Famous quotes containing the words double and/or action:

    “Hollywood held this double lure for me, tremendous sums of money for work that required no more effort than a game of pinochle.”
    —Ben Hecht (1893–1964)

    “In the life of the human spirit, words are action, much more so than many of us may realize who live in countries where freedom of expression is taken for granted. The leaders of totalitarian nations understand this very well. The proof is that words are precisely the action for which dissidents in those countries are being persecuted.”
    —Jimmy Carter (James Earl Carter, Jr.)
