By the time you are 30 you are still trying to make your 15-year-old self happy but you are a different person. You need to be brave and let go of that.

As a general thing, I've always been drawn to characters who appear to be one thing on the surface, but are actually something else underneath.

In terms of how prudish Americans were in the '40s and '50s, I have absolutely no idea. I do know about the character that I play. And I don't think it's about being prudish. I think it's about trying to balance a sense of control in this man's life.

Getting older is a struggle. I always feel that just under the surface of acceptance and enjoyment of the ageing process is a terrible hysteria just waiting to burst out.

'Hamlet' is one of the most dangerous things ever set down on paper. All the big, unknowable questions like what it is to be a human being; the difference between sanity and insanity; the meaning of life and death; what's real and not real. All these subjects can literally drive you mad.

I think parenthood is a wonderful balancing act. On the one hand, you want to spend as much time with your children as possible. On the other hand, you want to set an example for them to see that you're fulfilled in your life and in your work.

My experience of working on this show, even though there is so much about sex and sexuality, and we find out a lot of facts and statistics that are very interesting, in their own right, I found that I started talking about relationships more, and the emotions, the difficulties and the challenges. So, I became far more open about that, which I think is probably an indication with the show itself.
