The Day the Earth Stood Still1951

Helen Benson:
I need to know what is happening.

Klaatu:
This planet is dying. The human race is killing it.

Helen Benson:
So you have come here to help us.

Klaatu:
No, I didn't.

Helen Benson:
You said you came to save us.

Klaatu:
I said I came to save the Earth.

Helen Benson:
You came to save the Earth from us.

Klaatu:
We can't risk the survival of this planet for the sake of one species.

Helen Benson:
What are you saying?

Klaatu:
If the Earth dies, you die. If you die, the Earth survives. There are only a handful of planets in the cosmos that are capable of supporting complex life.

Helen Benson:
You can't do this.

Klaatu:
This one can't be allowed to perish.

Helen Benson:
We can change. We can still turn things around.

Klaatu:
: We have watched. We have waited and hoped that you would change.

Helen Benson:
Please.

Klaatu:
It has reached the tipping point. We have to act.

Helen Benson:
Please.

Klaatu:
We will undo the damage you have done and give the Earth a chance to begin again.

Helen Benson:
Don't do this. Please, we can change. We can change.

Klaatu:
The decision is made. The process has begun.
