I do what I do in my mother's name because I couldn't help her then. Now I can.

It's been hard on me because flying the Enterprise for seven years in Star Trek and sitting in Cerebro in X-men has led people to believe that I know what I'm talking about. But I'm still trying to work out how to operate the air conditioning unit on my car.

I've often reflected on this in the past weeks as I've been following the presidential campaign: Very often, I thought it would have been great for both of these guys to sit down and be force-fed a couple of dozen episodes of Star Trek.

Comedy today is not what it was years ago. It's always changing, in particular to female comics. No longer are certain subjects considered to be a male preserve. Women can talk about sexuality and their bodily functions and it can be very, very entertaining. It's changed the impact of comedy acting.

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.

Violence is a choice a man makes and he alone is responsible for it.
