I think I came back from America a funnier and nicer person than I went.

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.

We've heard from many teachers that they used episodes of Star Trek and concepts of Star Trek in their science classrooms in order to engage the students.

Having played many roles of scientific intellect I do have an empathy for that world. 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.

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.
