So one of the profound things we found when studying these congregations, the mixed ones, is just how much overlap and interracial ties that develop not only with the people in the congregation, but they start meeting each other's families, and their friends, and they go to each other's neighborhoods if they live in different neighborhoods, and at work they meet people they wouldn't otherwise met, and so it creates a whole new definition of what the group is.

I think people respond to villains because people in general are more villainous than heroic.

Then of course there are bigger things that matter, like who do I see up there in the congregation? Do I see myself up there? Well, I don't.

I think with President Obama there's going to be a discussion, because he himself is multiracial, because we have for the first time a non-white president. There's going to be talk about what does this mean? What is it? Are we in a new era?

We've done a lot of studies to see when they do happen, why, and I mean there's a variety of reasons. But one, it starts with a commitment where they decide this is going to be who we are. Maybe it's out of their faith, a new way of looking at their faith, that we must be integrated across race.

But in the US, when you have two separate cultures, each with its right, each of which has come to exist in this political entity in the last couple hundred years, each feeling like, "I have the right to hold onto my culture," and that's what makes it difficult.

I've played villains on stage - you know, the Iagos and so on - but I think of myself as a funny person. I mostly did comedies before I did TV work.
