Maurice Evans as Dr. Zaius: "All my life I've awaited your coming and dreaded it, like death itself."

Charlton Heston as George Taylor: "Why? I've terrified you from the first, Doctor. I still do. You're afraid of me and you hate me. Why?"

Evans: "Because you're a man... And you're right – I have always known about man. From the evidence, I believe his wisdom must walk hand-in-hand with his idiocy. His emotions must rule his brain. He must be a warlike creature who gives battle to everything around him... even himself."

Charlton Heston: "I can't help thinking somewhere in the universe there has to be something better than man."

Charlton Heston: "We're now on full automatic, in the hands of the computers."

Charlton Heston: "You maniacs!... You blew it up!... Ah, damn you!... God damn you all to hell!!"

Charlton Heston: "Take your stinking paws off me, you damned, dirty ape!"

Charlton Heston: "Do you have any weapons? Any guns?"

Roddy McDowell as Cornelius: "The best. But, we won't need them."

Heston: "I'm glad to hear it. I want one anyway."

Charlton Heston: "This whole thing is insane!"

Charlton Heston: "Doctor, I'd like to kiss you goodbye."

Charlton Heston: "It's a madhouse!... a madhouse!!"

Maurice Evans: "You are a menace... a walking pestilence!"
