adventure books, Kidnapped, Treasure Island, Huck Finn sorts of things. I loved Swiss Family Robinson and that whole period of South Sea adventure movies. I liked westerns. Westerns were very big when I was growing up. When we finally got a television there was a whole run of westerns on television. John Wayne films, directed by John Ford, before I knew who John Ford was. I think those were very influential in my enjoyment of movies.

Whenever you’re making a movie, especially when you’re writing, you always have self-doubts. I did the first location shooting in Tunisia.
