Watership Down (1978)

Blackberry: Men have always hated us.
Holly: No. They just destroyed the warren because we were in their way.
Fiver: They'll never rest until they've spoiled the earth.

Narration: All the world will be your enemy, Prince With A Thousand Enemies. And whenever they catch you, the will kill you. But first, they must catch you: Digger. Listener. Runner. Prince With A Swift Warning. Be cunning and full of tricks, and your people will never be destroyed.

Hazel: Lord Frith, I know you've looked after us well, and it's wrong to ask even more of you. But my people are in terrible danger, and so I would like to make a bargain with you. My life in return for theirs.
Frith: There is not a day or night that a doe offers her life for her kittens, or some honest captain of Owsla, his life for his chief. But there is no bargain: what is, is what must be.

Hazel: We'll fill in the holes good and deep. They'll have to dig us out, and they can't stay out in the open for long without attracting elil.
Blackavar: You don't know the Efrafans. They'll never give up.

Hazel: Where are you going?
Fiver: Away, to the hills.
Hazel: By yourself, alone? You'll die.
Fiver: You're closer to death than I am.

Blackberry: You're beginning to sound like a chief, Hazel. 'Hazel-rah'.
Bigwig: Hazel-rah? That'll be the day I call him chief, that will.

Fiver: Look. Look. That's the place for us. High, lonely hills, where the wind and the sound carry, and the ground's as dry as straw in a barn. That's where we ought to be. That's where we have to get to.

Hazel: Are you hurt?
Kehaar: Kaah kaah.
Hazel: If he's hurt, maybe we ought to help him.
Bigwig: A bird? What for?
Hazel: We - help - you.
Kehaar: Piss off.

Fiver: There's something very queer about the warren this evening.
Hazel: Is it dangerous?
Fiver: It's not exactly danger, it's... oh, I don't know. Something oppressive... like thunder.
