We've made too many compromises already; too many retreats. They invade our space and we fall back. They assimilate entire worlds and we fall back. Not again! The line must be drawn here! This far, no further! And I will make them pay for what they've done!

When I'm meant to be standing in the wings, the only way to go is the ladies' toilets. It's the only time I've ever acted in the toilets.

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.

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.

I am told that there have been over the years a number of experiments taking place in places like Massachusetts Institute of Technology that have been entirely based on concepts raised by Star Trek.

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.

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.
