Leonard Nimoy credited as playing...
Dr. David Kibner
- Dr. David Kibner: We came here from a dying world. We drift through the universe, from planet to planet, pushed on by the solar winds. We adapt and we survive. The function of life is survival.
- Dr. David Kibner: Face it, Bellicec, you got some friends who enjoy playing practical jokes.
- Jack Bellicec: I don't have any friends, Dr. Kibner.
- Dr. David Kibner: Then, some enemies.
- Matthew Bennell: [Elizabeth and Matthew are captured by snatchers in the Health Department office. Kibner gives them sedatives, so that they can be snatched while asleep] Listen, we're not the last humans left. There are people who will fight you. They will find out what you're doing here.
- Elizabeth Driscoll: They'll stop you.
- Dr. David Kibner: In an hour... you won't want them to. In an hour, you'll be one of us.
- Dr. David Kibner: Elizabeth, could you please tell me, in your opinion, what is going on?
- Elizabeth Driscoll: People are being duplicated. And once it happens to you, you're part of this... thing. It almost happened to me!
- Dr. David Kibner: It's like there's some kind of a hallucinatory flu going around. People seem to get over it in a day or two. All I can do is treat the symptoms.
