The Day the Earth Stood Still1951

Bobby:
[indicating grave marker during a visit to Arlington] That's my father. He was killed at Anzio.

Klaatu:
Did all those people die in wars?

Bobby:
Most of 'em. Didn't you ever hear of the Arlington Cemetery?

Klaatu:
No, I'm afraid not.

Bobby:
You don't seem to know much about anything, do you, Mr. Carpenter?

Klaatu:
Well, I'll tell you, Bobby, I've been away a long time. Very far away.

Bobby:
Is it different where you've been? Don't they have places like this?

Klaatu:
Well, they have cemeteries, but not like this one. You see, they don't have any wars.

Bobby:
Gee, that's a good idea.
