Robert Redford in The Candidate. It's the last line spoken in the movie and the first line written for the script.

Unfortunately, it's a nonspecific line and is also spoken in Cool Hand Luke, 12 Angry Men, The Thing, Basic Instinct, Dogma, Sister Act, Evil under the Sun, Chitty Chitty Bang Bang, Godzilla, Wag the Dog, The World Is Not Enough and many, many more (I got tired of looking them up). Kay may have been thinking of one of those. Too generic to tell.

New one. "I don't want my daughters growing up entitled and spoiled. And I agree with my father -- you give your children enough money to do something but not enough to do nothing."
