Every man its prisoner... every woman its slave! (taglines)

Dr. Paul Nelson

  • [about his misguided friend, Dr. Tom Anderson] He learned almost too late that man is a feeling creature... and because of it, the greatest in the universe. He learned too late for himself that men have to find their own way, to make their own mistakes. There can't be any gift of perfection from outside ourselves. And when men seek such perfection... they find only death... fire... loss... disillusionment... the end of everything that's gone forward. Men have always sought an end to the toil and misery, but it can't be given, it has to be achieved. There is hope, but it has to come from inside, from Man himself.

Dr. Tom Anderson

  • I made it possible for you to come here... I made you welcome to this Earth... You made it a charnel house.

Claire Anderson

  • [raising her rifle] You think you're gonna make a slave of the world... I'll see you in Hell first!


Dr. Tom Anderson: Do you have any idea what you're listening to?
Dr. Paul Nelson: London Philharmonic?
Dr. Tom Anderson: It's Venus.
Dr. Paul Nelson: Uh huh.
Dr. Tom Anderson: Venus.
Dr. Paul Nelson: Why not? We've bounced signals off the moon's surface. There's no reason that Venus shouldn't radiate impulses.
Dr. Tom Anderson: No, I don't mean the static. Can't you hear it? The other thing?
Dr. Paul Nelson: ...What other thing?
Dr. Tom Anderson: Listen to it Paul! Listen to the voice!

Dr. Tom Anderson: I'll still need you even when there are no emotions.
Claire Anderson: [bitter] For a few dollars you can hire a woman who'll fulfill all your fetishes. And when you get tired of her you can run down to the employment agency and hire another.

Dr. Tom Anderson: He wants you on his side. Next to me, he wants you.
Dr. Paul Nelson: And you want me to condone this reign of terror? To swear allegiance to this monstrous king of yours? To kill my own soul and all within reach? Well, I won't, Anderson. I'll fight it 'til the last breath in my body. And I'll fight you, too, because you're part of it – the worst part. Because you belong to a living race, not a dying one. This is your land, your world. Your hands are human but your mind is enemy. You're a traitor, Anderson. The greatest traitor of all time. And you know why? Because you're not betraying part of mankind – you're betraying all of it.
