One of the things that I've come to understand is that as I talk a lot about Picard, what I find is that I'm talking about myself.

During the course of the seven years I played scenes with an oil slick, I played a scene with a grain of rice. Sometimes with indescribable creatures. I remember having a conversation with something which was simply a smell, that's all. It was part of our job.

I know it feels like two steps forward and one step back, but we are making progress. In my lifetime, I have lived through one World War, I have lived through the end of Apartheid in South Africa, the pulling down of the Berlin Wall. I have experienced what I never thought I would have experienced, which is a pretty workable peace in Northern Ireland, and I experienced a unified Europe - until the Conservative government got its hands on the idea that in order to appease a few back-benchers they would hold a referendum, what a disastrous idea.

The people who could do most to improve the situation of so many women and children are in fact, men.

And from the first moment that I ever walked on stage in front of a darkened auditorium with a couple of hundred people sitting there, I was never afraid, I was never fearful, I didn't suffer from stage fright, because I felt so safe on that stage. I wasn't Patrick Stewart, I wasn't in the environment that frightened me, I was pretending to be someone else, and I liked the other people I pretended to be. So I felt nothing but security for being on stage. And I think that's what drew me to this strange job of playing make-believe.

I've been in politics all my life. In 1945, I committed my first act of civil disobedience during the election campaign for the first post-World War II general election, when the Labour Party, to everyone's amazement, ousted the Conservatives. I refused to obey the instructions of a policeman, and as a result, almost got a belt around the ear, because those were the days when policemen could hit children and nobody cared, they thought it was probably good for them.

An obsession might be a little strong a term, but it has now become one of the most significant aspects of my life, but most importantly of my career, because it has changed the public's perception of who Patrick Stewart is.
