In the case of two actors connecting with each other and trusting each other, our bodies have memories without us having to consciously think about it, so rather than think, "Oh, I must think about my daughter dying," you just let that go and trust that you have all the emotions you need in there, and by losing yourself in the scene, that stuff kicks in without having to spend the day thinking about horrific things happening to your own child.

And so, in terms of setting the right tone and finding a way of presenting all of these things, that creates a cohesive whole and doesn't alienate the audience, is tough. That's a challenge. And I think the tone of a lot of shows is discovered through experimentation and actually making it. Eventually, it starts to cohere.

I can be a lazy dresser.

But obviously, things have changed in many ways since the '50s, when the show is started, in terms of sexuality, and how much access we have to images of it and information about it. But, the same problems always apply. It doesn't matter whether we know a lot more about sex now or if there's a lot more access to it. The same problems of intimacy, of dealing with other people, of connecting and being vulnerable with other people, which is what the show is ultimately about, still applies now, I think.

I am prone to get carried away thinking about creative projects.
