Kinsey's quest was really for us all to be tolerant and accepting of each other.

I thought, well of course, Kinsey absolutely adored teaching. He was a wonderful teacher. So these kids really inspired me. So that was a clue I hung onto. He loved young people, he absolutely loved them. And he loved teaching them and trying to help them.

And the Institute sent me a little film footage of Kinsey himself preparing to do an interview for television to talk about his work, so that was quite valuable for me.

Well, from an acting point of view, I bear no relation, I don't look like Alfred Kinsey at all, but I thought somewhere in my artist's soul, my actor's soul, I could capture something of the spirit of the man.

I think there must be some other life forms, even if they're microscopic.

I certainly notice the vitality in Belfast, which wasn't there in the Seventies. There was a war going on then. Now there are cranes everywhere. There really is a sense of renewal and hope.
