Conservative values aren't really reflected in the radical values of the NRA. And the other idea was that the NRA is not what you think it is: It's an evolving, ever-changing organization, and it has not always been this radical, right-wing arm of the Republican Party, and that the history of the NRA is in fact really interesting.

It's powerfully important for me as a pro-choice person and person who supports Planned Parenthood to have Rob accept me as not a baby-killing horrible person. That's actually a massive step away from his original position, and he's taking a lot of heat in his world just for being my friend, just for hanging around with me.

I've taken it from feminist friends, and I've taken it from lefty friends too. But that reassures me. If the right is attacking us and the left is attacking us, that's exactly where we want to be.

I get very close to people when I'm shooting them. We would go and shoot a scene with Lucy, and I would spend the whole time telling her about Rob. Then I would go shoot a scene with Rob and tell him all about Lucy. Eventually they wanted to know each other. These are two people who would never have overlapped in any other way or context. We brought to the garden at Rob's office and just sat and watched what unfolded. I remember weeping behind the camera, because I was so moved by the way they connected.

There's a real difference between a documentary that was all about facts and history and information. People just don't get as engaged in that kind of documentary - they don't fall in love, they don't cry, they don't forget who they are, they don't ride with you. As we realized we had richer, vérité kind of people, what we wanted to do is focus in on the vérité story.

Once we got to know each other, we had such similar impulses. We saw in a similar way, and we developed a strong friendship. We would talk on the phone for hours, philosophically and theologically, about all of these issues.

There are very few people who have committed more to the pro-life discourse than Rob has. He's spent time in jail. He has really lived it. He has committed everything he's had to it. If in fact he believes that every human life was sacred, I knew that if he had his conscious awakened, I knew he wouldn't be able to close his eyes to it.
