I've never found kicks to the groin particularly funny, although recent work in the genre of the buddy movie suggests audience research must prove me wrong.

When I write a political column for the Chicago Sun-Times, when liberals disagree with me, they send in long, logical e-mails explaining all my errors. I hardly ever get well-reasoned articles from the right. People just tell me to shut up. That's the message: "Shut up. Don't write anymore about this. Who do you think you are?"

A movie is not about what it is about. It is about how it is about it.

We all are born with a certain package. We are who we are: where we were born, who we were born as, how we were raised. We're kind of stuck inside that person, and the purpose of civilization and growth is to be able to reach out and empathize a little bit with other people. And for me, the movies are like a machine that generates empathy. It lets you understand a little bit more about different hopes, aspirations, dreams and fears. It helps us to identify with the people who are sharing this journey with us.

What we have here is a rousing boy's adventure story, adapted from stories that Edgar Rice Burroughs cranked out for early pulp magazines. They lacked the visceral appeal of his Tarzan stories, which inspired an estimated 89 movies; amazingly, this is the first John Carter movie, but it is intended to foster a franchise and will probably succeed.

Why are some people bullied? Because they are different. How? It doesn't matter.

James Cameron's films have always been distinguished by ground-breaking technical excellence.
