I like things that are funny - in everyday conversation, in incidents that you see, in watching TV or watching film. Comedy has always had an impact on my life.

Encouraging people to believe in it was the most important thing of all. It's one of the reasons I was always uncomfortable whenever film crews came on the set to shoot things. I didn't want our make-believe to be exposed.

Tom Hanks knows the name of all the episodes.

As time went on, I did campaign to lighten the character a little bit, to introduce some romance into the episodes, outside activities, horse riding and fencing and mountaineering.

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.

There's no such thing as "just a domestic".

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.
