It still frightens me a little bit to think that so much of my life was totally devoted to Star Trek and almost nothing else.

I heard police or ambulancemen, standing in our house, say, 'She must have provoked him,' or, 'Mrs Stewart, it takes two to make a fight.' They had no idea. The truth is my mother did nothing to deserve the violence she endured. She did not provoke my father, and even if she had, violence is an unacceptable way of dealing with conflict. Violence is a choice a man makes and he alone is responsible for it.

Having spent so much of my life with Shakespeare’s world, passions and ideas in my head and in my mouth, he feels like a friend—someone who just went out of the room to get another bottle of wine.

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.

Violence is never ever a choice that a man should make.

Laurence Olivier said if you have ambition to be a serious classical actor, you must be as fit as an athlete. For me, the breakthrough was going to live in California. I exercised. I drank less. It was one of the things about California that had a positive impact on me.

Whenever the lion fish in the fish tank in the captain's ready room died it was always a sad moment.
