CHARACTER#5: Do something!
CHARACTER#4: Why is everybody so excited?
CHARACTER#7: Because they see hope.
RONALD REAGAN IN ANIMATED FORM: God had a plan for America. I see it as a shining city on a hill. If we ever forget that we are one nation under God, then we will be one nation gone under.
[On screen: Go back in time to see how one man transformed a nation...And the world."]
MATTHEWS: You know I don't know whether that's right from a Cambodian re-education camp or it's chairman Mao's little red book. What propaganda!
