Normal television limits what you can do. With science fiction, you can exercise your imagination more. I fell in love with it.
We stress humanity, and this is done at considerable cost. We can't have a lot of dramatics that other shows get away with - promiscuity, greed, jealousy. None of those have a place in 'Star Trek.'
I wanted to send a message to the television industry that excitement is not made of car chases.
When you get into an airplane by yourself and take off, you find yourself in this lovely, three-dimensional world where you can go in any direction. There is no feeling any more exciting than that.
'Star Trek' says that it has not all happened, it has not all been discovered, that tomorrow can be as challenging and adventurous as any time man has ever lived.
I have felt many times trapped by 'Star Trek.' It cost me dearly. It won't anymore, because I've come to grips with what it is and where it fits in my life.
The ship's transporters - which let the crew 'beam' from place to place - really came out of a production need. I realized with this huge spaceship, I would blow the whole budget of the show just in landing the thing on a planet.
When they put out the sales brochure when we eventually went to series, they carefully rounded Spock's ears and made him look human so he wouldn't scare off potential advertisers.
The Russians were responsible for the Chekov character. They put in 'Pravda' that, 'Ah, the ugly Americans are at it again. They do a space show, and they forget to include the people who were in space first.' And I said, 'My God, they're right.'
