Beneath the Planet of the Apes (1970)

Cornelius: If you are caught by the gorillas, you must remember one thing.
John Brent: What's that?
Cornelius: Never to speak.
John Brent: What the hell would I have to say to a gorilla?

Dr. Zaius: You ask me to help you? Man is evil! Capable of nothing but destruction.

Fat man: You don't understand, Mr. Brent. The Bomb is a holy weapon for peace.

Ursus: He bleeds! The Lawgiver bleeds.

Dr. Zaius: Someone, or something, has outwitted the intelligence of the gorillas.
Dr. Zira: That shouldn't be difficult.

Negro: Mr. Taylor, Mr. Brent, we are a peaceful people. We don't kill our enemies. We get our enemies to kill each other.

Mendez: Glory be to the Bomb, and to the Holy Fallout. As it was in the beginning, is now, and ever shall be. World without end. Amen.

Ursus: The only good human... is a dead human.

Ursus: The only thing that counts in the end is power! Naked merciless force.

Nova: Taylor.

Dr. Zira: Gorillas are cruel because they're stupid! All bone and no brain.
