I've been a witness to unfairness in society all my life. To the conditions under which my mother worked all her life, working in an industrial weaving shed in the north of England. And it has been this feature of unfairness that has motivated me in all of my political thinking.

So far as education is concerned, it has had a significant impact on a lot of young people who turn to science as a much more exciting and interesting study than they otherwise might have found, entirely as a result of becoming involved with Star Trek.

The studio have always claimed that the ship is the star of the show, especially when they're renegotiating contracts.

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.

I came to feel very, very sentimental about those sets, which is ludicrous, because they represent everything which is transitory and insubstantial. It's absurd that one should feel sentimental about timber and canvas.

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 made a promise to myself that I would try to introduce something unexpected in every single episode of the series. It was largely to amuse myself as much as anything. I didn't ever want the audience to feel that they knew everything.
