- Michael Crichton: There's a big difference between writing and this kind of thing. Writing's really a solitary occupation. And there's also something anti-social about writing. Directing, on the other hand, is really the opposite. I mean, it's not merely enough to get the best out of yourself. You also have to get the best out of the people you're collaborating with.
- Michael Crichton: I tried the idea of Westworld as a novel, and it didn't work. It's in some way, you know, really a movie. Most of the fantasies about the Wild West, or about medieval Europe, or about Imperial Rome, are *movie* fantasies. I mean, they're not what people got from reading history books; they're what they got from looking at Douglas Fairbanks and John Wayne, and that stuff. So, so in some strange way, it doesn't work on paper at all. It only works - as images.
- Michael Crichton: I don't think the premise is far-fetched at all. In fact, whether or not anybody will actually build a resort like Westworld, exactly like with robots, is more a question - it's not a question of technology, because the technology is essentially there. I mean, if you go see Abraham Lincoln at Disneyland, you know, it's pretty good. And they can do better than that now.
- Yul Brynner: I've really got the classical Western, huh? Played by - a highly developed machine. Therefore, the reactions may not be necessarily human. Now, three times he gets severely, severely damaged by the character that Dick Benjamin plays.
- Richard Benjamin: This movie is a total adventure story - told clearly, in terms of conflict. And it moves. You get to go places.
- Narrator: The trademark of a Michael Crichton story is that the more complex a society becomes, the greater the danger of something going wrong.
- Yul Brynner: Something goes wrong. The programming is so sophisticated that he finally cannot stand it - to be constantly shot - and he starts killing. He starts repeating what his enemy did. Then, he starts smiling. The closer he gets to killing, the more he starts feeling warm and become more of a human being.
