Independence Day1996

[David finds Marty on the phone with his mother concerning the aliens]

Marty:
I know, Ma. Just try and stay calm!

David:
Tell her to pack up and leave town.

Marty:
Why?! What happened?!

David:
Just do it!

Marty:
[to the phone] Ma! Ma, listen! Uh, get your stuff together, and head for Aunt Esther's. Don't argue with me! Just go! [hangs up] David, why'd I just send my mother to Atlanta? David?! David, talk to me!

David:
Did you hear me tell you that the signal in the satellite feed is slowly recycling down to extinction?

Marty:
Not really.

David:
It's a countdown.

Marty:
A countdown? Wait, a countdown to what, David?!

David:
Uh, it's like in chess. First you strategically position your pieces. Then, when the timing's right, you strike. [turns Marty's attention to the monitor] See? They're positioning themselves all over the world usin' this one signal to synchronize their efforts. In approximately six hours, the signal's gonna disappear, and the countdown's gonna be over.

Marty:
And then what?

David:
Checkmate.

Marty:
[gasps] Oh, my God! Oh, my God! I gotta call my brother. I better call my housekeeper. I gotta call my lawyer. Aw, forget my lawyer.
